This book is sad, a bit creepy and kind of intense, definitely a little bit different than her other works. This book is about this boy named Brendan who is a foster child and has a miserable life until he builds a tree house in the forest and meets this green man. This story touches so many subjects like homelessness, depression, friendship and bullying. It has very short chapters and is a very interesting read. It is a good read for adults and children I think we can all get something out of this story.
