According to Libby, Riders of Rohan will contain three new books of the epic story, titled A Fellowship Endangers, Into the Riddermark, and the Third Marshal. He paints a few broad strokes about the writing process, and then goes into spoiler-heavy territory for those who like behind-the-scenes explanations.
The writer is excited to the point of needing sedation about finally entering this area of the books. "Rohan is a land that we knew we had to get right," Libby said. "For that reason alone, we've spent a great deal of time ensuring that we could do it justice. After all, the stretch of The Lord of the Rings that we have gotten up to is often cited as the favorite of readers and film-lovers alike. We need our version of the Riddermark to be equally as beloved."
