Six years ago the quiet town of Raven Hill in upstate New York was terrorized by a serial known as the Triple-6 Killer. After marking the doors of his intended victims, six days later they would be found dead, posed in a gruesome scene. After a sixth body was discovered, he disappeared, vanishing back into society. It was the story that Danielle "Dani" Cooper knew all too well. It was her friends he kidnapped and killed. When the police failed them, Dani and her friends took it upon themselves to hunt down the monster even though they were mere high school students. However, Triple-6 made it clear they were just kids playing pretend in his game of murder. As the sixth anniversary looms, Dani does all she can to distract herself, but Triple-6 returns to play a new game of murder with her. With no one to turn to, Dani reaches out to someone from her past, someone that understands her predicament all too well, someone brave enough to face the Devil himself - Elijah "Eli" Frost, her friend's half-brother. The problem is he is being hunted down by his own past. Together will Dani and Eli be strong enough to face their greatest fears, or will their pasts finally catch up to them?
