Guys, can any of you tell me something about this book?

http://www.amazon.com/Mafia-Made-Easy-Anatomy-Culture/dp/1602472548

I'm mostly interested in the culture and mores of the Cosa Nostra and this book seems very interesting to me although it'll be really hard to find it in my country, so I just want to know if it's really worth the effort. Have any of you read it? Can you recommend it?
