The vampire king's army of vampire/werewolf hybrids is spreading across America, slaughtering everything in its path. Aided by Celise, a sprite driven mad by despair and armed with a book that grants unimaginable power, Cain's hybrids can strike anywhere and at any time. But the hybrids aren't the sprite's most powerful weapon. That distinction belongs to an innocent pack member, drawn into a web of betrayal by Celise's wicked lies. Already pressed on all sides, the wolves' allied forces must race to uncover a deadly secret being kept by one of their own. If they fail, even their combined strength won't be enough to stop the evil forces hellbent on nothing less but a complete annihilation of humankind. The hour of reckoning has arrived, and even the deepest love may not be enough to heal the wounds that come from within. The fate of the grey wolves hinges on their willingness to fight, forgive, and make unfathomable sacrifices. Contains mature themes.
