I read it at the bookstore ( I was too cheap to buy it) and found it informative. There's a lot of good info in there about the Gotti brothers and about the Gambino family. Charles Carneg speaks highly of his brother John; Charles sounds like a typical younger brother who idolized his older brother. He also says that Gene and John Gotti were two of the tougher guys in the neighborhood growing up. He says that they were pretty good with their fists and that they kept themselves in good shape and didn't smoke or drink much.
It's interesting to read that Charles, although he could be brutal and psycopathic, was a loving, caring son who looked after (and lived with) his elderly mother before his last arrest.
