I earn my living as a writer. In other words, as a magician, shaman, metaphorist. By chant and incantation—and with the active collaboration of my clients, the readers—I create images, characters, alternate realities in other minds. It is an ancient, venerable profession. All tribes have had storytellers, who wove legends round the campfire. My specialty involves epics not about long ago, but times and places yet to come. It attempts to weave realistic might-bes, and vivid might-have-beens. Above all, it is the literature of change.
