Callie was born under a bad sign. After checking out of her criminal ambitions, Callie has checked into a mental hospital to finalize her break-up with Mercer - the dead criminal who donated the heart that gave her a new lease on life, only to steal it back in a cross-country robbery romance. But after convincing herself he's not real, Callie has shaken her delusional beau and begun moving on when she gets a visitor: Mercer.
With a year left on her new heart, her world upended and her friends and family threatened by this real-life version of her dream boyfriend, Callie busts herself out and dives back into her life of crime. As she ties up her loose ends, Callie sets out to make peace with her past, figure out her future-and find a way to make this break-up permanent.
