Dark Sacred Night by Michael Connelly
Often a long running mystery series gets tired, but Michael Connelly’s Harry Bosch novels are still fresh.
In Dark Sacred Night, Detective Bosch, retired from the LAPD, is working cold cases part time for the small town of San Fernando. While investigating a decades old homicide, he runs into Renee Ballard, a surfer and LAPD detective on the night beat. Initially wary of each other, the two team up to solve Daisy Clayton’s murder and voila, a new Bosch/Ballard series is born!
