Oh, it happens, and it’s horrible, whether it’s a book, a play or a short story. It’s like being in a maze when you can’t find the way out, and you keep passing the same point over and over again.
A fantasy setting is usually closer to the world as we know it than a science fiction one. It’s more accessible, and consequently more attractive to a child who is still awed by things that are all too familiar to an adult. Fantasy is unlikely to change gravity, or body chemistry, or a breathable atmosphere, so the creatures that populate that world would be at home in ours.
During my student days I hitch-hiked round Europe, getting as far as Istanbul and meeting interesting people, getting in and out of sticky situations, and becoming more and more hooked on other cultures, climates, scenery, wildlife. It’s only now I’m in my sixties that I’ve had the time and money to pursue my addiction – the gathering of exotic material for my writing.
