Brotherly Love by Pete Dexter

In the City of Brotherly Love, a car skids off the ice and ignites a chain of events that changes everything for eight-year-old Peter Flood. Peter’s father is a powerful man, a union boss with mob connections, but all the power in the world is useless to a grieving son. Raised by his uncle, Peter tries to distance himself from the casual brutality of the family business, gravitating instead toward a small South Philly gym. Peter’s cousin Michael—his “brother”—moves in another direction: into small-time intimidation and the trappings of a union prince. Neither, however, can outrun the logic of violence as they’re dragged into a world of bad blood and a chilling cycle of betrayal and retribution.
