Charleston, South Carolina is the most possessed city in the world. Evil thrives here. Something with which 30-year old exorcist Maria Abascal is intimately acquainted. She wrestles demons for a living. Especially Abigail, the one that lives within her. The one who feeds on damned souls and who's violated the laws of Hell to live on Earth - and live on, inside Maria. Now, as they work as one, Maria will discover how personal her battle with evil has become, and how far Abigail will go to protect them both. It's a journey where the unspeakable is just a heartbeat away.
