Feast of Fools - Rachel Caine - Paperback

The Morganville Vampires, book 4 of 15, completed series

It was hard to imagine how Claire's day could get any worse. And then the vampires holding her hostage wanted breakfast.

In the town of Morganville, vampires and humans have learnt to live in relative peace. Still, Claire Danvers knows that after dark, her homework can take a backseat to staying alive. But this tenuous harmony is turned on its head with the arrival of Mr. Bischop.

Bad to the bone, the ancient old-school vampire cares nothing about keeping the peace; staying at the top of the food chain is enough. What he wants from the town's living and dead is unthinkably sinister. It's only at a formal ball attended by vampires and their human dates that Claire realises Bishop's plan, and the elaborately evil trap he's set for the warm--blooded souls of Morganville.
