In Los Angeles in 1988, a 16-year-old girl was found dead with a single gunshot wound to the chest. Although detectives on the case found clues that pointed toward murder, no one was ever charged. Detective Harry Bosch, newly returned to the LAPD with the job of closing unsolved cases, gets the report of a new DNA match that makes the case very much alive again. A white supremacist with close ties to the LAPD becomes a suspect - but Bosch and his partner, Kizmin Rider, can't take a step without threatening higher-ups in the department. And the case turns out to be anything but cold. Everywhere he probes, Bosch finds hot grief, hot rage, and a bottomless well of treachery and danger.
