When I first decided I wanted to be a writer, when I was 10, 11 years old, the books that I loved obviously and openly fit that description: They came with maps and glossaries and timelines - books like Lord Of The Rings, Dune, The Chronicles Of Narnia. I imagined that's what being a writer was: You invented a world, and you did it in a very detailed way, and you told stories that were set in that world.
