These days, romantic storylines dominate the market. While I enjoy them as much as the next person, as a writer I find myself more drawn to “friendmances” about the highs and lows of deep platonic friendships and, like in my most recent book, Saltcrop, stories about siblings.
Siblings can offer an interesting foil for the main character or be a source of information about the main character’s past. These are people with similar origins who developed under similar environmental factors, yet may still have ended up with very different worldviews, allegiances, and ways of life. How does that happen? And what does that tell us about who the main character is?
Siblings are often side characters, but my favorite kind of story is when the siblings are the one of the main characters, or even, sometimes, the whole point of the story. Take, for example, the classic quest for a missing sibling. Whether siblings love or hate each other, the familial bond can drive characters to do extraordinary things to rescue each other. And along the way, there’s ample room for discovery as a character is forced to confront how the person they love has changed in adulthood—and how they themselves have changed.
Siblings who grow up together are like intertwined trees: remove one, and its absence is still clear in the shape of the remaining trunk, and that absence is a space rich with mystery and tension. In Saltcrop, two sisters set out across a climate-ravaged ocean to find their missing sister, and in the process realize there are many things they didn’t know about her—or each other. But the thing about siblings is, it doesn’t matter whether you know the details of their current life, you would still go to the ends of the Earth for them.
Here are five science fiction and fantasy books that do the ‘sibling quest’ justice:
The Lighthouse at the Edge of the World by J.R. Dawson
This gorgeous Orpheus retelling by Dawson tells the story of a young woman, Charlie, grieving for her dead sister in modern-day Chicago when she accidentally follows a dog into the in-between place where souls wait to cross to the underworld. (Yes, a dog—the dogs in this book are as wonderful as the sister story.) There, in limbo, Charlie begins to hope that with the help of Nera, the daughter of the Charon-like ferryman, there might be a way to cross over to the land of the dead itself and rescue her sister. But at what cost? The story is gently devastating as it digs into both the little things that we remember about our loved ones and how losing a sibling can damage the structural integrity of a whole family.
Girl in the Creek by Wendy Wagner
Over on the horror side of the spectrum, another young woman, Erin, searches for her missing brother where he was last seen in the Clackamas National Forest. Before he went missing, they’d gone their separate paths in adulthood. Part of the mystery is not just finding out what happened to him, but also what he was doing out there in the first place. In the traces he left behind, she begins to get to know the person he’s become in adulthood. Oh, and the forest is inhabited by a sentient mycelial network both unnerving and enthralling, making the search urgent, dangerous, and all the more important. It’s also a great metaphor for the invisible strength of family relationships that drives the search in the first place.
Splinter in the Sky by Kemi Ashing-Giwa
In the Holy Vaalbaran Empire, Enitan is a scribe in an oppressed, colonized world managing to survive. When she returns home to find her sibling abducted, she’s forced to pack up her tea and travel to the capital itself to try to rescue them. The sibling quest is at the heart of this story, but along the way, Enitan gets drawn into a much larger conspiracy afoot in the rotten core of the empire. Ashing-Giwa masterfully depicts the broad and personal impact of subjugation and exploitation.
This Great Hemisphere by Mateo Askaripour
I love a dystopian novel, and this one is unlike anything I’ve read before: it depicts a future world where half the population is second class and literally invisible. This physical difference has sweeping social implications and makes the invisibles both the object of fear and disgust. Against this backdrop, Sweetmint, one of the invisible, learns that her missing and beloved older brother is both alive and the suspect of a major political assassination. Determined to find her brother before the state does, this novel is another great example of how you can love someone without really knowing them, and also how two similar people might end up different roads but still find themselves bending back toward each other in adulthood.
The Ones We’re Meant to Find by Joan He
Sibling quests have always been perfect for the Young Adult arena—they’re one of the most important relationships you have growing up. In this future world, the sisters are both searching for each other. The main character, Cee, is determined to find her sister Kasey—even when she has no memory of anything else—and sets out across the ocean to find her. Meanwhile, Kasey, a teen science prodigy living in a sealed city with a radical plan to save the Earth, is trying to piece together what might have happened to Cee. This novel is a journey through the complexities of family and in doing so explores the secrets we keep from each other and maybe ourselves.
