I was looking through here, reading about the different books, and had a question. I got the book Cosa Nostra, History of the Sicilian Mafia, by John Dickie. I been reading it and it seems that the American mafia is thought to be different than the Sicilian mafia. Is there a book for beginner's that deals with the American mafia that anyone could recommend? Cosa Nostra is the first book I've read other than Mario Puzo's novels so I don't know much about anything other than what I read on here or look up online.
