‘Maurits wrote a serie of beautiful fantasy books about microorganisms for children with the aim to emphasize on the importance of microorganisms for life on earth. The board of the Royal Netherlands Society for Microbiology is very enthusiastic about his books, as we more and more focus on outreach to the general public.’


Dutch royal society for microbiology the KNVM


‘The abyss of Azu, the final part of the Diego Dazzler serie, filled with new adventures... will the young heroes be able to control Krudon Kragt and his endless cravings for more Terrafos?

Besides Diego and his friends, other heroes are present in the story: useful bacteria. These microbes help to make and keep Diego’s World livable: Alcanivorax that eats oil and cleans up waste; Nitrosomonas that eats the ammonium in sweat and keeps our skin clean, the miraculous Methylomirabilis Oxyfera that produces oxygen while breaking down the greenhouse gas methane.

Maurits van Huijstee shows u show we can and must keep our World livable, and how dependent we are on microbes cleaning water, capturing nitrogen, producing oxygen and tasty products of fermentation and breaking down greenhouse gasses.

The whole family has read the four books with great, great pleasure. Diego Dazzler & The abyss of Azu is a great ending to a great story. Absolutely recommended.’

Comment from my 11-year-old son: "I enjoyed it very much and very exciting, and it is one of my favorite books. I really want to read the next part! '

Joost Brinkman


Suuppeerr exciting, very beautiful life lessons too, thanks, we have been glued to the book. '

Evert Lichtenbelt and children (7, 9 and 11)


Should part 4 ever appear .... my daughter is waiting for it!

Annet Klein Holkenborg, Zeist


I lost my daughter (9) for days through this book. She secretly read in her room. And now she wants to be my successor.

Marjan Minnesma, founder and director of Urgenda


Our son (group 6) is a big fan of your books! He has held a book review about it.

Inge Crezee


Comment from my 12-year-old daughter: "I held my book review about Diego Heatstroke and the return of the eagle and I got a ten. Everyone in my class thought it was a very exciting book, but I did it most of all. They also wanted me to read because I stopped on a very exciting piece. I really thought it was a super exciting book. It has now become my favorite book. "

Roland Klarenbeek


'My nephew of 9 read it in one go. It is fantastic that you pay attention to sustainability in a way that appeals to children more than our 'people-language'. It is important that children learn what sustainability means at a young age so that we no longer have to learn bad behavior when they are older. '

Gé Moonen, Moonen Packaging, Weert


Comment from my daughter (9): "I really liked the 2nd part of Diego Zonnestek again! I liked that he was a little fatter because then dad and I could read more about Diego and his friends. It was a very fun, exciting and educational adventure again !! I have learned a lot from it. such as: that you should not use too much terravos / oil but that there is also sun and wind energy. And that that is much better for the environment. And I hope that another part will come. "

Joost Ravoo, Haarlem


Part III was again devoured in a few days, my daughter really likes your books, super!

Martin Haas, Wapenveld


Comment from my daughter (11): I thought it was super fun but also exciting and pathetic.

Laura van den Bosch


My son found him (even) more exciting than part I ...

Anneclaar Weijers (2), Kockengen


My daughter (11) even did her book review about this book, she liked it so much!

Josette Voskuilen, Montfoort


We enjoyed Diego2. I read the book and we could not put both books down so exciting. And every time wondering what would happen again. With everything and everyone. Exciting, constructive, good narrative concerns the environment and super cool solutions as an alternative to greener electricity. All in all a big recommendation for both children and parents.

Angelique de Winter Oomen and daughter


According to my daughter, he was completely great!

Maikel van den Corput


Comment from my son (9): 'Part 2 is SUPERCOOL, certainly just as fun as part 1. So cool, that my book review must be about it! And once part 3 is there, I want it!

Janneke Krooneman


Your book was devoured by my oldest of 11 and I enjoy reading it to daughter of 9!

Anne van Elsen


Comment from my son (11): 'I thought it was a very nice book. It is very useful if you have read the 1st part. There is a lot of fantasy in it and I could also empathize with Diego Zonnesteek in this story. Sometimes I really thought "do not do that!". I thought it was great to be a test reader and I would definitely recommend the book to my classmates. I hope that part three will come! "

Dick Boeve, Driebergen


Comment from my son (12): I thought it was fun and exciting, there was more action than in the first, I liked that.

Yvonne Rokitta


My compliments for your book! I have read it with a lot of pleasure in a few days. It becomes a bestseller.

Erik Groen


My son (11) has read the books independently (!). He found it exciting and went through it like a spear.

Marc van Grinsven


Part I found my daughter (9) too crazy, and about part II she did her book review because she liked it so much! You can not get a bigger compliment.

Niels Mulder (2), Amsterdam


I have read part II of Diego Zonnestek, just like part I, in one go. Once I started the adventure, I was eagerly looking forward to what Diego and his friends would all come across. The green transition as an exciting adventure for young and old. Not just imaginative adventure, but something that we can all contribute to in our daily lives. Hopefully these books will make many more people aware of the great opportunities that exist for a more sustainable society. On to Part III!

Silvia Heijnen, Limburg


'Our 9-year-old son will be talking about his magic spectacles next week. Julian van 11 looks in the morning whether the "Eagle" has already landed in the mailbox ... great books. "

Ron van Ommeren


Last week I read part I and II in succession. Great books for large (I 48) and small (my kids 10 and 12) and also to give as a gift (fits my function manager environment with a small municipality). Thanks for the exciting reading hours!

Manon Stok


My eldest son (12) read it: He thought he was even better than part I, and he already thought it was great!

Simon Morsink (2), Bussum


Maurits, thank you for bringing me back to the reading path. I read both parts in one breath during our holiday in Greece. What appealed to me was the descriptive writing style that caused you to smell the dirty air and hear the water thumping through the village. In addition, the parallels with the now and lines that are to be continued in the near future. This style makes both books timeless. I therefore eagerly look forward to the following parts because it tastes like more.

Rob (55 years old), Naarden 

The first book review about Diego has already been given here in Heemstede! My daughter used part 1 as a basis last week and of course referred to part II. Many enthusiastic reactions in the classroom and everyone wants to read it. Part II is, if possible, even more fun than part I. She sticks to the idea that part I says that it is a series and therefore does not end with only two books. Full of expectations of part III!

Caroline Blommers


My 11-year-old son read it again in one go and found it super exciting. A big compliment! That rarely happens to him.

Cora Zaaijer-van Muiswinkel (2), Middelburg


Comment from my son (12): "Even better than part I." He has read it in two days and a night.

John Nouwens (2)



Roger Cox, lawyer of Urgenda in the won trial against the Dutch government, the so-called 'climate case.'


The gorge of Azu, the last part of the thrilling Diego Zonnestek series. Plenty of new adventures. Will it succeed the young heroes to control Krudon Kragt and his terrace fanatic?

Besides Diego and his friends there are also other heroes in the story, namely useful bacteria. These bacteria help to make the world of Rebequin liveable and to keep it:

Alcanivorax from the Bobasken salt which feeds oil and cleans up pollutants; Nitrosomonas that sweats the ammonium in sweat and keeps our skin clean and the miraculous Methylomirabilis Oxyfera bacteria that makes its own oxygen to break down the greenhouse gas methane.

Maurits van Huijstee shows how we can and should keep our world liveable and depend on micro-organisms that clean water, capture nitrogen, produce oxygen, prepare delicious fermentation products and break down greenhouse gases.

The whole family has read it with great pleasure. Very nice end of the whole story. Recommended.

 Mike Jetten, professor of Microbiology and Spinoza winner 2012



Jan Paul Schutten, two-time winner of the Gouden Griffel


Without exaggeration: my sons have fought for it and then devoured him. And that rarely happens to them!

Merle Pikkemaat, Vreeland


"A chapter every night; to read aloud. Also with the return of the Eagle we are taken back into a special world. We live with the adolescent Diego who is hard to know with his special qualities. Excitement, sensation, and humor with a nice responsible message. All of this time! "

Jikke & Matthijs (30-years but sure fan!)


I believe that personal development gives meaning to life. With that development you can not start early enough. Maurits contributes with his trilogy about Diego to a positive development of me and my children. How wonderful it is to see during the reading that the children find it very logical that you can generate energy with kites, bacteria and other innovative inventions. It gives me the hope that our children from this natural logic that they are given by Maurits will do what our generation still has so much trouble with. Diego makes adults think about their own role in society and gives children a good example of how you can contribute to a healthy and safe society. Finally: It is a nice exciting children's book that you as an adult (for) reader also enjoy.

Yuri Pelser


My daughter of 9 thinks the books are great. I also like them as a parent, both the spelling and the environmental and business policy aspects that are introduced in a playful way.

Edwin Roestenburg, Oegstgeest


Both my son and daughter loved the book Diego Zonnesteek. Read with pleasure!

Claire Reeves, Haarlem


My daughter (11) thought it was a nice book, because (as she said) Diego is a special, interesting and funny child. My other daughter (from 9) also, and said that it is also different from other books, as I understood by the variation in emotions in the book!

Marc Smals, Utrecht


My daughter has read part 1 and liked it so much that she did a book review last week. Part 2 has yet to be started. We had already read in the newspaper about part 3 (bacteria I believe) so are very curious!

Sarah Splinter, Utrecht


My daughter thought it was a fun and imaginative book. And looks forward to your new book.

Afke van der Velden, Maarssen


dear Maurits, I think your books are soooooo nice. part 1 I have already uit.some pieces I found quite difficult to understand but eventually I understood it.I read now part 2 I find it very exciting

Merijn, Apeldoorn


I find Diego Zonnestek a very nice book and I hope that part III will come out soon!

Success and pleasure with writing (this is what my mother types).

Greetings from the daughter of Sylvia

Sylvia Peters, Zeist


We are already looking forward to part 3. We, because I read the books about dyslexia of my son. That is not a punishment because I just enjoy it.

Johanna Blankensteijn, Oegstgeest


I have read the books both. I liked them very much. I can not wait for the third part.

Beau (9), Bilthoven


Diego really liked it. My son is 12, he is a mishmash of tough and scared. Cool on his waveboard, on a zip cable car, with his friends, on instagram. Afraid of the dark, afraid not to be popular enough, afraid of Ebola and sharks and afraid of shaky boats. Diego is just such a mishmash. With doubts and fears. He also makes mistakes. He is also tempted. And then he is wonderfully brave and independent, thanks to the 'bell'.


Personally, I really want a more sustainable earth. You process this in the book without being edifying. You literally show what happens when we want to be rich and powerful when we exploit the earth. Your disasters and your solutions are so fanciful and exaggerated that cause and effect become clear. And therefore linger. And why not eat mosquitoes when you are hungry?


At the same time you deal with discrimination, child abuse, the terror of the schoolyard and bullying in your book. And especially 'being different'. Again without being edifying. Without naming it. Just by the adventures that you experience extreme and imaginative characters. The hero becomes anti-hero and vice versa.


Your book is exciting, it is very difficult to put it away and not just read a chapter. Very nice that they are sometimes only two pages, then there can be just one.

Clara Wagtendonk, Kinshasa 


I liked my son very much and she liked it very much. If the next part is out, he wants to have them again.

Marcel de Wilde, Apeldoorn


Last Monday, my son discussed your second book in the classroom. He had made a beautiful presentation and told about it in smells and colors. Result, a class full of curious children and a 9 :).

Joy Lodarmasse (2), Beuningen


Did you read your 2nd book in 1 jug the day before yesterday? With a wood fire. We enjoyed the story until late at night.

Dirk de Jong, Ministry of Economic Affairs, biobased economy, The Hague


Hello Maurits when your new book comes from dingo sunstroke



Thanks for the audio book. Now I can listen to it when I am on my way. I also thought it was a nice book to read!

Mirjam Hooijberg, Edam


My son has devoured the books. My daughter is now busy in part three. In November she will hold a book review about Diego part 2. She is also very enthusiastic. That you have been at school with the children, they still like it very much!

Esther Zeeuw, Zeist


It was quiet here this afternoon. 2 children who were reading your book. So a success the purchase !!

Angelique churchyard, Baarn


My daughter (10) has proudly defended your books. She made a great impression with the reading and the posters. She got a 9. Thanks again!

Freek van Eijk, Bussum


dear Maurits.

With packet evening I got the '' sint '' '' Diego Zonnestek and the return of the eagle ''.

5 minutes ago I started reading.

And I wanted to tell you: I like it now!

When I'm half reading, I'll send a response with tips and tops.

I'm sure: this book will be a top book again! Together you go for a sustainable life.

For a long time I have been working on sustainability, and that makes your message in your books very clear.

hopefully you leave that in this and see your next books again!


Your writing friend

Fleur, Zeist


My daughter is very happy with your books

Helene de Nooijer, Castricum


My son (10) enjoys your books enormously!

Stephanie Schrama, Bergen


Our son is a big fan of your books. Well, it is a coincidence that he has to hold a book review at school (group 5) on 27 November. It would be great if he could take the writer of his book ... so if you happen to be in the neighborhood ;-).

Inge Ponte, Ulvenhout


Our son read the book with pleasure and last year (he was in group 7) his book review was held. We look forward to part 3.

Jeroen Teeling, Naarden 

My daughter is very enthusiastic about your books. She also wants the next part. Nice for her birthday. Can you give me the title?

Yvonne van der Velden, Leersum


We recently bought the book at the Jan Hekman school in Ouderkerk aan de Amstel after your visit in group 6B. I had been planning for some time to know how much fun our son enjoyed visiting his class. He immediately started reading that afternoon with enthusiasm, which had not happened before because he had serious dyslexia and reading is therefore a big task (frustration). Very nice to see that you have been able to enthuse him for reading!

Karien Verhulst, Ouderkerk aan de Amstel


book is already out and received positively

Desirée Jansen, Amsterdam


Part 1 is my daughter liked, just like part 2. We have bought part 3 this week and will also be nice.

Astrid van Alst, Zeist


My son (10) is very happy with your book!

Michel Leenders, Breda


My daughter has read part I full of enthusiasm and has now started on part II. Can I order part III and pre-register for part IV?

Hidde van Kersen, Huizen


My son reads your book with pleasure, we would also like to purchase the other one.

Theresa Werner, Rotterdam

According to my daughter "Really great fun!". Honor of your work!

Henk Goede, Volendam


My son found your book "super cool" and at the end of May he had his book review at school about you. Of course we want to have part III.

Frederique Hippler, Blaricum


 My son is very enthusiastic, also about part 2 (which is now at school :-)).

Marieke Bloemers, Breda


very nice

Mijntje van Berckelaer


Our daughter had already finished the book after a week. 'Very nice' was her reaction.

Ernst Knaapen, Castricum


My son has already published the first book and loved it !!

Cecilia Blacker - Sy, Amsterdam


Dear Maurits, thank you again for a beautiful book!

Marc van Kleef, Nijmegen


On Friday 17 April you will be guest at CBS De Burcht in Heerenveen.

I would like to have a signed book for our son (11) of both part 2 and 3.

Part 1 he found fantastic !!!

Ella Claus - van de Kolk, Heerenveen


My daughter enjoyed part 1 and 2. How nice that part 3 'comes along in such a special way.'

Margreet van Keulen, Muiderberg


I have read your books with pleasure and given away and / or recommended here and there.

Wim Diepenveen (47), Nijverdal


Your books are a great success with my daughter!

Yvette Hendrix, Nijmegen


Dear Maurits, you write beautiful books.

Sietske de Jong, The Natural Step, Joure

the book is very popular with us!

Pauline van Lennep, Aerdenhout


We are looking forward to part 4! My daughter thinks part 3 is just as fun.

Ken Korsmit, Doorwerth


I just ordered part 2 and 3 of the Diego books for our daughter. She is on her thursday as a Thursday and will be 10 years old. She has devoured part 1 and it fits her sense of nature experience and realization that we need to be clean on everything that we still have in the world. They also always fight fanatically for the Wnf so this was completely in her alley !!!

We would like to give her these parts for her birthday.

I hope you will save it!

Yvonne Nilessen, Wormer


Dear Maurits, my son (9) loved your first book, therefore also ordered this 2. Good luck with the last part!

Joop van der Valk, Odijk


Compliments for the book, my son is not a reader but you find books super.

Alice Knol - Rispens, Heerenveen


Let's all get on Diego's side!

Bill McKibben, Environmental Journalist of the Year according to Time Magazine, founder of 350.org


We have received the book 'Diego Zonnestreek & De Magische Bril' from you for our sons. They thought it was a beautiful book! My wife is now reading it by chance, and I have to tell her that it must absolutely be filmed.

Olivier Overweg


What my daughter of 10 writes: Hi Maurits, I have kept my reading circle about your book. I got a z / g (very good). that is the highest you can get. I found your book fantastic, and especially those ideas from the house of Amita. The best idea was that when you went to the bath, when you were done, all the hot water went to the heating. If you think up more of that kind of ideas, the world will look a lot more sustainable in a few years!

In short: a great, exciting, fun, humorous, ingenious book!

Caroline van Lankveld, Zeist 

Very satisfied. We thought you had a very nice low voice and that you read nicely. The children found a real writer to see present very interesting. The children have 'quarreled' who first read the book! And a quiz always works well with children. Nice questions, by the way!

Maria Schaeffer, 't Bontenest in Maarssenbroek


My son (11) is enjoying your books enormously!

Stephanie Schrama, Castricum


With this I would like to put a copy of part 3 in before ordering. My daughter (11) just finished part 2 and wants to quickly read part 3. Good luck with the completion!

Bob Vinke, Bussum


Book is very nice here! Can not say otherwise. And with a nice message too.

Iman Stratenus, Portugal


Very nice book. Meanwhile, read with my children.

Arnoud Six


Very good book Maurits! Nice how you processed the message.

John Oomkes, Haarlems Dagblad


Fantasy plays an important role in Diego Zonnestek ... but it is fantasy that touches reality. Maurits has made the wonderful forces of bacteria accessible to young and old in an inspiring, exciting and funny way. And that is a good thing, because bacteria can be of decisive importance in creating a sustainable society. Beautiful story with a nice plot!

Klaas Hellingwerf, Professor in 'General Microbiology' at the UvA, professor by special appointment in 'Physics of photoreceptor proteins', VU Amsterdam


Our compliments for the great book: fanciful and exciting to the last page. I have read it together with my 9-year-old son and he has now experienced for the first time what a "pageturner" is. Thank you for that. We will advertise you and recommend it.

Anneclaar Weijers, Kockengen


It was very nice! They all want to read the book, and I will read it in the group. It appeals to them for the imagination. I think this is really your target audience, because they love it!

Lies de Nijs, 't Kockenest in Kockengen


My son - 9 years old - found her very exciting and she read all three in one go. Very special, because he is - to our regret - not a reader.

Arnoud Oltmans, Bentveld


My son (11) and me and my husband loved it, both part 1 and 2 and part 3. My son did a book review about it! Compliments.

Brigitte Mohede, Naarden



Anita Zijlstra, De Telegraaf


My daughter thought it was a super fun, exciting and a bit funny book!

Karin Kammeraat


It was very fun. The children are all reading in your book, and bragging about each other at which chapter they are. And in the break your audio book will be listened to. Totally top, thank you!

Joliek de Boer, Montessorischool Zuid in Hilversum


The kids were so impressed by your reading. Silently they were listening with open mouth, so nice!

Leonie van Diemen

primary school de Scheper, Laren


Comment from my son of 9: When is the book diego sunstroke and the magic glasses 2 ready?

Quirine Heuzeveldt, Bussum


Self-written Comment from my son (9): A beautiful book and also exciting. It was pathetic somewhere in the end. "The sour twist" sounded nice to go often. It will be nice if a movie by Diego Zonnestek & the magical glasses would come. and it was a nice book.

Casper Beekman


When we went to the book presentation on the Malelande (primary school of our daughter) we made a joke that it was a smart salesman to sell your books. But after the presentation and especially after the reading of the first chapters of the book we were completely up. When our daughter was sleeping we took the book and secretly read it in a jerk. Next day confessed and now she reads the book herself. She is almost at the end and we can not wait for the next part ...

Arwen Isis Perlot, Amersfoort


My daughter (11) read them in one go!

Dietrich Loos


Read in 1 jerk. Nice exciting hopeful story, look forward to the next part full of anticipation.

Pim de Bokx, Boskoop


My daughter and I just finished Diego. She thought it was a great book. Very exciting, not only for her but also for me and my girlfriend.

Cees ten Thije, Amsterdam


My daughter has read all book five times ...

Peter Loomans, Roermond


My 9-year-old daughter loved it and has read all three books at once with me. She asked with big questioning eyes when a follow-up book came!

Freek van Eijk, Bussum


Am reading the book with my daughter: fun, exciting and instructive (My daughter thinks it is: 'heeeeeeeeeeeleel leuk')

Joost Ravoo, Haarlem


A wonderful book. I read it in one evening! My 7-year-old son is now working on it. It appeals to the imagination, with a message. Can not be more beautiful!

Feike van der Zandt-Bergsma, Eemnes


It was top and very successful!

Jeffrey Swerissen, The Bosberg School in Hollandsche Rading


I read it in quick speed. That happens when a book grabs you. Wonderful book!

Gerard Verweij, Alderman, Bussum


My 12-year-old son got the book Sunday and it's already gone. When will your next book be ready?

Manon Stok, Leiden 


We finally started reading. The children love it - and so do I. Let that Eagle return.

Cosmas Blaauw, Driebergen


I would not be surprised if this became the new Harry Potter!

Bert Homan, Alderman Utrechtse Heuvelrug


Our son read the book with pleasure and last year (he was in group 7) his book review was held. We look forward to part 3.

Jeroen Teeling, Naarden


Just read .. Congratulations! That's something to be proud of. If you do not want to save the world here, then I do not know.

Florian Andriessen, Terre des Hommes, Gouda


We liked it so much here. Entirely right!

Ariadne Biessels, Leersum


Thank you again very much for reading. Despite the snowballs against the window, the group has sustained it for more than half an hour! Compliments for you. At the end of the afternoon we talked about the magic glasses. It lives very much with the children. Fun!

Ria Schut, teacher at the OBB Blaricum


My daughter thought it was a very nice book. She enjoyed it!

Ineke de Jong


At the end of the day, I asked the children what they had liked most that day and your presence was at the top. Also my guest, Sara from group 5, came back in the classroom with a smile! So all in all, I would say so very successfully. We are looking forward to part III!

Jenny Medema, teacher group 5, primary school de Bolster Amersfoort


My nephew has enjoyed your book! When he finished it I got it on loan and I immediately read it. Very nice, I also enjoyed! I'm curious about the next part!

Emiel Schoonhoven, Amsterdam


It was very inspiring. Very enthusiastic, on behalf of all pupils and teachers! Thank you Maurits.

Els de Zoete, primary school Kaleidoscope in Almere


A few key words: Enthusiastic, humorous, empathic, excitingly read out and creatively concluded with a quiz. M.a.w ............... .. We really liked your input! We will continue to follow you.

Erik Moens, director primary school de Acaciahof in Middelburg


I hope you can look back with pleasure on your visit to the Maleland this afternoon. We certainly do! The children were enthusiastic and the parents thought it was a successful afternoon. And we as teachers see a lot of children fanatically diving into the bookcase and of course we are always happy with that.

Muriel van Burgsteden- Delahaye, teacher group 7 at De Malelande, Amersfoort


My daughter of 11 made a list at school with things to take to a desert island. And guess what books she takes with her? Indeed…

I thought it was great too!

Idgar from Kippersluis


I think it's a very nice book. I hope that many people find that with me.

Noud te Riele, The Hague


We look back with great pleasure to the day when you managed to bring the Wiekslag to higher spheres. By the way: the colleagues who read the book (or read it) found the book very good and look forward to the following parts. Good luck with writing.

Henk Blikman, director of primary school De Wiekslag, Tubbergen 



Book my son really liked.

Robbert Jan Voogt, Somewhere in Malaysia


Enjoyed your book. Delightful (compelling) fantasy with also a serious message. My son has read it in 2 days, was completely in it. We are waiting for the next part!

Alexis Fischer, Leeuwarden


A good book. And Maurits also did an excellent job as chairman of the day at our seminar!

Rob Schram, Director Cleaning Company Midden Nederland, Soest


Diego Zonnesteek is a great children's book, fascinating and catchy written with a sustainable message that also captures young children and encourages fun conversations. Recommended!

Teimen de Jong, Somewhere in Australia


I heartily recommend Maurits. He is very relaxed and calm in front of the class. The book is also very well received at school and is widely read. Even my son (no reader) from this group is still looking for a way to smuggle the book home to read it. Good luck Maurits! Give us a call when the next part is ready!

Ellen Huysmans, elementary school De Weidevogel, Amsterdam-Noord


I wanted to let you know how happy my daughter was with the book, she immediately took it to school to use it as a reading book in between! And what is very nice, the big font! Especially for children like my daughter, who are dyslexic, that is very nice reading! So my compliments.

Caroline Smit


Good story!

Coen Middelweerd, Haarlem


I do not know Maurits personally, but I would like to recommend him as a children's book author. The book about Diego Zonnestek & de Magische Bril is, in my opinion, a fun and fascinating story about a sustainable world. His way of writing will invite more children from 8 to 88 years to read the story at once, just like me. Recommended!

Harry Denis, Budel


P.S. a first reaction of a nephew of 11 years. He read the book in the same breath and asked when the second part came. He loved it.

Lonneke Oosterwijk, Huizen


Maurits succeeds in letting us fully enter the fictional world of "Diego Zonnestek", which shows that courage and innovation are essential to make the world a little better. The story cleverly uses tension and curiosity to introduce children to a playing field in which existing and new forces confront each other. A must for children, but also for anyone who wants to get inspired about the attractive presentation of a green world without falling into pleas.

Niels Bartels, Amsterdam


I really thought it was a good book. A lot of fantasy, exciting, fun. I can not say anything else.

Herman van der Werf, Naarden


We (my son of 10 and I) read it with pleasure! In fact, he told me the end .. (He could not wait until the next reading evening and he quickly read the secret himself). May it be clear that he too is very curious about the sequel!

Bob Roessink, Tilburg


Swanny is completely enthusiastic about your book, he is now reading on the couch: "exciting, fun, something for adults and children, very good story, no words."

Wim Salters, Haarlem 

My daughter thought part I was super cute and exciting at the age of six! Now she enjoys even more part II and III!

Petra de Hamer, Rotterdam


I think Maurits has delivered a good piece of work. The book is cleverly cast in the form of an adventure story. Very nice!

Erik Schroën, Weert


I can wholeheartedly recommend Maurits! He has read to us 120 children, and that was a big party. At 't Noorderlicht in Eemnes it was just such a success.

Jaap ter Steege, director primary school Rehoboth in Naarden-Vesting and the Noorderlicht in Eemnes and educational manager at Proceon Foundation


Message from my daughter (9): 'I found it a very nice book, very fanatical, funny and fun and exciting. interesting because you can write a whole book about a not so long story. And learned that if you do not take good care of the environment, it will not be good for the world. '

I really have nothing to whisper about. Nice to hear this again.

Jaap Logge, Doorn


My daughter (8) really devoured your book! Out in 2 days.

Maurits is an excellent writer or books that combines fantasy, reality and ambition for a more sustainable world. His series of books on Diego Heatstroke are both entertaining and showing the undiscovered and infant technologies in bioenergy and other sustainable technologies. His books are targeted at children; however adults, including myself, read it with a lot of fun. I can not wait for his next book in the series!

Erik Groen, Diemen


Diego's book has fallen well here.

Dirk Jan Emond, Purmerend


We are soooo enthusiastic about it. Great fun written books with a lot of imagination.

Sylvia van den Barselaar, Zwolle


Hi Maurits, have your book read out in a joke today. Brilliant!! I will definitely pass em to my cousins ​​!!

Thanks for this beautiful story! I look forward to part 2 ...

Vera Kamphorst, Dreumel


The books are a great success! My daughter of 10 reads them in no time. She wants to know when part IV comes out.

Michiel von Meyenfeldt, Vleuten


Comment from my daughter of 8: 'I thought it was exciting, funny, fun, everything at the same time! I've read it out in five days. "

Niels Mulder, Amsterdam


I have read the book during my holiday in Italy in 3 days. Totally awesome.

I read my last book at school because it had to. Then never again! (Now more than 30 years ago).

I am not a reader at all, but this story really appealed to me. My wife is reading the book now.

Ed Alting Siberg, Eemnes


Comment from a friend's daughter (10): "I liked the book so much that I read it in 5 hours in a row I'm already curious about the next book!"

Hugo Karelse, East Kapelle 

My daughter (9) likes it so much, she is reading it now for the second time!

Esther Kruyswijk, Bussum


Beautiful books. A great achievement! At the open day at De Meerlanden, Maurits handed out plenty of books, and that was a great success.

Angeline Kierkels, Director of the Meerlanden, Aalsmeer


Comment from my 11-year-old daughter: 'I found the book very exciting, too bad I had to sleep in between otherwise I would have read the book in a jerk!'

Mickey Bosman, Bussum


Comment from my son (13): 'You have very funny and fun characters. You think that if you write that book I also think it's a child because the book is written well in children's language and I really like that. I think it's exciting right from the start and the tension stays on all the time and that's why I read 30 pages every night. I especially like the end. "

Mischa Mirck - Meiland, Breda


Really nice to read. Good luck with finishing your next parts!

Floris Mokveld, Roermond


Comment from my son (11): 'I hardly ever read, but I really enjoyed this book! I saw it completely for me. It went deeper and deeper. I always wanted to read. Especially the end was very exciting. '

Personally, I found it very good too!

Joep Verboeket, Bussum


Magnificent! The story reads like a train. Wait for part 4 with tension.

Chris Bogaers, Laren NH


A story with a long shelf life which applies both to the age of the reader and to the story. Fun and imaginatively written. A topper in the category 'every night a chapter before bedtime.'

Matthijs van der Kaaij, Emmen


Exciting, funny, full of imagination. Diego is going for a beautiful green world, just like all of us.

Pieter Winsemius, former Minister of VROM (Environment)


Very nice. Also for adults!

Esther Schmidt, Amsterdam


 ... as if fate asked for it, the little ones came up with your book yesterday. I read for an hour - they did not want to stop! - and my daughter (9) then went on reading. She loved it!

Houdijn Beekhuis, Blaricum


Last weekend your book Diego Zonnestek gave to my cousin Suzanne - her parents read aloud - she is completely in the story and especially the magic and magic aspect works super! Aheum, also with me! Continue to make these beautiful things.

Tara Dik, Rijswijk


Exciting and educational. For children, but certainly not childish. The writer succeeds in avoiding "The Mine Field of Boring, Cursing and Mock." He succeeds in tempting children into a speedy race - because they all want to know as quickly as possible how it goes and ends. Compliments!

Maurits Groen, Founder Waka Waka, number 1 in the sustainable top 100 of Trouw


My two sons read it ... they were completely taken by the story! The oldest (10) has read a lot, so he knows a lot of books, but he really liked this!

Simon Morsink


Awesome! For young and old. More up-to-date and more important than ever.

Ruud Koornstra, founder Tendris


My 7-year-old son read it in one go and found it super exciting. A big compliment! That rarely happens to him.

Cora Zaaijer-van Muiswinkel, Middelburg


Comment from my son (11): 'I think you deserve a silver granger with this!'

Philippe Dony, Naarden


Comment from my son (11): 'Very nice ... a lot of fantasy. I read it in two days (on the ipad). '

John Nouwens


What I did not know about my daughter (9): "Every night my mother came and called out" Light! You have to sleep. "As soon as she left ... light on, read on!" My other 11-year-old daughter read it from my laptop and thought it was great! She read every night until late, unstoppable.

Wendela van Asbeck, somewhere in England


Comment from my daughter (12): 'I thought it was beautifully written and very nice. Especially Diego, and his whole development and that he discovers that he is actually very special, and what he is going through is really great to read. I also thought it was very funny. I am very curious about part II. '

Jef Hertoghs


My daughter (11) said this morning about the book: "It's like pieces of a puzzle, that's great to read."

Frank Serraarens, Rotterdam


I have read Diego Heatstroke & The Magic Glasses; It gave me the wonderful feeling of being a child again and forgot the 'mature' worries. Congratulations on this beautiful result. Look forward to the sequel. And then the movie ?!

Eldon van Rooijen, Heemstede


Comment from my daughter (9): "Wonderful book, really nice. I want to do a book review about this! "

Olivier Gorter


Really really nice. I normally read the gray hunter and I do not like Harry Potter and things like that and all that, but this was very funny and full of imagination and exciting and read nicely.

Daan (10)


Comment from my daughter (9): 'I thought it was super fun, funny, full of imagination, and sometimes very exciting. I read every night, and I really wanted to read. "

Aster Veldkamp


Comment from my son (12): "Super good. Really very good. "And my daughter (9) did a book review about it. What else do you want?

Carl van Suchtelen, Rotterdam


Super nice written!

Kirstin Gate


Comment from my son: "I had it in 2 days because the tension was unbearable. I thought it was better than Harry Potter. "

Joris Sibbing 


The book is fanciful and beautifully written and has exciting and instructive storylines. A children's book that I read with my daughter as an adult!

Gijs Meijer Swantee, Weesp


By reading this book I experienced that old-fashioned wonderful feeling of daydreaming. I have not read a book in ages, no time was my excuse, but that will change now! I liked it, exciting, surprising and addictive, I wanted to read it out.

Gerda Haverlag, Houses


My 9 year old son loves your book.

Gineke van Don, Nijmegen


There is even fighting for your books! In the fantasy games of the children, the entire world of Diego has already been given a place. Well done.

Isabel Lammerts van Bueren, Somewhere in France


My 10-year-old son has read your book with a lot of fun!

Joy Lodarmasse, Beuningen


I thought it was very good neighbor

Pieter Le Clercq, Somewhere in France


My daughter read the book last week, and she was very enthusiastic!

Reinder Schortinghuis


Hi Maurits the book was very nice and funny and very! very exciting. They were such weird characters Diego and Kala and amita and Zwam and Balthazar the best thing was that Amita had those cool stuff and the funniest thing was that Balthazar spoke so neatly and it was so exciting when his father was gone and what happened to him she father? For me the book was about a missing father and a very special child.

Son of Tarik Yousif, Amsterdam


Me, my wife and my daughter thought it was a very nice book!

John Kopp, Leusden


I absolutely thought it was a good book! Can not say otherwise

Mark Langens (32), Eindhoven


Nice written, good approach. I can recommend it to everyone!

Paul Stolte


Read in one breath.

Rita de Ligt - van der Zee, IVN, Zeeland


They are SUPER good books, we are waiting for more here at home Both son and daughter have read it in one go.

Pascal van den Bosch, Breda


Read with great pleasure my son Diego Zonnesteek. Magnificent! What a fantasy and beautiful language! Compliments! We are looking forward to part 3.

Martin van den Berg, Zwolle


What a wonderful story! My compliments.

Maurice Jennen, Hilversum


My youngest son loved Diego and is now looking forward to Part II!

Marsha Wagner, Zandvoort


Very nice. Read in one day. I'm curious about part III!

Nick van Rooij, Den Bosch


My son has had his book review about part I this year (successful!) And always asks when part II is released!
