The author of the internationally best-selling Harry Hole series now gives us an electrifying stand-alone novel set amid Oslo's hierarchy of corruption, from which one very unusual young man is about to propel himself into a mission of brutal revenge.

Sonny Lofthus, in his early thirties, has been in prison for the last dozen years: serving time for crimes he didn't commit. In exchange, he gets an uninterrupted supply of heroin—and the unexpected stream of fellow prisoners seeking out his uncanny abilities to soothe and absolve. His addiction started when his father committed suicide rather than be exposed as a corrupt cop, and 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, and all of them under the thumb of Oslo's crime overlord, the Twin. When Sonny learns some long-hidden truths about his father he makes a brilliant escape, and begins hunting down the people responsible for the hideous crimes he's paid for. But he's also being hunted, by the Twin, the cops, and the only person who knows the ultimate truth that Sonny is seeking. The question is, what will he do when they've cornered him?
