"I'm in trouble, Liz. I've uncovered something . . . They're watching . . . "

That panicked message on her answering machine is the last time Liz Ames hears from her sister Rachel, pastor of Paradise Christian Church in Key West, Florida.

Compelled to uncover the truth about her sister's disappearance, she heads to Key West. Within hours of her arrival a successful banker jumps to his death. Then a teenage girl whom Rachel was counseling is found brutally murdered. The ritualistic style of the killing is hauntingly similar to that used by the notorious "New Testament" serial killer — now on death row.

Could the teen's murder be related to Rachel's disappearance? Is a copycat killer at work? And why do the police refuse to help?

For answers, Liz turns to Rick Wells, a former Miami cop who worked the fringes of the "New Testament" investigation. Together they peel away layers of deception to reveal a terrifying adversary — and the unspeakable evil at the heart of this island paradise.
