Bewitching the Vampire. Brides of Prophecy, #9

The Lord Vampire of New Orleans meets his match in the leader of the local witch coven. Magic is returning to Earth, and Raina Callahan's witch coven is growing more powerful. She's been warned to be wary of catching interest from dangerous people, and sure enough, she discovers that someone is following her. Her stalker turns out to be the owner of a vampire-themed club-who really is a vampire. And although he is dead sexy and charming, Raina is not okay with his surveillance or his intent to claim her as his.
She will use every means of magic at her disposal to thwart him. Valentin St. Scarasse, Lord Vampire of New Orleans, has a weakness for voluptuous women with magic in their blood. Just when he has his sights set on what promises to be a delicious meal-and maybe a few passionate nights in bed-the Thirteenth Elder commands him to watch over the witch and her coven and keep them safe. But when Raina catches Valentin spying on her, the witch and the vampire embark on a battle of wills that will only end if they surrender to the heat between them. As the Evil One's cultists invade the city, Raina and Valentin must learn to trust each other and together, help their communities form an alliance that both sides swore would never happen.
