On a crisp September morning, while walking a bucolic woodland trail, Rina stumbles upon human remains once buried deep beneath the forest floor. Immediately, she calls her husband, Peter Decker, a former detective lieutenant with the LAPD now working for the local Greenbury Police. The body has been interred for years and there is scant physical evidence at the gravesite: a youthful skeleton, a skull wound, and long, dark strands of hair surrounding the bones. As Decker and his partner, Tyler McAdams, investigate further, they realize that they’re most likely dealing with a missing student from the nearby Five Colleges of Upstate—a well-known and well-respected consortium of higher learning.

And when more human remains are found in the same area, Decker and McAdams know this isn’t just a one-off murder case. Short-staffed and with no convenient entrée into the colleges, Decker enlists Rina’s help to act as his eyes and ears on campus. Winding their way through a dangerous labyrinth of steely suspects and untouchable academics, Decker, McAdams, and Rina race to protect their community from a psychopathic killer still in the area—and on the hunt for a fresh victim.
