I've picked up my copy of of Sherman Alexie's "War Dances" and have already begun reading it. I love the idea of a community (city, school, neighborhood, etc) reading a book together. I really believe it helps to break down the walls that separate us and provides opportunities for us to see what we share in common. Heaven knows, we've gotten really good at tearing each other apart... to good at it.
