The Morganville Vampires series by Rachel Caine
From the author of the popular Weather Warden series comes the debut of an exciting new series set in Morganville, Texas, where you would be well advised to avoid being out after dark. College freshman Claire Danvers has had enough of her nightmarish dorm situation. When Claire heads off-campus, the imposing old house where she finds a room may not be much better. Her new roommates don't show many signs of life, but they'll have Claire's back when the town's deepest secrets come crawling out, hungry for fresh blood. Will she be able to face the town's terror or will she drown like everyone else?
