E-book extra: Neil Gaiman's "Writing and the Imagination."In the tranquil fields and meadows of long-ago England, there is a small hamlet that has stood on a jut of granite for 600 years. Just to the east stands a high stone wall, for which the village is named. Here, in the hamlet of Wall, young Tristran Thorn has lost his heart to the hauntingly beautiful Victoria Forester. And here, one crisp October eve, Tristran makes his love a promise -- an impetuous vow that will send him through the only breach in the wall, across the pasture... and into the most exhilarating adventure of his life.
