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.
