Unfinished Business was pretty disappointing. I found a copy online and downloaded it and read the first half until I got bored and put it down. He tried to fill it with stuff we already know, like the life of Casso and the Mafia cops. I expected more coverage of Massino flipping, etc and a lot more shit about the Bonannos but honestly in that book the Bonannos were the ones he was focused the least on.
