Hmm, that’s a neat idea (putting your characters in a different setting). Maybe you could do a sci-fi story that’s set in a medieval time period?
I just looked up the definition of speculative fiction because I kind of forgot. It’s “a genre of fiction that encompasses works in which the setting is other than the real world, involving supernatural, futuristic, or other imagined elements.” I prefer to think of myself as a speculative fiction writer (rather than a sci-fi or fantasy writer) because I don’t like to be boxed in. One writer that I really admire is Hannah Heath, who is a Christian speculative fiction writer. I haven’t read any of her books, but her plotlines are so outside-the-box, probably crossing across different genres and settings.
