Hunters are a new breed of criminal. An aberration. Not human, not animal, but a terrifying combination.

After a long absence, forensic psychologist Walter Kirino is back with the Hunter Intelligence Division, on the trail of a new Hunter. Following the bodies that the Highway Snatcher leaves behind, Walter is forced to interrogate the question: where is the line between Hunter and human? To find out, he will revisit his traumatic past and throw open the rooms in his mind where his nightmares lay slumbering.
