There was nothing about this book that I didn't like. The narrator was good and the characterizations were strong and believable. I am Italian and this books shows the loyalty between mafia men, the fact that they have their very own moral code, which includes their drive to win at any cost. It also shows their softer side which is generally hidden from the outside world.
It was enjoying, if somewhat predictable. But since I really like this genre, I did like the story.
