The Witnessings are an integral part of their design, for only by redeeming the pain of every human who has lived and died can true Transcendence be achieved. Yet Alia discovers a dark side to the Transcendents' plans, a vein of madness that may lead to an unthinkable renunciation. Somehow, Michael Poole holds the fate of the future in his hands. Now, to save that future, Alia must undertake a desperate journey into the past. . . .From the Hardcover edition.
