Celine Brennan should be riding the high of her recent promotion to detective, but instead she’s been saddled with a case no one can seem to solve with murders so gruesome others before her have quit. Not to mention, there’s something suspicious with a new club in town and her focus keeps being pulled from the case she should be devoting her attention to.

Zavier Lockwood is old. Three-hundred-years old to be precise and he’s bored because of it. Killing the scum of Chicago and cleaning up the streets since the cops can’t seem to do it is his favorite pastime. Until he lays eyes on Celine. Soon, he finds his obsession with her far more tempting than murder. After all, no vampire can resist the allure of their mate.

As their paths cross thanks to Zavier’s uncanny ability to be wherever Celine is they both come to realize there’s something far more nefarious going on in the city they both love. They’ll have to work together to get to the bottom of it, but what happens when Celine realizes the man she’s falling for isn’t only not human, but he’s the same one committing the crimes she’s supposed to solve?
