Family is at the heart of the Mafia. Justin Cascio uses genealogy to find new perspectives on the criminal organization's history, methods, and personnel. His first book, IN OUR BLOOD: THE MAFIA FAMILIES OF CORLEONE, is the culmination of years of research into the Mafia and mafiosi of his own family's ancestral hometown in Sicily. His second book, PASQUALINA: THE BOOTLEG QUEEN OF SPRINGFIELD, MASSACHUSETTS, is the true history of the Mafia gangs of western Massachusetts during Prohibition, and the woman who ruled over them.
