I keep carnivorous plants, including a Nepenthes I’ve had for many years. I used to post photos of my Nepenthes online, but a subset of men would compare the pitchers to genitalia. Which configuration of genitalia changed each time, but there were always comments, and I began to resent sharing my plant at all.

I had a lot of scraps of ideas that hadn’t coalesced into a story yet, and after a long enough period of agitating in my head, they all clumped together. For example, I had this idea of a tidal-locked water world whose only surface liquid water was on the side locked to its star. I liked the idea but couldn’t really get a plot to adhere to it.

There’s an established trope that magic can be dangerous if you don’t know what you’re doing, and I thought, what if I really push that? What if someone without the proper training is a live wire, shocking everything and everyone around them? In that case, you don’t want these kids to know magic until they are emotionally ready to control it.

Space is such a fertile ground for interesting world-building, and I thought this idea of characters living in asteroids to be a fascinating and also somewhat plausible world-building tool. I didn’t think so much of where to place them, so much as I knew where they would be based on the kind of people they are. I always think character first, and everything is in service to that.

I wrote the bulk of the first draft while I was on a cruise ship and experiencing the deep ennui that comes from being on a cruise ship. So that’s intrinsically buried deep in the DNA of this narrative in many mysterious and arcane ways. The second piece of inspiration is that a couple of years ago, on social media, I had seen an image of a mermaid in a bathtub with a bunch of tally marks written on the wall, and that painting really struck me. It’s always fun to take things seriously, and I started thinking about the sequence of events that might lead a person to keep a mermaid in a bathtub against its will, and the logistical challenges of essentially having both some guy in your house, and also a big goldfish.
