The Morganville Vampires: Midnight Alley and Feast of Fools

Midnight Alley
Claire Danvers has pledged herself to Amelie, the most powerful vampire in town. But her protection doesn't offer much comfort when people start turning up dead and an ancient bloodsucker extends a chilling invitation for private lessons in his secluded home, giving a terrifying new meaning to "night school"...

Feast of Fools
The tenuous good-neighbor policy between the vampires and humans of Morganville is turned on its head with the arrival of bad-to-the-bone Mr. Bishop. What the ancient old-school vampire wants from the town is unthinkably sinister. It's only at a formal ball that Claire realized the elaborately evil trap Bishop has set for the warm-blooded souls of Morganville.
