Firespell by Chloe Neill

Its not often that I come across something original in paranormal lit for teens, but Firespell is definitely one of these rare gems. Chloe Neill took the (almost) overused themes of boarding school, magic and vampires and twisted them around to tell the story of Lily Parker and the Junior Varsity.

Lily's parents have the opportunity to take a sabbatical in Germany, studying the papers of a famous philosopher. Rather than take their teenage daughter with them, they enroll Lily in St. Sophia's, an all-girls boarding school in Chicago. There Lily meets Scout, her self-proclaimed new BFF. But while Scout has taken Lily under her wing, the uber-rich-brat-pack finds every opportunity to antagonize the new girl. Typical boarding school stuff, really. But then one night Lily follows Scout as she sneaks out of their suite on a mysterious "errand." They descend into a series of tunnels under the school, and though Lily loses Scout, she learns enough to be afraid for her friend's safety.

Okay, I could say more but I'd be giving too much away. Read the book. Its great. Trust me.
