Vampires Rule

They don't call him Jackpot for nothing. Ten years ago Jack escaped death when a vampire turned him. Now that he's grown tired of his fangs, a werewolf attack returns his mortality, but at what price? A fairy's mysterious diary claims he must kill the head werewolf before the beast builds an army. Jack just wants to be normal, but what's normal about a werewolf English teacher, a girlfriend who hunts werewolves after school, and a brother who can't decide if he should welcome Jack home or stake him to be on the safe side?
