This new series opens a new chapter in the Shannara legend. This is the story of the events before those described in The Sword of Shannara. Here begins the chronicle of the Great Wars and the destruction of the Old World, the story of how one world was destroyed and another created. This is the most ambitious project Terry Brooks has undertaken in his remarkable career, a series that will delight and amaze his existing fans and attract a whole new generation of readers.

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.

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.  

Despite denouncing her former life as the dreaded Ilse Witch, Grianne Ohmsford still has bitter enemies within the Third Druid Council.

Even Grianne's few allies know of the lots against her. But they could never anticipate her sudden, ominous disappearance in the dead of the night without a trace.
