Since the death of the Druid Allanon, the Four Lands have changed profoundly, with magic strictly forbidden in the Southland, now under totalitarian rule. Yet Par still has some power of the Wishsong. A message from Allanon arrives: venture to the dread Hadeshorn, along with the other Scions of Shannara. For in the future, all life in the Four Lands will be destroyed. To prevent this terrible fate, Allanon commands Par to recover the long-lost Sword of Shannara, a task that is next to impossible.

In this prequel to The Sword of Shannara, in which many details of the Four Lands' history are revealed, Druids, horrified by the misuse of magic, have eschewed it in favor of science. But Bremen the Druid studies magic, and becomes an outcast on its account. Bremen discovers that an invincible army of trolls are fast conquering all that lay to their south. Before them come the Nazgul-like Skull Bearers, disfigured and transformed Druids who have fallen prey to the dark arts.

Lifelong friends, they went their separate ways. Now they are together again, though each holds secrets from the others in his heart. They speak of a world shadowed with rumors of war.

Not until a chance encounter with a beautiful, sorrowful woman, who bears a magical crystal staff, draws the companions deeper into the shadows, forever changing their lives and shaping the fate of the world.

Now only the few who have survived the Labyrinth and crossed the Death Gate know of the presence of all four realms—and even they have yet to unravel the mysteries of their severed world. . . .
