That is an excellent book. Definitely one of the more memorable books I've read. In fact, I probably remember more about that book than 95% of the other books I've read. For example, I'll always remember that Malcolm X would only sleep 3 hours every night. I could never do that. Gotta have a full night of sleep every night or I'm done.
Prepare yourself for the 50-100 pages where he talks about Islam though. That part was a major slog. And nothing to do with not being interested in what he has to say about Islam or anything, it's just written in a very dry way and drags on way too long. Besides that though, really, really good book.
