Diana London works hard in her day job as the city manager of a small South Carolina town. Yet she still finds time to moonlight for the Verdaville Police Department. As a werewolf. But while helping the police investigate a brutal murder, Diana discovers she's not the only magical creature in town. A female vampire has also decided to make Verdaville her murderous playground. What's worse, she has powers even Diana can't match. Fortunately, Diana is not the only one determined to stop her. Llyr Galatyn is the king of the Cachamwri Sidhe--a seductive otherworldly warrior with fantastic abilities. He's sworn to hunt down the murderer, and he's more than willing to give Diana any help she needs. And not just with the case. Diana is in her Burning Moon, a time of sexual heat, when need rides her hard. Llyr is delighted to be the answer to her erotic prayers. But as they hunt the vampire while desire runs hot between them, a deadly enemy urges the killer to turn her sights on Llyr. It seems Llyr isn't the only king of the Sidhe--and his brother wants him dead.
