Divine Hunter (The Vampire's Mage Series Book 4)
All’s fair in love and magic.

Rosalind is preparing for all-out war with Drew, who wields gods-magic with terrifying skill. But now Rosalind is learning to harness gods-magic, too. When she next encounters her cousin, she wants to destroy him completely.

Unfortunately for her, Drew launches a surprise attack on the vampire city. Torn away from Caine, she's trapped in Drew’s sadistic world where she has to do whatever he commands. But a quiet rage simmers under the surface...

Drew thinks he can control her, but she'll do anything to be reunited with Caine, her seductive demigod. And when she does, she's determined to learn the truth about him--and herself--once and for all. Gods-magic or not, she'll find a way back to the vampire city.

Because the price of failure will be far too high for her, for Caine--and for all of demon-kind.
