Penumbra: Solstice — J. Rose Alexander

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.
