You'd Better Watch Out — Tom Piccirilli

After his brutally violent cop father kills his mother in a heinous fashion on Christmas day, a young boy is raised on the streets of Brooklyn to become the deadliest hitman for the Mob. But even while he carves out a life and reputation for himself dispatching enemies of the syndicate, the hitter is planning his revenge against those who helped to make him what he is. From the cruel mob family to his own murderous old man, who sends threats and taunts from the safety of his jail cell. As the time approaches when his father will be free again, a Christmas nightmare of bloody retribution begins to unfold.

Employing the unique, darkly humorous, and powerful noir voice that is his trademark, Piccirilli once again demonstrates why he's become a must-read author for admirers of both crime and horror fiction.
