The New York Times and Washington Post bestselling serial-killer thriller that will leave you wondering, is the past really in the past?

Three Chicago women have been found strangled, embalmed, and posed as if still alive. Doubting the findings of the local PD's profiler, The FBI calls on forensic psychologist Zoe Bentley to investigate.

Zoe quickly gets off on the wrong foot with her new partner, Special Agent Tatum Gray. Zoe's a hunter, intense and focused; Tatum's a smug maverick with little respect for the rules. Together, they must descend into a serial killer's psyche and untangle his twisted fantasies, or more women will die. But when the contents of three inconspicuous envelopes reveal a chilling connection to gruesome murders from Zoe's childhood, suddenly the hunter becomes the hunted.
