Women in SF&F Month continues today with a guest post by Samantha Mills, plus a chance to win a copy of her upcoming book (whether you live in the US or not)! She is the author of the science fantasy novel The Wings Upon Her Back, a Compton Crook Award winner and World Fantasy Award finalist—as well as one of my own favorite books published in 2024 for its uniqueness and exploration of a variety of subjects, particularly its protagonist’s relationship with her mentor and the complications of walking away from her life’s work. Rabbit Test and Other Stories, her collection coming out on April 21, contains both fantasy and science fiction, including the eponymous winner of the Nebula, Locus, and Sturgeon Awards. I’m thrilled she is here today sharing about her experiences going from writing novel-length fiction to these stories with “Epic Worldbuilding in Short Fiction.”
About Rabbit Test and Other Stories:
This subversive debut short-fiction collection comes from one of the hottest talents in speculative fiction: 2025 Compton Crook Award and Pushcart Prize nominee Samantha Mills (The Wings Upon Her Back). The central story of the collection is Mills’s pivotal Nebula, Locus, and Sturgeon Award–winning story “Rabbit Test,” which interrogates the past, present, and future of abortion rights in America.
A time-traveling fisherwoman keeps landing on the right shore, but at the wrong time. A pair of witches fight over the gate between life and death. A new consciousness, intent upon seeing all the wonders of the universe, visits a floating library. A rock-and-roll legend squares off against a town full of devils. Humanity makes first contact but falters when put in charge of selecting the world’s representatives.
These riveting stories run the gamut of the genre, transitioning from fantasy to contemporary, and then into the farthest reaches of space. They take place in strange and emotional worlds, with stakes ranging from the epic to the personal, with ample room for humor and hope amid tragedy.
Epic Worldbuilding in Short Fiction
Samantha Mills
I learned how to write novels long before I learned how to write short stories. Book structure was imprinted on my brain after decades of reading, so while my first attempts were clumsy, at least the results were recognizably book-shaped! My first attempts at short stories, on the other hand, were complete failures. They were too long, they were too loaded with dialogue, and they didn’t have enough story. I was writing scenes that I would write for a book, with no chance of getting anywhere good before I ran out of pages.
It was worldbuilding in particular tripping me up, because I love fantasy. I love immersive settings, I love exploring the ramifications of speculative elements, I love big endings. So how do you get the feel of an epic without the length of an epic? In novels, you get however much room you need to fit however much plot you desire. A book can be 250 pages or 1,000. A story can span one book or a dozen. It doesn’t make them easy, but it does make them flexible.
In fact, I’d posit that one of the strongest tricks a novel has is sheer time spent reading. If you can entice a reader to follow your characters for several hundred pages, then even a simple ending can land with the weight of a long journey behind it. People spend hours, days, weeks immersed in the world of a book. They can spend literal years of their lives anticipating and engaging with a series. There’s room to breathe there. There’s room to indulge in detailed character studies, lengthy conversations, blossoming and evolving relationships, dazzling action set pieces or long, beautiful ruminations on anything really.
Whereas a short story is trying to evoke big feelings in ten to twenty pages, give or take. (Don’t ask me how flash fiction writers do it—they’re wizards!)
To write short fantasy, I had to learn how to be extremely judicious in my choice of detail. I had to learn to write montages and how to ruthlessly skip time. To my surprise, I realized that the brevity of a short story is exactly what gives it the potential to be read expansively. You can dive straight into the climax of a bigger story, and if you sprinkle in tidbits of backstory and worldbuilding in just the right way, readers will fill in the gaps on their own. Some authors have done that literally—the climax of Seth Dickinson’s debut novel, The Traitor Baru Cormorant, was first published as a short story, “The Traitor Baru Cormorant, Her Field-General, and Their Wounds.” It’s a great example of how the same epic story can be told in long form versus short form.
All of my study of short fiction came via reading. I discovered the online magazine Beneath Ceaseless Skies, which specializes in high fantasy with a literary bent. A goldmine of research and great fun! I discovered short story collections by authors like Catherynne Valente and Kij Johnson, and was dazzled by their structural experimentation and the beauty of their prose. Short stories were finally beginning to make sense to me as an art form almost wholly separate from that of the novel.
My big craft breakthrough was with a story called “Anchorage.” I had a good-sized cast of characters, a space crew visiting an anchoress walled up inside a floating library. To give it a more expansive feel, I wrote an extremely enthusiastic narrator who could gush about the many wonders they’d seen so far, sketching out a vibrant universe without ever leaving their small ship. I was learning to pack my sentences with detail and letting nothing go to waste.
Emboldened by that success, I wrote “Strange Waters.” It is about a fisherwoman who is lost in time, struggling to get home to her children. The story follows her many attempts to return to her original era. She haunts the same stretch of coastline for more than a decade, jumping forward and back, witnessing more than a thousand years of her city’s history. It’s a world that could fill a novel, but by keeping the narrative tightly tied to the main character’s quest, I could explore that world in a series of brief snapshots that, collectively, built up something bigger.
After that, I was fairly mad with power. I got more experimental with “The Limits of Magic,” a story about a women’s revolution in a fantasy world, in which the first half of the plot unspools in reverse, each brief scene going back in time through the main character’s life, until the thread snaps and the story moves forward again. I mashed science fiction and fantasy together with wild abandon in “Spindles,” in which a fairytale princess and her faithful bear fight an alien invasion. In “Rabbit Test,” I applied all of my techniques to the real world in another story spanning thousands of years, this time through the lens of abortion rights and pregnancy testing. And in “10 Visions of the Future; or, Self-Care For the End of Days,” I wrote a love letter to my husband which spirals out into all sorts of potentially catastrophic timelines when you’re living under a doomsday cult. (Clearly, I like to play with the element of time.)
I finally understood that if you have a hinge upon which to hang the story, some central throughline—a character arc, an emotion, a personal revelation, a point—then you can sketch as big a world around it as you want, purely through off-hand narrating. In the battle of show versus tell, you can get away with telling a whole hell of a lot as long as the parts you are showing are precise enough, evocative enough—as long as they make you feel something.
That’s the beauty of the short story, for me. It is different than a novel, where the journey is the point, and the destination is the reward for tagging along. A short story is the destination. It can be a dissection of a single moment in time, or it can be a whirlwind through all known history, but either way you are stepping in at the culmination point. Short stories are a beautiful collaboration between creator and audience, in which the author has a scant number of sentences to make their case, and the reader is asked to imagine the rest.
Between us, we dream up entire worlds.
