I Know This Much is True by Wally Lamb

Wow! One of the best books I've ever read. It's the story of twins: one of whom is schizophrenic (Thomas) and the other who is not (Dominick). Despite his "normalcy," Dominick works very hard to be the victim. His shrink nails him on this, telling him he's the curator of the Dominick Birdsey Museum of Pain and Misery. The story deals with his fear of having his brother's illness and his journey to forgiveness of all those who have wronged him and it's a long list (894 pages worth). If you've dealt with a family member or friend with mental illness, I think this is a must read since we're not supposed to talk about these things. I also highly recommend Lamb's other novel, She's Come Undone.
