CONTAINS A NEW EPILOGUE Mafia Prince is the first person account of one of the most brutal eras in Mafia history, Little Nicky" Scarfo's reign as boss of the Philadelphia family in the 1980s,written by Scarfo's underboss and nephew, Crazy Phil" Leonetti.The youngest-ever underboss at the age of 33, Leonetti was at the crux of the violent breakup of the traditional American Mafia in the 1980s when he infiltrated Atlantic City after gambling was legalized, and later turned state's evidence against his own. His testimony led directly to the convictions of dozens of high-ranking men including John Gotti, Vincent Gigante, and the downfall of his own uncle, Nick Scarfo,sparking the beginning of the end of La Cosa Nostra (the insiders' term for the Mafia, translated as This Thing of Ours").
