You’ve been excited about this getaway for months–at last, a chance to reconnect with your husband at a secluded island resort. But when he unexpectedly calls you from the beach, you hear the urgency in his voice. Something is very wrong. The beautiful waitress from the restaurant last night has been found lying dead in the sand. And the police want to question your husband about it.

She's a con artist who erases herself to become whoever you need her to be—a college student. A life coach. A real estate agent. Nothing about her is real.
