Enter Mercer, a mystery man who gets Callie s heart beating like crazy. As her behavior changes and their flirting deepens, Mercer reveals he s her heart donor. Only Callie can see, speak to, and touch him - and he s in love with her, a love she feels just as strongly.
A master thief when he died, Mercer offers to teach Callie his criminal ways and how to turn them against her old job and kick off a nationwide crime spree. Hunted by the FBI and popping heart meds to stay alive, Callie will find out that nothing s as scary as two people in love with nothing to lose."
