Recently finished All American Mafioso: The Johnny Rosselli Story. Brilliantly written and well researched book. Lots of new information on Rosselli. Definitely one of the most interesting figures in the American Mob

Also read this one:

Supposedly written by a made man under a pseudonym, this gives you a revised history of the mob in NY. If it's legit, some good new info on the Gambino and Genovese families. Still only worth buying it on kindle though.
