Deputy Sheriff Nate Barrington is riding the crest of a new relationship. Kaitlyn Spencer is beautiful, altruistic, enlightened—everything he’s not. She teaches classes in New Age philosophy at her growing school. Nate doesn’t share her spirituality, but the physical passion hasn’t subsided enough for him to care.

Nate’s nirvana quickly unravels when Kaitlyn’s life is threatened on two separate occasions. With no apparent motive or any evidence suggesting collusion, the police are stumped. Even more troubling to Nate, Kaitlyn is convinced she is the target of unseen forces. Namely, a spirit assassin.

A hardheaded pragmatist, Nate isn’t prone to believe that spirits can possess people. As far as he’s concerned, Kaitlyn’s claims of perpetrators possessed by a spirit assassin are on par with comic book stories and have nothing to do with reality, and her esoteric, New Age mumbo jumbo begins to drive a wedge into their relationship. And why Kaitlyn? What secret is she hiding?

But when strikes continue from random, unwittingly manipulated people who haven't the remotest connection to Kaitlyn, Nate is forced to rethink his paradigm. Can an uncompromising realist broaden his mind in time to defend his girlfriend from an invisible enemy?
