When mild-mannered Casey Schwartz wakes up in jail, she has no memory of how she got there. But after her sister, Wanda, bails her out, Casey has more to deal with than a foggy memory-like abrupt mood swings and fireballs shooting from her fingertips. But things really head south when a vampire shows up on her doorstep... Vampire Clayton Gunnersson is seriously hot. And seriously taken--by a demon. In a ritual gone wrong, Clayton tried to get rid of his unwanted bond, but spilled some demonic blood on Casey, getting her possessed in the process. Now, Casey has to share her body and manage to keep her growing attraction to Clayton in check, because falling for her demon's boyfriend just might get Casey killed--from the inside out.
