Raised off the grid by survivalists, Mercy Kilpatrick believed in no greater safeguard than the backwoods of Oregon. Unforgiven by her father for abandoning the fold for the FBI, Mercy still holds to her past convictions. They're in her blood. They're her secrets--as guarded as her private survival retreat hidden away in the foothills. In a cabin near her hideaway, Mercy encounters a young girl whose grandmother is dying from multiple knife wounds. Hundreds of miles away, a body is discovered slashed to death in a similar way. The victims--a city judge and an old woman living in the woods--couldn't be more different. With the help of police chief Truman Daly, Mercy must find the killer before the body count rises. Mercy knows that the past has an edge on her. So does her family. How can she keep her secrets now...when they're the only things that can save her?
For FBI agent Mercy Kilpatrick, returning to rural Oregon has meant coming to terms with her roots. Raised as a prepper, Mercy is now relying on her survivalist instincts to defend her town from the people the law can't reach. But this time, an investigation calling up a dark past for her and police chief Truman Daly may be hitting too close to home. A rainstorm has uncovered the remains of five people, a reprise of the distinctive slaughter of two families twenty years ago. Except the convicted killer is in prison. Is this the case of a sick copycat or is the wrong man behind bars? One person might have the answer. The lone survivor of the decades-old crimes has returned to town still claiming that she can't remember a thing about the night she was left for dead. As the search for the truth becomes more dangerous, Mercy fears that the traumatized woman may not have buried her memories at all. She might be keeping them a secret. And there's a price to be paid for revealing them.
