High Druid of Shannara #1-3: Book Series by Terry Brooks
The 3-book set of mass market paperback novels includes the below titles:
High Druid of Shannara: Jarka Ruus (ISBN 9780345435767): Twenty years have passed since Grianne Ohmsford denounced her former life as the dreaded Ilse Witch—saved by the love of her brother, the magic of the Sword of Shannara, and the destruction of her evil mentor, the Morgawr. Now, fulfilling the destiny predicted for her, she has established the Third Druid Council, and dedicated herself to its goals of peace, harmony among the races, and defense of the Four Lands. But the political intrigue, secret treachery, and sinister deeds that have haunted Druid history for generations continue to thrive. And despite her devotion to the greater good as Ard Rhys—the High Druid of Paranor, Grianne still has bitter enemies.
Among the highest ranks of the Council she leads lurk those who cannot forget her reign of terror as the Ilse Witch, who covet her seat of power, and who will stop at nothing to see her deposed . . . or destroyed. Even Grianne’s few allies—chief among them her trusted servant Tagwen—know of the plots against her. But they could never anticipate the sudden, ominous disappearance of the Ard Rhys, in the dead of night and without a trace. Now, barely a step ahead of the dark forces bent on stopping him, Tagwen joins Grianne’s brave young nephew, Pen Ohmsford, and the wise, powerful elf Ahren Elessedil on a desperate and dangerous mission of search and rescue—to deliver the High Druid of Shannara from an unspeakable fate.
High Druid of Shannara: Tanequil (ISBN 9780345499110): Dark magic has opened a gateway to the Forbidding and trapped within it Grianne Ohmsford, rightful High Druid of Shannara. Rescuing Grianne will be merely the beginning of the effort to return the Four Lands to some semblance of peace. Only her young nephew, Penderrin, has any hope of returning her to power. But to breach the Forbidding and bring Grianne back to the natural world, Pen must find the fabled Tanequil . . . and the talisman it alone can provide. That means journeying into the Inkrim–a dreaded region thick with shadows and haunted by harrowing legends. And there, Pen will strike a bargain more dire than he could ever imagine.
High Druid of Shannara: Straken (ISBN 9780345499400): The High Druid of Shannara trilogy draws to a thrilling close as a young hero nears completion of his trial by fire, a banished ruler fights for her life in a wilderness of dread, and forces of darkness and light square off in a battle unto death for the right to absolute rule. Prepare to be spellbound by the masterly hand of bestselling legend weaver Terry Brooks, conjuring at the peak of his skills.
For reasons known only to himself, the King of the Silver River has charged young Penderrin Ohmsford, barely more than a boy, with the daunting task of rescuing his aunt, Grianne, Ard Rhys of the Druid order, from her forced exile in the terrifying dimension of all things damned: the Forbidding. With the noble dwarf Tagwen and the prodigal elven princess Khyber Elessedil by his side–and with the outcome of the bloody war between the Federation and the Free-born at stake–Pen has accepted his mission without question. But not without risk . . . or sacrifice.
Because Shadea a’Ru, the ruthless Druid responsible for imprisoning the true Ard Rhys and usurping leadership at Paranor, has sent her agents and assassins in relentless pursuit of Pen and his comrades. And in securing the talisman he needs to breach the Forbidding, Pen has paid a devastating price. Now if the Free-born forces–already decimated by the Federation’s death-dealing new weapon–should fall, Shadea’s domination of the Four Lands will be assured. Nothing short of Pen’s success can turn the tide.
But Pen’s challenge grows greater when he learns that his parents, Bek Ohmsford and Rue Meridian, have fallen into Shadea’s hands. He must try to help them–but once within the walls of Druid’s Keep, where Shadea’s minions and dark magic lurk at every turn, Pen’s survival is far from assured. Yet it will all pale in comparison to the horrors that wait inside the Forbidding–horrors poised to break free upon the Four Lands when the time is right. . . .
