This book is getting a 3 because it’s interesting. But it needs a LOT of help. It can not decide if it wants to be a picture book, a coffee table book, or a novel. I think it should be an illustrated novel. The idea is intriguing. The picture book format it is in now is too long to keep many readers attention, and for big sci-fi readers the world building has to many holes. Why do they have glowing marks on their arms? What are the fires and where did they come from? How can beetles lead someone to water? Even if it is kept in its picture book form, the world building needs to be addressed. There are pages that read like a high school assignment that would receive a C, maybe a C+ at best. The illustrations are colorful and help sell the concept but they do not fill the holes in the story. There are instances where it seems the author wrote himself into a hole, and pop, something happens. In the desert with no water. Pop, wake up next to a pool. Get stabbed by a tree, pop your friend is there their to help. The concept and the art are there. The story needs work.

The book revolves around Kai who dreamed to reach to greener world. The story was about his determination, his adventure outside park and things he learned on his way.

Characters-
Kai was very determined and strong character. His self-resistance and sticking to his goal was remarkable in the book. The boy was very friendly and had helping nature. A perfect character that could inspire children.

His friend RJ was content with what he got in park but as story progressed he realized his friend was right and he learned many things with him. In just few pages this book showed good development of this character. Loved RJ even more at the end.

What I liked-
The title of the book caught my attention, the Planet of Orb Trees. Isn’t that interesting? The worlds in the book was unique and different from all dystopian world I have read till now. It started with pretty good details about the world and the orbs, how it was important for everyone living in park and to Kai, why they were living in park and why Kai wanted to leave the park. Kai’s venture outside park also gave little more details about world.

He met interesting characters on his journey to maze. Greedy balloon boy made story even more interesting. With unique adventure book had great lessons for readers. It told about giving, self-restraint, taking only what you need and not to greed for more, showing kindness and helping those in need, following the dream, and friendship. I also liked the main theme of book environment and conservation of energy.

Easy to language and smooth to follow for children. Graphics of the book were colorful, creative and beautiful. Climax was exciting and end was great.

Overall, this book was with interesting dystopian world, strong characters and great messages that all children would love to read.

I enjoyed the premise of this post apocalyptic world where a group of people have taken refuge withing an amusement park. Kai, is not convinced that he is safe at the amusement park, he want to flee the flame-ridden planet to find a safe haven. Despite his friend's warnings he set out on a journey to get to the biggest Orb Three, because he is convinced that his escape lies in this three. 
In his journey Kai learns a lot of lessons about other people and about being kind. 
I did enjoy the story, but the story felt too rushed and it lacked any depth in its characters. The artwork was nice, but whoever was tasked with drawing a camel for this book does not know the different between a camel and a dromedary. Camel are two-humped, the drawing in the book is one-humped (that is a dromedary). As a children's book I believe that things like that should be on point, because these books are supposed to not only entertain children but also educate them. 
The book also had a few inconsistencies where there were talk about not having any coconuts and then suddenly the orbs were called coconuts. 
Apart from that it was an okay read.
