What would you do to keep your friends from falling into evil? It wasn't a question the group of friends at Ulysses Grant Regional High School wanted to think about. With Vincent trying to hide his werewolf side, Alia and Coray having to deal with the unanticipated news that they are witches, and Coleen getting slammed with the news she's adopted, they have enough to worry about. (Never mind Vincent's and Alia's crazy exes, Coray's mother, Coleen's father and all the magical creatures someone is sending after them to kill them. There was enough to keep anyone busy right through prom!) But the day Vladimir Vaduva shows up at their school, people start turning up both dead and drained of blood, and Coleen very nearly goes mad because of him, it becomes a question they have to have ask. As Rosa and Billy get pulled into the vortex, they realize they need an answer... And they have the feeling they aren't going to like it.

Facing down a vampire changes you. After dealing with all of the trials of their senior year, Alia Bronson and Coray Logan were hoping for a little less excitement before graduation. But, Mr. Berendorf, the newest history teacher in a long line of them at the high school, is a creep. More than that, he's an aggressive cretin who is determined to drive Alia away from her boyfriend. He's so confident Vincent Morchause is evil, he's willing to stoop to any level to get him out of the picture—including murder. What the mysterious Charles Berendorf doesn't realize is, he's not dealing with a typical high school student. Alia is the Princess Witch. When you mess with her loved ones, you mess with her. And when you mess with her, you are bound to regret it. Even if you have a vampire on your side.
