Benny's Turn by Jared Wynn

Book Four in a series of six fantasy novellas that will forever change the way you think about Vampires, from the author of "Hey, Zeus!" and "Zen and the Art of Dying."

Katie McGuire wasn't very good at dying, and she didn't want to get better at it, either. All she wanted was to go back to the way things were, and if dying a second time was what it took to get there, she was willing to give it a try.

Of course if she did manage to go back, she would lose all her superpowers, and there was no guarantee that she would lose her enemies in return. But the only superpower she really wanted was the ability to kiss her new boyfriend, Benny, without tearing his face off and sucking his life out. He was willing to become a Vampire just to be with her, but she was willing to risk her very existence just to become mortal again, especially if it meant that Benny wouldn't have to go through the same experience.

But unfortunately...
