Sunny McDonald is in the ultimate forbidden relationship. Her boyfriend Magnus is a vampire, and the leader of the Blood Coven. And when the Coven decides that Magnus needs a mate to be his co-ruler, Sunny's humanity puts her out of the running. The Coven's chosen candidate is Jane Johnson, a magna cum laude graduate of Oxford University who just happens to look like a vampiric supermodel.
Sunny is suspicious of a Rhodes Scholar who can't answer the most basic poli-sci questions, but Magnus brushes it off as petty jealousy. Still, when the Blood Coven goes to Las Vegas for a vampire convention, Sunny and her twin sister Rayne secretly tag along. And Sunny's not going home before she learns the truth about Jane. Because not everything stays in Vegas—especially bad blood.
