Retired LAPD detective Harry Bosch delves into the darkest chapter of his past in this electric thriller from #1 New York Times bestselling author Michael Connelly.

When Harry Bosch was 11 years old, his mother was murdered. He became a ward of the state, housed in MacLaren Children’s Center, a notorious facility where abuse was rampant. Decades after its closure, a lawsuit has resulted in a massive settlement for former residents. But when Bosch’s half-brother, defense attorney Mickey Haller, brings him word that he is entitled to part of it, Bosch says he doesn’t want the money. He wants justice.

The news awakens his memories of a place he had hoped never to revisit, and of a boy nicknamed Chops, a fellow ward who wound up dead. Bosch is certain that Chops was killed in a hidden space under the stairs --- the kids knew it as “the hollow” --- and his murder covered up. Now he is determined to reopen the investigation and learn the truth, even if the killer is long gone.

As Bosch digs into the files, he picks up the trail of a predator who not only survived, but went on to a life of vicious crime --- possibly including one of the city's most notorious unsolved cases. Forced to face a history that both scarred him and launched him on his mission as a cop, Bosch must bring down a sadistic criminal and finally put to rest the demons of his past.
