Acheron

"Eleven thousand years ago, a god was born. Cursed into the body of a human, Acheron spent a lifetime of shame. But the strongest steel is forged from the fires of hell..."Acheron's human death unleashed an unspeakable horror that almost destroyed the earth. Then, brought back against his will, he became the sole defender of mankind. Only it was never that simple. For centuries, Acheron has fought for our survival and hidden a past he'll do anything to keep concealed. Until a lone woman who refuses to be intimidated by him threatens his very existence. Now his survival--and ours--hinges on hers, and old enemies reawaken and unite to kill them both. War has never been more deadly...or more fun.
