Good Books to Read While in Jail

My buddy got roped up on his 6th DUI and will be doing a pretty good stretch. I made this thread so I can get some good ideas for books to send to him while he is locked up these next few years. Anything that you think is a good read or self help kind of stuff would be appreciated. I'll be getting an idea of what he likes here soon but feel free to post anything that is good. I sent him book one of the Song of Fire and Ice series to see if he likes that as well as Outwitting the Devil: The Secret to Freedom and Success by Napoleon Hill.



Thanks in advance for the help!
