Probably more of a 4.5 but still...Wow. Insightful and grim and hopeful and dark, and so much more, all at the same time. I literally laughed and cried, occasionally simultaneously, while reading this book. A fascinating look through a teenager's eyes of his own reservation, his journey to a predominantly white school, the highs and lows of being Native American with the love and the alcohol and the stereotypes. He's a jaded 14 year old, with good reason, and yet finds it in himself to think about the larger world and his place in it. Excellent! 
 PS to add that I truly do not understand why this book is constantly on the most challenged books list. It's for teens and seems appropriate for that with much less sex, violence and language than expected/often seen.
