Sacrifice — J.S. Bailey

Bobby Roland can't catch a break.

Less than a week after Bobby takes on the mantle of Servitude--a position granting him the ability to exorcise demons from the possessed--he finds an envelope taped to his door containing an intimidating note and a picture of a strange woman. When a shadowy figure is abducted off the sidewalk down the street from his house, Bobby can't help but wonder if it's her.
