A Vampire in Zombieland
You wouldn't like Coburn. People don't, as a rule. And that's okay, because he doesn't like people much either. People are food.
Five years ago, Coburn went to sleep—wasn't exactly planned—and he's just woken up to find most everybody in the world dead. Not dead like him; he looks human, drinks blood. He's smart. They're...none of those things. They outnumber him by about a million to one, and their clotted blood cannot sustain him.
Now he's starving, and on the run. He has to find blood, soon, and—like it or not—he's gonna have to keep an eye on the frail flesh-bags he finds it in. Time for the wolf to turn shepherd.
No, Coburn doesn't like people. But he'll have to learn to.
