Thirty years ago, the butchered body of a local Papago girl was found stuffed into a large cooler on the side of Highway 86. No one was ever charged for the crime. Few even cared.
And no one suspected it was just the beginning.
Retired Pima County Sheriff Brandon Walker's work with The Last Chance—an exclusive, nationwide fraternity of former lawmen investigating unsolved homicides—has brought new purpose to his life. But a gruesome, three-decades-old cold case is leading him into a strange world at the unlikely border between forensic science and tribal mysticism—a place where evil hides behind a perfect façade. A long-forgotten murder in the Arizona desert now threatens to bring home a new horror for Walker and his family, who have already survived the dark hunger of two human monsters. And suddenly the relentless ex-cop is the only person who can still unravel a blood knot of terror and obsession before the innocent die again.
