The Destroyer - Stargazer Series, #6

Mia Tallow has been taught to fear Stargazers by her ex-husband. However, she can't stand what his organization, the Stargazer Abolishers, stands for. Now she's on the run from both aliens and Abolishers. The best place to hide out is right under their noses, right outside of Realm, at a karaoke bar on the edge of town. Jace 1298 battles a virus that runs rampant in his blood. It makes him experience volatile rages, and like a modern-day vampire, he has to drink blood to dilute the effects.
He's everything regarding alien domination and violence that Mia's been taught. Yet, he can't resist stalking the sweet human female. Hell, if she's going to fear him, she may as well have a good reason.
