I'm reading "The Man Who Loved Books Too Much" by Allison Hoover Bartlett. Bartlett is a journalist who stumbles upon the world of rare book sellers and enthusiasts and finds out about a well known book thief who doesn't think he's doing anything wrong even though he keeps getting thrown in jail. He thinks it's unfair that he can't afford to buy these expensive books. It's broken down from interviews with the book seller who caught him and the thief himself.
Before this I read "An Expensive Education" by Nick McDonnell, a very good and very young (mid 20's author).
