Magic Hunter: An Urban Fantasy Novel (The Vampire's Mage Series)

Rosalind’s mission is simple: hunt demons and mages. As a member of the Brotherhood, she’s dedicated to protecting the world from dark magic. Someone’s got to stop the supernatural bloodlust—plus, hunting’s a hell of a lot more exciting than her computer science classes.
Everything's going to plan until she meets Caine, a mage in league with the demons. He’s scary as hell and just as sexy. Worse, he's brought her a warning: rumors are spreading that Rosalind is a mage, too.
Now, the Hunters have chosen their next target—and it’s her.
To save her own life, Rosalind must form an uneasy alliance with Caine. But what if the rumors about her are true? If she can’t figure out who to trust, and fast, she’ll be exiled to the realm of the very demons she once hunted.
