The Glass Castle: A Memoir by Jeannette Walls
This is one of the most fascinating books I've ever read. It's the true story of the author's unusual childhood with parents who were intelligent and loving, but also eccentric, to put it mildly. They were often homeless, hungry, and "doing the skedaddle," which was her father's term for picking up in the middle of the night and fleeing bills and other responsibilities.
It's entertaining and easy to read, even when the stories are appalling. It's also thought-provoking on many levels. I coerced Jon into reading it after I finished. I could go on and on, but I'll settle for posting this right now, and if anyone wants to discuss, please comment. Highly recommended.
