After fending off a would-be abductor, 27-year-old singer-songwriter Hannah Cassidy hides behind a car in the half-empty parking lot behind Pancake Pantry in Nashville. From there, she watches in horror as her attacker grabs another woman and pushes her into a nearby car. Within seconds, the vehicle speeds away.

TBI Special Agent Jake Matheson may have planned a quiet day off and a date with Shannon―the only name her online profile revealed―for an introductory lunch, but after pulling into a parking space on 21st Avenue South, he hears a scream. He races to the back of the building and finds a frightened young woman bent forward and gasping for breath.

Thrown together by uncanny circumstances and driven by the whys and what-ifs of secrets yet to be revealed, Hannah and Jake set out to find the connection between them before it becomes deadly.
