The author of the best-selling Harry Hole series now gives us an electrifying tale of vengeance set amid Oslo's brutal hierarchy of corruption. Sonny Lofthus has been in prison for almost half his life: serving time for crimes he didn't commit. In exchange, he gets an uninterrupted supply of heroin—and a stream of fellow prisoners seeking out his Buddha-like absolution. Years earlier Sonny’s father, a corrupt cop, took his own life rather than face exposure. Now Sonny is the center of a vortex of corruption: prison staff, police, lawyers, a desperate priest—all of them focused on keeping him stoned and jailed. When Sonny discovers a shocking truth about his father’s suicide, he makes a brilliant escape and begins hunting down the people responsible for his and his father’s demise. But he's also being hunted, and by enemies too many to count. Two questions remain: who will get to him first, and what will he do when he’s cornered?
