When Pia Williams, a gifted psychic medium, is contacted by the traumatized spirit of a young girl, her search to uncover the truth begins. The more Pia learns about the girl's gruesome fate, the more determined she is to bring those responsible to justice. But is she prepared for the shocking truth of what she's about to expose? With more questions than answers, one thing becomes clear to Pia: the girl's spirit is uniquely powerful, and she's killing from beyond the grave. Who--or what--is the girl now?

Accused of a murder the spirit commits, Pia reaches out to the only man who can help her: ex-Special Forces detective Nate Ryder.

As Pia and Nate are swept into an unpredictable situation brimming with dark, evil intent, they soon discover they have more to fear from the living than they ever did from the dead...
