A serial killer stalks a small town, and a police officer must face her family’s dark past to catch him.

The sleepy community of Kenorapeake Falls in northern Ontario seems like somewhere Constable Oaklynn Brock can finally outrun her violent past. That is, until she’s assigned to investigate a series of suspicious deaths. She can’t reveal that she knows how serial killers think because she grew up with one. Yet the eerie similarities between these murders and those committed by her father, known as the Suicide Slayer, hint at a copycat in their midst. But why here and why now?

Caleb Greene of the Canadian Watchers Squad, a special task force, has his own reasons to be wary of working alongside Oaklynn. But with rumors of a local cult known as the Light Paragons gaining power, the stakes are too high to refuse.

As they explore connections between the killings and cult, Oaklynn and Caleb are forced to confront old secrets…and a terrifying new threat. Someone is watching Oaklynn’s every move. They know exactly who she is and what she might be capable of. And soon her biggest fear isn’t just having her past exposed, but that a killer will turn whatever days she has left into a living nightmare…
