Midnight Alley by Rachel Caine
When Claire Danvers learned that her college town was run by vampires, she did what any intelligent, self-preserving freshman would do: She applied for a transfer and stocked up on garlic. The transfer is no longer an option, but that garlic may come in handy.
Claire Danvers's college town may be run by vampires but a truce between the living and the dead made things relatively safe. For a while. Now people are turning up dead, a psycho is stalking her, and an ancient bloodsucker has proposed private mentoring. To what end, Claire will find out. And it's giving night school a whole new meaning.
