I read a fantastic book this week, A Million Little Pieces. It is a non-fiction account of one addicts' stay in rehab and it is one of the most gut-wrenching, heart-breaking and inspiring things I've ever read. It is actually an Oprah's Book Club recommendation and I bought it after seeing her rave about it. (Yeah, I watch Oprah. You just wish you could work from home and watch her too.)
It is written in a style that pretty much ignores most rules of grammar and punctuation, so it takes a bit of getting used to. But you do quickly get used to it and I laughed and cried pretty much every time I read it. This is such a powerful book I had to read it in small bits as opposed to just flying through it. The story isn't for the feint of heart, but you certainly don't need to be an addict to get something out of it either. I highly recommend it.
