Gavin Gregory often stares into the abyss - that's his job. An elite profiler at the FBI's Behavioral Analysis Unit, he hunts serial killers for a living. He knows how they behave, how they think, what motivates them. Considered the best at what he does, Gavin goes to investigate when it appears a dormant psychopath has reactivated. The case takes a bizarre turn when psychiatrist Debra Esteves contacts him and says she knows who the enigmatic killer is.
It soon becomes apparent that what she means is that she knows what the killer is.
But Gavin is a man of science, a rational man. Can she keep him safe from what is hunting him long enough to convince him she's right?
