It starts as a prank--a way to blow off steam after a long summer at Camp Horseshoe. Among the teen counselors, tensions and hormones are running high. No wonder the others agree when Jo-Beth Chancellor suggests they scare Monica O'Neal a little ... or a lot. Monica has it coming, and no one will really get hurt. What could go wrong? Everything. Twenty years later, Lucas Dalton, a senior detective with the sheriff's department, is investigating the discovery of human remains in a cavern at what used to be Camp Horseshoe. Lucas knows the spot well. His father, a preacher, ran the camp, and Lucas worked there that infamous summer when two girls went missing. No one knows what happened to either of them, though with a dangerous convict on the loose, gossip was rife that they may have been kidnapped, or worse. For Lucas, the case is personal--perhaps too much so. But it's time to uncover the whole truth at last. That's why seven former female counselors are coming back to the small Oregon town--among them, Bernadette Alsace, the woman Lucas has never forgotten. Each one knows something about that terrible night. Each promised not to tell. And as they reunite, a new horror unfolds. First some texts containing a personal memento and simple, terrifying message: YOU WILL PAY. Then, the murders begin. It started years ago. But it will end here--as a web of lust, greed, and betrayal is untangled to reveal a killer waiting to enact the perfect revenge.
