Kari Sterner lives two dangerous realities: An abusive husband gets closer to destroying her every day and seeing a serial killer's sadistic rampage through the eyes of his victims threatens her sanity. Unaware that the chilling hallucinations are actually real and hold the key to saving lives, she struggles to carry out the most important job of all...being a good mom to ten-year-old Adam. When her disturbing behavior and trail of undesirable clues warrant police suspicion, homicide detective Ryan Phillips is suddenly thrown into her quicksand world while trying to catch a brutal killer. A caring Phillips helps the distraught woman even though she is a suspect with unseemly knowledge of the murders. Dr. Lydia Braun is the only one who knows exactly what makes Kari so special. In a careless scheme to own and control her unprecedented supernatural ability, the psychiatrist crosses cold-blooded lines to prove an impossible, career-long theory: Cognitive time travel. Though Kari fears her gift and the doctor's misguided plan, she discovers more people will die unless she embraces it. After grating psychological deception, physical pain, and self-discovery, Kari finds the strength to accept her purpose and comes face-to-face with the blood-thirsty killer. She fights him with the only weapon she has...her mind.
