Destroyer of Worlds — Jordan L. Hawk

After becoming possessed by the vampire spirit Gray, telekinetic Caleb Jansen thought his situation couldn't get any worse. But that was before Graham Forsyth, head of SPECTR's sinister Research Division, took him into custody.

Forsyth claims he can exorcise Gray before the forty-day time limit runs out. But once at RD, Caleb and Gray find themselves ensnared in a web of lies. What is the truth behind the tests Forsyth is performing on them? What does the agency really plan to do with Gray? And most worrisome of all, why does Gray sense demons within the walls of RD's compound?

Caleb's boyfriend, SPECTR agent John Starkweather, has suspicions of his own. With the help of his friend Sean and a shadowy organization known only by their symbol of a moth, John intends to save Caleb and Gray at any cost.

But when divided loyalties threaten his last chance at exorcism, Caleb discovers love may come at a price higher than he'd ever imagined.
