I'm currently reading Underboss.
Got to say, Gravano is a charismatic guy and I don't get the sense he is making himself out to be more than he was - granted I am only 70 odd pages into it.
If you read other books on the gambinos, you will see that many of the other members describe him much differently than he describes himself. They say he is greedy and that he lied to his boss to get permission to kill other members - just to steal their companies - and that he did that many times.
