Yeah. I've read GOMORRAH. I also watched the movie of the same name, loosely based on the book. Pretty good, and a realistic portrail(As far as my reference points anyways) of what it is like for some of the lower level street guys in those organizations.

I am going to find a translation app or something and buy a few of these books and I'll post on what ones are good.

The movie A PROPHET is dope. Kind of an American version of CHOPPER or BLOOD IN, BLOD OUT. If you haven't seen it, see it. It is about an Arab kid who goes to prison in France and get pulled under the wing of a Corsican gangster. Good stuff.
