She raced across the woods. Cold wind hit her face, and her heart pounded so fast she could almost feel the panic rushing through her veins. She knocked on the door knowing she didn’t have much time. Fear gripped her. “Please, help,” she whispered.

Rushing to the scene of a homicide at a farmhouse surrounded by thick, dark woodland, Special Agent Nikki Hunt is shocked to find four victims. A mother and father have been stabbed, their son, Bryce, is fighting for his life, and a young woman’s body is lying near the front door, her wrists bound with heart-shaped bunting. Nikki has never seen such a complex scene, but despite recovering from her own painful loss, she will do whatever it takes to bring this killer to justice.

Nikki soon identifies the woman as missing student Jessica Chandler and finds Bryce’s initials woven into the jumper she wore the night she died. It seems like they were a couple and that the Webers were a happy family. So who would want them dead?

The murders have all the hallmarks of a serial killer: All the evidence suggests the murderer was watching them, turned the security cameras off as they entered and fled the scene from the front door. But then Jessica’s friends tell Nikki she was uncomfortable around Bryce, and when two of Bryce’s friends go missing along Stillwater river and the girlfriend is found, she claims her boyfriend tried to kill her.

Are Bryce and his friends hiding a dark side? Nikki knows she must dig deeper to find out their secrets, but can she uncover the truth before the killer takes another life?
