My own writing has perhaps more of an American flavor than a British one, but that's because the stories I've so far written have needed it. 'Empire State,' 'Seven Wonders' and 'The Age Atomic' are all very place-centric, where the setting itself is almost a character. But there is a universality to story that isn't just limited to science fiction.
Even as I was writing 'Empire State,' I knew there were more adventures for the main character, private detective Rad Bradley, to have. I also knew that the world was far larger than what I'd presented in book one.
That's the most amazing thing about writing, whether it's in prose or comics: that you can create something from nothing, and suddenly they come to life, like they've always been there.
