Yes, it's a very good book. Thoroughly researched, well written, professionally sourced. But it comprehensively demolishes Sinatra the man in a way that leaves no room to hide. It portrays him as a violent, selfish, sex-crazed alcoholic who is thoroughly in bed with the Mafia. To a significant extent, this is all undeniable. The question it left in my mind was whether the book's portrayal is accurate and he really was a monster, or whether he was a flawed human being with these characteristics but in a less extreme and slightly more forgivable and understandable way - which shade of grey is it? Is this book a bit one-sided, or was he really a terrifically nasty piece of work who had people severely beaten up and who sexually assaulted at least one woman and harassed others? I don't know. But this book has somewhat ruined Sinatra for me. I love his music, but I think it will be a long while before I can stomach listening to any of it again.
