On a hot summer's day in the sleepy American town of Rockville, Jessie Conway, a teacher at the local high school, notices a car driving slowly around the school grounds.
Twenty minutes later Jessie is fighting for her life and Rockville is plunged into living nightmare after a gun-toting student unleashes bloody mayhem.
For Jessie the horror is just beginning. Traumatized and hounded by the media she retreats to her home and tries to rebuild her shattered life.
Caleb Switch watches the developments in Rockville with interest. A skilled and diligent killer, his recent selections have disappointed him, offering challenge to a man of his predilections. Jessie Conway interests him: for she is no ordinary woman and a fine choice for a less than ordinary man.
As Jessie struggles to hold onto her marriage and her sanity she has no idea that she has become The Chosen.
