I read the Philip Carlo book on Pitera. It was Ok. But after learning more about Carlo and his BS it tainted my view of that book I think and made it hard to believe anything that was written.
I thought leonetti's was one of the best I read along with the one written about the rizzuto family called business or blood, it was also very good in my opinion and worth reading. Very long but I finished it in 2 evenings.
The quiet don I never finished. So slow and boring and convoluted and focused more on material that was not of interest or about the boss himself.
DiDinato's book I read and it was Ok. I'd give it about a 6.5 out of ten. Hard to know what to believe. But it gives insight into the life of an average made guy in the 90's - 2000's. And it was not so boring or uninteresting you could not read it , like the quiet don was.
