Terry Brooks is one of my favorite authors. I love his books and stories.

Back Cover
Grianne Ohmsford, rightful High Druid of Shannara, is trapped in the Forbidding, a magical prison realm. The only one who can rescue her is her young nephew, Penderrin. To do so, Pen must find the mythical Tanequil, a tree whose wood can breach the walls of the Forbidding. But Shadea a’Ru, a traitorous High Druid, wants Grianne to rot there forever, and she’ll stop at nothing to eliminate Pen.
