New York Times bestselling author Kay Hooper delivers once again with this chilling novel in which the Special Crimes Unit sends a Haven operative undercover to catch a charismatic killer who promises his victims heaven in exchange for more than their lives. . . 

Young, vulnerable, attractive, Tessa Gray looked like the perfect victim. Which was why Noah Bishop of the FBI’s Special Crimes Unit recruited the novice operative to use as bait for a killer hidden inside the Church of the Everlasting Sin–a fortified mountain compound where at least two women have already been murdered in ways that defy explanation. By entering the cult’s compound, Tessa will expose herself to the dark magnetism of its leader and his fanatically loyal followers. Once she’s inside, no one, not even Bishop or the town’s chief of police, can guarantee she’ll come out alive. And not even Tessa knows if she’s strong enough to resist the lure of a killer who is less than human.
