A shadow walks the streets at night. Stalking couples in their cars. Flashlight in one hand. Gun in the other. Killing people is so much fun.

When multiple murders terrorize a small town college campus, FBI profiler Violet Darger heads to rural Michigan to investigate. As soon as she arrives, a grim history begins to emerge.

The crimes have progressed steadily over a period of 18 months.

Indecent exposure to stalking.

Stalking to rape.

Rape to murder.

The UNSUB’s emphasis on power and control rapidly verges toward full blown sadism. He grows ever bolder, ever more vicious.

What could be more dangerous than a killer aroused by expressions of rage? Increasing brutality. Overkill.

Understanding his psychological motivations will guide the efforts to stop him.

Darger digs into the history. Tries to figure out how the perpetrator advanced unchecked to graver and graver trangressions.

What she finds buried in the police records unsettles her as much as the murders themselves.

While a faceless killer terrorizes the campus, the school administrators remain focused on burying the story.

The revelation creates another complication: The students feel disenfranchised. Angry.

Prostesters gather on lawns. Ignore the citywide curfew. An uprising brewing all over campus.

Darger must navigate an uncooperative administration, a powder keg of a campus, and a killer as savage and dangerous as any she’s ever faced.

When it all boils over, chaos descends on the townspeople. And the killer walks among them.
