The Best Awful by Carrie Fisher

The Best Awful
288 pages; Simon & Schuster
Fisher is one of the funniest writers I've ever read. She lets you into the mind of a bipolar personality. There's a wonderful part where the main character stops taking her medication, and she's living in this amazingly happy world. Then you realize she's on a drug binge—she goes to Mexico with some guy she's never met before and ends up in a bathroom somewhere. I found her journey to be riveting, incredibly modern, and never self-pitying.
