New York Times bestselling author Faye Kellerman delivers an electrifying crime novel of suspense as a young man's obsessive investigation into his sister's death draws him into the path of a sadistic serial killer.

Ben is now certain his sister was the victim of a sadistic serial killer, and refuses to let any distractions get in his way of bringing this monster to justice: not his rocky relationship with Ro, his rekindled friendship with J.D. or Detective Sam Shanks's constant warnings to butt out and let the police handle the investigation. But the ominous winds of Santa Fe are kicking up and there's nowhere left to hide. Find out what happens as Ben, Ro, and Detective Sam Shanks come head to head with the killer in the conclusion of Killing Season.
