Being only half-vampyre in a school like Danny Gray's makes you a whole loser. But Danny manages to escape the worst of the bullying at his school. Thanks to genetic treatments he had as an infant, most people assume Danny's other half is human, not wulf. It's easy to pretend that his wulf-half doesn't exist, but lately every time there's a full moon he's been having strange symptoms. If Danny's fears turn out to be true, everything in his life could be destroyed. And with only a month until the next full moon, time is running out.
