You mean Tough Guy or one of his other books?

I have only read Tough Guy and its mostly about his life as a gang leader and eventually Gambino associate. Also a section of when he ends up in jail, I thought that was the most interesting part of the book - how he changed by reading and almost became an intellectual. Wouldnt rate it especially high as a "mafia book": his transformation as a person is the books usp in my opinion.
