It's vampires vs. teenagers in this epic battle to stop graduation from turning into a bloodbath.
Caitlin's really, really smart and is class valedictorian. But she's also been acting really, really weird lately. So weird that Carly thinks she's a vampire. And not a friendly, high school vampire who just likes to sleep in, but the kind that wants to destroy all her classmates and turn them into an army of her undead minions. Can Carly and her friends stop Caitlin before graduation night? Or will they be doomed to live for eternity without a high school diploma?
