I have an interest in understanding evil. Who is the bad guy - the vampire who kills people and sucks their blood, or the survivalists who kill people to save their own lives? Is evil merely a creation of people? Or is there an evil nature? Or is it in the eye of the beholder? I really like these questions.
About the time you might start to think that science fiction - the real stuff, not the species of fantasy that goes under the name - is really dead, along comes a story by Cory Doctorow.
I want my readers to be disturbed. I want them to ask, 'Could this really happen?' It is my job to think up new possibilities, to stimulate thought.
