If you want to read about Gotti during that period of time then I suggest "Mob Star" which I think was by Capici. I read it along time ago and enjoyed it,
I flipped through a dozen pages, it seemed quite good, like most of Capeci's stuff. Even though I know half the stuff it's supposed to cover I think I might read it sometime. For all his bullshit John was an interesting guy to read about... I even have a theory that he himself never pulled the trigger, he was probably in on a hit and that's it, then he got made and didn't have to be in on hits anymore.
