The boy on the cover of this sparse short book is Dylan, an Einstein-loving teen whose erratic and irrational mom kicked him out of the house on his 16th birthday.
Usually a good story shows how a character changes over time, but this story is shines by doing the opposite, chronicling Dylan's fight to stay whole and keep his dignity.
If you want to learn about (or better yet, teach someone about) the issues of homelessness, this realistic and heavily detailed novel is a good gateway to the topic.
Before you go out and buy the book, be advised it most definitely is from the Young Adult section, and it was almost too easy and simple a read.
