The Absolutely True Diary Of a Part Time Indian
Sherman Alexie 

I would recommend this book for a book group. In fact, I think you should only read this book as a book group book. There are a lot of topics in the book that some people would not understand, topics that people would need some one to talk to about. In the book There are a lot of cartoons, some of them are confusing, so you might need someone to talk to, just to comprehend the content.

I think that would make a good movie. I think it would make a better movie than a book. There are a lot of places where Emotions and actual people saying the context, would really benefit to the movie.
