content: This is a great book about a thirteen-year-old boy named Mark. Mark is hiking across the desert where he stumbles upon a mysterious light. As Mark touches it he ends up in a whole new world. Grass and plants are red and animals are different. Also there are new types of humans. Now Mark must use everything he knows to survive and to find the mysterious light to get back home.This book has a lot of action in it and it keeps you wandering the whole time. That is one of the reasons I like this book. The only thing I didn't like is the book just kind of stops at the end. It is a great book though. I can compare this book to a lot of books Will Hobbs writes because they both have a lot of action. I could also compare this book to any survival books because Mark has to survive. I would recommend this book to anyone who likes Will Hobbs or loves action and adventure!
