I've been studying the mafia for 20 years. I have a calabrese (not sicilian) background, and this helps me understanding the guys. I really could not understand this book. The guy is crazy. He says Carlo Gambino is a coward, Salvatore Lucania knows nothing, Lepke and Lansky are not even mentioned! This is a tribute to his family. In his point of view his father is the real Godfather and only the Bonannos and the Profacis (his wife family) are cool, smart and traditional. I'll just tell you what, if this guy is right, everyone else is wrong! Lost of time and money! And just a tip, as far as I know, and all the world knows, the first cappo di tutti i capi was Lucky, and the next one Gambino.
