Bite Club: Morganville Vampires, Book 10

Morganville is a quiet college town where humans and vampires live in relative peace. But lately a great deal of blood is being spilt... Having survived a number of adventures with her new night-dwelling friends, college student Claire Danvers has come to realise that for the most part, the undead just want to get on with their lives. But someone else wants them to get ready to rumble. There's a new extreme sport being broadcast over the Internet: bare-knuckle fights pitting captured vampires against one another, or, worse, against humans. Claire soon discovers that what started as an online brawl will soon threaten everyone in Morganville. And if they want to survive, they'll have to do a lot more than fight...
