Just read Havana Nocturne... I have to say I think I'm beginning to like TJ English' style.
English is a great writer. If you haven't already, check out The Westies. IMO its the definitive account of Coonan and Featherstone.
How detailed does Valachi go in his book about breaking down the families and family life?
Very detailed. At least in regards to how a low level soldier would see it. Certain editions of The Valachi Papers have a chart of sorts, which lists the early leaders of the Five Families and their affilaitions and protege's.
