Titanian Warrior - Titanian Chronicles, #3

One woman holds the key to his destiny-and his people's salvation. Hagen drags himself to the gates of Hell, body and soul shredded by the bloodlust that consumes all the unmated of his kind. Awaiting the painful atonement that will buy him ten more years to find his eternal mate-or face oblivion. But Hades himself kicks him out with the bloodlust still prowling, unsatisfied, in his veins. Bargained away by her parents to Master O, a mysterious, cruel wizard, Faiza serves in his household, keeping her small magic a secret, plagued by wild, confusing visions of a strange, suffering male.
Then the master brings home a wounded Titanian warrior whose touch sends ice, fire, and desire racing through her body. When she learns Master O plans to use Hagen as a weapon to conquer all races, she devises a desperate plan to free him-a plan that opens a portal to a world she's never known. And a destiny entwined with danger that could destroy them all.
