Terry Brooks has been described as a master of modern fantasy, and tens of millions of readers can't be wrong. The first set of novels in his main universe are centered around the mythical sword Shannara, and the generations of men who wield it. A classic adventure fantasy, The Sword of Shannara is seen by many as a continuation of the Tolkein tradition – although there are a few who say Brooks follows his inspiration a little too closely.
Many have tried to adapt Shannara to the big screen with exactly zero success thus far. The latest comer was Warner Bros., who let the rights slip out of their grasp back in 2010. Perhaps someone could take a hint from Game of Thrones (which started out as a movie project) and sail for the long-form serialized waters of television. And if the series should last more than three seasons, there's plenty of material to draw from for a continuing story.
