How to Fake-Date a Vampire

Faking it with a vampire duke should be simple, right? I've got one chance to prove to my coven that I'm worth my wand. But to do it, I'm going to have to make a deal with a vampire duke. I get to use his gorgeous estate in Cornwall to host the Beltane Ball--and in exchange, I'll pretend to be his girlfriend. But it's all a show for his grandmother.The rules of our fake relationship are simple: No flirting. No emotion. No sex. Simple, right? Except I can't seem to ignore the allure of the infuriating and devastatingly sexy vampire. Falling for a duke isn't an option, though. I would lose the anonymity that protects me and my coven, and that would ruin my life.
