The death of the fearsome Ögedei Khan has brought the Mongol invasion of the West to an abrupt halt. Exhausted, plagued by uncertainty and self-doubt, and reeling from betrayal by one of their own, the surviving Shield-Brethren struggle across a frozen, shattered wasteland to return home after their desperate battle in Mongolia. Their mission is complete--Christendom has been saved--but new and terrible questions haunt each member of the company: Are they heroes or villains? Or just pawns in a larger game, trapped in a world gone mad in the wake of the unspeakable devastation visited upon it by the Mongol horde? And most poignant of all, where--and what--is "home" now, and what will be their place in the world they fought to defend? Katabasis, a new novel in the acclaimed Foreworld Saga, follows the survivors as they struggle to confront their own fears and decide who they truly are--and whom they will ultimately serve.
