I’m a HUGE fan of found family, a group of people just deeply caring about each other, (mostly) no romance, just very I’ll-die-for-you close friendships. While found families will always be my number one favorite kind of relationship of all the possible ones, I also very much love sibling dynamics. One is very much related to the other of course, as I don’t just mean siblings through blood, but adopted and even just found siblings as well. The difference being that it just focuses on two individuals instead of a larger group. There is just something about stories that involve the relationships of siblings, and not gonna lie, especially when it’s complicated and messy.
Queer SFF featuring siblings
(note: books listed are queer and have siblings in them, but not necessarily both/all siblings involved are queer, and most stories aren’t *about* siblings)

When her sister Mari is kidnapped by The Fridge, a shadowy syndicate that holds people hostage in cryostasis, Eva must undergo a series of unpleasant, dangerous missions to pay the ransom.
But Eva may lose her mind before she can raise the money.

To free her sister, Eva will risk everything: her crew, her ship, and the life she’s built on the ashes of her past misdeeds. But when the dominoes start to fall and she finds the real threat is greater than she imagined, she must decide whether to play it cool or burn it all down.
Down Among the Sticks and Bones by Seanan McGuire
Twin sisters Jack and Jill were seventeen when they found their way home and were packed off to Eleanor West’s Home for Wayward Children.
This is the story of what happened first…
Jacqueline was her mother’s perfect daughter—polite and quiet, always dressed as a princess. If her mother was sometimes a little strict, it’s because crafting the perfect daughter takes discipline.
Jillian was her father’s perfect daughter—adventurous, thrill-seeking, and a bit of a tom-boy. He really would have preferred a son, but you work with what you’ve got.
They were five when they learned that grown-ups can’t be trusted.
They were twelve when they walked down the impossible staircase and discovered that the pretense of love can never be enough to prepare you a life filled with magic in a land filled with mad scientists and death and choices.

But when a deal turns deadly and Corvus returns from the war, Scorpia’s plans to take over the family business are interrupted, and the Kaiser siblings are forced to make a choice: take responsibility for their family’s involvement in a devastating massacre or lay low and hope it blows over.
Too bad Scorpia was never any good at staying out of a fight.

The Once and Future Witches by Alix E. Harrow
In 1893, there’s no such thing as witches. There used to be, in the wild, dark days before the burnings began, but now witching is nothing but tidy charms and nursery rhymes. If the modern woman wants any measure of power, she must find it at the ballot box.
But when the Eastwood sisters–James Juniper, Agnes Amaranth, and Beatrice Belladonna–join the suffragists of New Salem, they begin to pursue the forgotten words and ways that might turn the women’s movement into the witch’s movement. Stalked by shadows and sickness, hunted by forces who will not suffer a witch to vote-and perhaps not even to live-the sisters will need to delve into the oldest magics, draw new alliances, and heal the bond between them if they want to survive.
There’s no such thing as witches. But there will be.

Enter Julius Dax, online repoman and real-life thief. He’s been hired for a special job: stealing an unknown object from a reclusive tech billionaire. But when he finds out he’s stolen the first sentient AI, his payday gets a lot more complicated.

The Space Between Worlds by Micaia Johnson
Multiverse travel is finally possible, but there’s just one catch: No one can visit a world where their counterpart is still alive. Enter Cara, whose parallel selves happen to be exceptionally good at dying—from disease, turf wars, or vendettas they couldn’t outrun. Cara’s life has been cut short on 372 worlds in total.
On this Earth, however, Cara has survived. Identified as an outlier and therefore a perfect candidate for multiverse travel, Cara is plucked from the dirt of the wastelands. Now she has a nice apartment on the lower levels of the wealthy and walled-off Wiley City. She works—and shamelessly flirts—with her enticing yet aloof handler, Dell, as the two women collect off-world data for the Eldridge Institute. She even occasionally leaves the city to visit her family in the wastes, though she struggles to feel at home in either place. So long as she can keep her head down and avoid trouble, Cara is on a sure path to citizenship and security.
But trouble finds Cara when one of her eight remaining doppelgängers dies under mysterious circumstances, plunging her into a new world with an old secret. What she discovers will connect her past and her future in ways she could have never imagined—and reveal her own role in a plot that endangers not just her world, but the entire multiverse.

Into the Drowning Deep by Mira Grant
Seven years ago, the Atargatis set off on a voyage to the Mariana Trench to film a “mockumentary” bringing to life ancient sea creatures of legend. It was lost at sea with all hands. Some have called it a hoax; others have called it a maritime tragedy.
Now, a new crew has been assembled. But this time they’re not out to entertain. Some seek to validate their life’s work. Some seek the greatest hunt of all. Some seek the truth. But for the ambitious young scientist Victoria Stewart this is a voyage to uncover the fate of the sister she lost.
Whatever the truth may be, it will only be found below the waves. But the secrets of the deep come with a price.
I love that we have many (queer) stories available that include siblings who are also queer. It’s something I can’t even get enough of, just like good friendship and found family stories.
