What appears to be a simple crime, unmasks a chilling deception... Gin Crawford, the world's newest demon huntress, kills two minions who are breaking into a financial adviser's office. But what she thinks of as another night in the life of a demon huntress leads to a cover-up of epic proportions. A demon haunts her employer, the Agency, and only she can stop it. Aidan Smythe, her guardian mage and lover, along with her brother T, and the healer Eloise, join her search in discovering the demon's identity. A search thwarted by a powerful spell. Breaking the spell requires her to join forces with Zagan, the demon of deceit, the demon who marked her as his. But working together comes with a price. One Gin is not sure she can pay.
