The woods are dark, deep, and deadly. Some places earn their bad reputation through tall tales or chance, but Grizzly Falls is different. Here, killers aren't just the stuff of legends and campfire lore. Someone is in the nighttime shadows, watching the local teens in the moonlit woods, waiting for the right moment, the right victim, and waiting to take away a life.

Detective Regan Pescoli is counting the days until her maternity leave. Exhausted and emotional, the last thing she needs is another suspected serial killer, especially when her daughter, Bianca, is swept up in the media storm. When a reality show arrives in town, the chaos only makes it harder for Pescoli and her partner, Selena Alvarez, to distinguish rumor from truth. Another body is found, and another. As the nightmare strikes closer to home, Pescoli races to find the terror lingering in the darkness.
