Double Dead — Chuck Wendig

In the Zombie apocalypse the last Vampire on Earth has a hell of time keeping his food alive.

Coburn's been dead now for close to a century, but seeing as how he's a vampire and all, it doesn't much bother him. Or at least it didn't, not until he awoke from a forced five-year slumber to discover that most of human civilization was now dead -- but not dead like him, oh no.

See, Coburn likes blood. The rest of the walking dead, they like brains. He's smart. Them, not so much. But they outnumber him by about a million to one. And the clotted blood of the walking dead cannot sustain him. Now he's starving. And nocturnal. And more pissed-off than a bee-stung rattlesnake. The vampire not only has to find human survivors (with their sweet, sweet blood), but now he has to transition from predator to protector -- after all, a man has to look after his food supply.
