Losing

Wolf and Man, Goddess and Consort: they must remember who they are, lest they lose each other completely. Sachi and Addon travel into the deepest evil Addon has ever known to save the Center of the World from those who seek what is Sachi's, and Sachi's alone: Destruction. They will lose everything they hold dear, including their very souls, if they fail -- and if they succeed, Sachi must bring the End of Days -- or the Destruction of Destinies.

How can they keep each other safe in this hell when they can't even remember who they are?
