“ Writing a novel is a bit like being Daniel Boone. An author stands atop a ridge in a mountain range and can generally see a number of peaks in the distance. What lies between those peaks—the dales and glens, rivers, forests, and other features that distinguish one mountain landscape from another... is where the artistry and intrigue of the writing process lives. As the writer sets out into the story, leaving behind those high points—the beginning, a twist here and there, the climax, and, if perhaps a bit indistinct for the distance to cover, the end—entering the vale below, all manner of things can happen the writer never intended or expected at the onset. ”
