When I was about thirteen, a group of us went camping in someone’s cow pasture. There was a murky pond where we swam and fished. I waded deep into the dark, fish-reeking water, up to my throat, when my feet touched something sharp in the mud. I stepped back, but I found more hard edges, coated in slime. Probing around with my feet, horror and disgust broke over me when I realized where I was.

I backed a Kickstarter with a reward level that included working with Maurice on a short story. We’d both written airships, and I had friends who had lots of great things to say about Maurice as a person, so I thought that would be a fun experience. I was a little nervous, because a previous attempt to co-write a story didn’t go well. But that was a novel, and this would be a short story. I hoped that I’d have a better experience.

I love stories where characters find their person(s) through adventure, magic, and hardship. Before writing this story, I was also daydreaming epilogues for my favorite Hayao Miyazaki films. I thought, “What happens when the main characters grow old? What happens when one of them loses their partner in life? How do you process that grief when you’re jaded by the world and have magical abilities?” I was still processing my own grief and anxieties while writing it, and for a time I wasn’t sure how it would end.

SF is the only genre explicitly designed to explore the impact of scientific and technical change. The moment you posit a discovery that changes the way we understand Nature—human, biological, subatomic, what have you—you’re talking science fiction by definition. Those are the kinds of issues that interest me the most, and SF is the only genre big enough to explore them.

The Turnip is a re-telling of a fairy tale by the same name, which for my money is the single strangest story in the entire Grimm canon. The original Turnip has always been a source of fascination to me, because it is so clearly parts of two different stories cobbled together, and because one of those is clearly drawing on ancient Germanic mythology (the whole hanging-upside-down-from-a-tree-for-wisdom bit).
