J. K. Rowling, author of the Harry Potter books I love so much, is my go-to person when I’m struggling with how to introduce a new and strange world of ideas that has only just emerged from my research. I imagine her telling me: New worlds are important, but you can’t just describe them. Give us the stories that make up that universe. No matter how wild and weird the new world might be, we’ll see ourselves in the stories.
