War threatens the Four Lands, and Shannara's only hope lies in Penderrin Ohmsford, but it's a dreadfully slim hope. To save his world, Pen must restore his aunt, the former Ilse Witch, to her rightful position as High Druid of Shannara. But first Pen must free his aunt Grianne from the Forbidding: the world of the demons. To have the slightest chance of freeing her, he must find the mystical tree called the Tanequil, and somehow craft a talisman from its wood. But Shadea a'Ru, the treacherous usurper of his aunt's position, will do anything to stop Pen--and she has already captured Pen's parents and forced them to reveal their son's whereabouts. Sen Dunsidan, the monstrous Prime Minister of the Federation, has armed his greatest airship with a horrible new weapon. And Pen is just a boy, accompanied on his dangerous quest by only a Dwarf, a young Elf, and a blind Rover girl.
