The Slap by Christos Tsiolkas

This book shows the radiating effects of one event: a man slaps another couple's child at a barbecue. Told from eight different points of view, and extending in time far past the initial slap, this book refuses to make any one of its characters into a villain, but shows them all as human, just as you think they couldn't possibly behave any worse (or that they couldn't possibly have been more wronged). I don't know that I'd care to hang out with this circle of people--mostly because there's a lot of what strikes me as gratuitous drug use--but the characters are well-realized, and the book works.
