Forensic psychiatrist Kate Myers believes the killer of two teenage girls in Bigler County, California, is the same man who savagely murdered her twin sister over fifteen years ago. Working on sheer tenacity, she sets out to prove it.
Deputy Sheriff Ben Slater hides his personal pain behind the job, but Kate’s arrival knocks his world on its axis. He wants to believe her wild theory, but the idea of a serial killer with this pathology is bizarre. Together, they work to find a killer whose roots began in a small town in Bigler County, but whose violence spread across the nation. Soon, the Janus-like killer, more monster than man, fixates on Kate and wants nothing more than to kill her “again.”
