"Blame" by Michelle Huneven, is a fantastic work of fiction that reads like a true story. It's about a professional, everyday kinda woman who wakes up in jail after an alcoholic blackout, and is told that she killed 4 people the night before while driving drunk. I read this book while I was still drinking and it horrified me.
I agree that "Dry" is also a great book. I love Augusten Burroughs.
And yes, "Girl On The Train"!!!
