Parasite Positive

One year ago, Cal Thompson was a college freshman more interested in meeting girls and partying in New York City than in attending his biology classes. Now, after a fateful encounter with a mysterious woman named Morgan, biology has become, literally, Cal's life.Cal was infected by a parasite that has a truly horrifying effect on its host. Cal himself is a carrier, unchanged by the parasite, but he's infected the girlfriends he's had since Morgan-and all have turned into the ravening ghouls Cal calls peeps. The rest of us know them as vampires. And it's Cal's job to hunt them down before they can create even more of their kind. . . .Bursting with the sharp intelligence and sly humor that are fast becoming his trademark, Scott Westerfeld's new novel is an utterly original take on an archetype of horror.
