Cash is haunted by things. Hungry, hollow things. They only leave him alone when Heaven's beautiful reaper, Anaya, is around. Cash has always been good with girls, but Anaya isn't like the others. She's dead. And with his deteriorating health, Cash might soon be as well.
Anaya never breaks the rules, but the night of the fire, she recognized part of Cash's soul—and doomed him to something worse than death. Cash's soul now resides in an expired body, making him a shadow walker, a rare, coveted being that can walk between worlds. A being creatures of the underworld would do anything to get their hands on.
The lines between life and death are blurring, and Anaya and Cash find themselves falling helplessly over the edge. Trapped in a world where the living don't belong, can Cash make it out alive?
