Heritage of Shannara #1-4: Book Series by Terry Brooks
The 4-book set of mass market paperback novels includes the below titles:
The Scions of Shannara (ISBN 9780345370747): 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. When he accidently brings a mythic horror to life, a man calling himself Cogline drives it away. Cogline brings a message from Allanon: 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.
Thus continues the enthralling Shannara epic, a spellbinding tale of adventure, magic, and myth. . . .
The Druid of Shannara (ISBN 9780345375599): Ancient evil forces remain in control of the Four Lands. To restore the Kepp of the Druid Allanon, Walker Boh sets out on a journey to find the black Elfstone. After narrowly escaping death, he learns that the Elfstone lies in the hands of the Stone King. Now Walker Boh must venture into perilous, unknown lands with a strange band of fellow travelers that includes Morgan Leah, whose once-magic sword has been broken; Quickening, the daughter of the ancient King; and Pe Ell, an assassin who hatches his own dark, sinister plot.
The Elf Queen of Shannara (ISBN 9780345375582): “Find the Elves and return them to the world of Men!” the shade of the Druid Allanon had ordered Wren.
It was clearly an impossible task. The Elves had been gone from the Westland for more than a hundred years. There was not even a trace of their former city of Arborlon left to mark their passing. No one in the Esterland knew of them — except, finally, the Addershag.
The blind old woman had given instructions to find a place on the coast of the Blue Divide, build a fire, and keep it burning for three days. “One will come for you.”
Tiger Ty, the Wing Rider, had come on his giant Roc to carry Wren and her friend Garth to the only clear landing site on the island of Morrowindl, where, he said, the Elves might still exist, somewhere in the demon-haunted jungle.
Now she stood within that jungle, remembering the warning of the Addershag: “Beward, Elf-girl. I see danger ahead for you . . . and evil beyond imagining.” It had proved all too true.
Wren stood with her single weapon of magic, listening as demons evil beyond all imagining gathered for attack. How long could she resist?
And if, by some miracle, she reached the Elves and could convince them to return, how could they possibly retrace her perilous path to reach the one safe place on the coast?
Talismans of Shannara (ISBN 9780345386748): Although some of the goals to keep Shannara safe had been met, the work of Walker Boh, Wren, and Par was not yet done. For The Shadowmen still swarmed over the Four Lands, poisoning all with their dark magic. Each Shannaran had a special death waiting for him- at the hands of The Shadowmen-unless Par could find a way to free them all with the Sword of Shannara.
