I liked the book.Sammy gave us some good insights into his character and took us inside the Gambino's day to day life.

He took responsibility for most of his actions,and although he did occasionally downplay his evil side,it wasn't excessive.

He readily admits that his decision to turn rat was based solely on Gotti's intention to throw him to the wolves,and Gravano was smart enough to strike first.

I agree with those who feel that Sammy blew it in Witsec.He had it made and totally screwed himself.Reminds me of Jack Abbott and OJ. Both got a second chance and ruined it.
