The Moth Diaries by Rachel Klein
A teenage girl who is sent away to boarding school after the death of her father chronicles her junior year in a leather-bound journal. She is obsessed with her roommate Lucy, who is in turn obsessed with Ernessa, the new girl across the hall. It quickly becomes apparent that there is something very odd about Ernessa, and Lucy begins to behave strangely as well, and then falls mysteriously ill. Our nameless narrator soon comes to believe that Ernessa is a vampire, which is never conclusively proven nor mis-proven. Is she? Or is it the fevered adolescent imaginings of the narrator?
For the vampire aficionado who is looking for something a more substantial than Twilight, ages 13+.
