Elvis Cole and his enigmatic partner, Joe Pike, race to find a terrifying, unidentified killer in this twisting, unpredictable thriller from #1 New York Times bestselling author Robert Crais.

Traci Beller was thirteen when her father disappeared in the sleepy town of Rancha, not far from Los Angeles. The evidence says Tommy Beller abandoned his family, but Traci never believed it. Now, ten years later, Traci is a high-profile influencer with millions of followers and the money to hire the best detective she can find: Elvis Cole.

Elvis heads to Rancha where an ex-con named Sadie Givens and her daughter, Anya, might have a line on the missing man. But when Elvis finds himself shadowed by a gang of vicious criminals, the missing persons cold case becomes far more sinister.

Elvis calls his ex-Marine friend, Joe Pike, for help, and they follow Tommy Beller's trail into the depths of a monstrous, hidden evil. The case flips on its head, victims become predators, predators become prey, and the question becomes: Can Elvis Cole save them all from this nightmare?
