I’ve always wanted to write a sequel to “Wednesday’s Story,” which ends with Wednesday, one of the personified Days of the week, having committed a crime. I wanted to follow up on that. On the consequences of her actions. But since the purpose of the personified Days is to tell stories, I knew I needed a story for them to tell within that larger story. I didn’t want to return to my old trick of using another reimagined children’s rhyme to frame the larger story around.

Despite being from a big family, I realized I hadn’t written many sibling stories, and I wanted to change that. I loved getting to explore the sisters’ relationship and follow how it changed and grew over the course of this story. The plot grew out of my suspicion of colonization stories, and of the assumption—still prevalent in more science fiction than I’d like—that there’s a non-problematic way to colonize. And, while I admire the ethos of “leave no trace,” I also wanted to explore its limitations.

This story had its roots in something I saw years ago, an article on the strangest things people had ever turned into New York Subway lost and founds. (Caveat: this story originated so long ago, that I may not even be remembering the details of its origin story correctly. Do you think I can turn a lost inspiration into a lost and found?) Anyway, I remember there being a lost and found snake.

I’m mixed Black/white, and grew up with many European fairy tales. I also have a lot of thoughts of my ancestors who were stolen from their homes and enslaved, and their cultures stripped from them, and that cultural knowledge lost for future generations—effects that I grapple with myself. So I identify very much with my witch, Agnes, when she says, “But this food, I made it mine, like House is mine . . . They don’t get to take it, too.” I’m making the European fairy tales and other trappings of colonialism that I’ve inherited one way or another, mine.
