Hex Hall by Rachel Hawkins

Sophie Mercer is a witch. You know, black hats, and cats. Plus some mistakes...okay, a lot of mistakes. Which have landed her in Hex Hall, a reform school for others like her. Well, and some fairies and vampires. Not to mention the werewolves and other shifters.

By the end of her first day, Sophie knows she doesn't have any more luck at Hex Hall then she did in the mortal world. The three most popular girls in school hate her, she is crushing on one seriously hot warlock who happens to be way out of her league, and to make it all worse her roommate is a vampire that the entire school seems to hate.

Then things become even worse. Something is attacking students and Sophie's only friend is on top of the lists of suspects...in fact she is the only suspect. As the plot unfolds, Sophie realizes that not everything is as it seems and that her life is in danger.

Readers will love Sophie's spunk and daring in the first book of the Hex Hall trilogy. As the mystery unfolds it becomes clear that Sophie is at the center of a great web of confusion and danger. Page after page and chapter after chapter, readers will have trouble putting the book down. Sophie's story is engaging and exciting to read.
