Margaret Cunningham isn't your typical teenager. For one, she's well acquainted with the monsters that lurk in the shadows - well, most of them, anyway. Unable to aid her mother in hunting vampires, Maggie goes about rectifying the rather frustrating issue. As it turns out, her virgin blood works against her, its purity potent enough to send the bloodsuckers into a deadly and uncontrolled frenzy, and that's not good for anyone. Problem is, with little friends, and a small amount of social skills, the quest for "The Sex" may be the most difficult job yet.
