Unstoppable is about a boy who is stuck in foster homes. He loves football, but has never played. When he gets a chance, his teammates call him unstoppable. Then a teammate out for revenge hits him in the knee. The doctor finds something wrong, something very wrong, when he gets the knee checked out.
This book is very good. It has a good plot, and tells some troubles of the teenage life. The boy is bullied, and also loves to fight. He is told to hold the anger back until he gets on the field. A lot of teens can probably relate to having anger towards teachers, parents, or even friends. I think that a lot of teens would like this book.
