Polly is running a fund raiser for the local animal shelter when she meets Vaughn, who wants nothing to do with what she's selling. Instead, he sends her to hell, believing she's a succubus.

But Polly's really a witch hybrid with a soul, and Vaughn's boss wants her alive. When Vaughn tracks her down again at the shelter, he discovers she's guarded by her faithful Corgi/Hellhound Sugar. Determined to get answers, Vaughn learns there's more to her than meets the eye, yet his resentment toward her grows until he discovers her ultimate secret.

Polly can't help her growing attraction to Vaughn, even if he's keeping something from her. As much as he doesn't want to protect her, he's forced to. Hell wants her back and will do anything to get her.
