In the college town of Morganville, vampires and humans have coexisted in (relatively) bloodless harmony...until the arrival of Bishop, a master vampire who threatens to put the evil back in evil undead and smash the fragile peace. But Bishop isn't the only threat....

Violent black clouds promise a storm of devastating proportions. As student Claire Danvers and her friends prepare to defend Morganville against the elements---both natural and unnatural---the unexpected happens: Morganville's vampires begin to vanish one by one. Discovering why leads Claire to one last choice: Swear allegiance to Bishop...or die.
