The Devil's Advocate by Gherbod Fleming

Savage madness seizes vampires worldwide. Relentless hunger gnaws, no matter how many drained, withered mortals litter the street.

Not since the Black Death has Owain ap Ieuan seen anything like the fatal disease sweeping across the world—but this time vampires are the victims. The anarchs suspect a plot by their elders. The elders blame the Sabbat who lurk in the darkest shadows. The Sabbat fear the return of the Antediluvians—and no one is ready for them.

There is opportunity in chaos, but Owain has long been the servant of many masters. As the Masquerade crumbles around him, whom will Owain serve? The Camarilla? The Sabbat? The Antediluvians? Or himself?

This is the first book of the new Blood Curse Trilogy, interwoven with plots and characters from the ongoing Grails Covenant Trilogy.
