Hello everyone! Today I’m chatting about some amazing queer sci-fi books! We’ve got young adult, adult, space adventures, parallel worlds, and more! Sci-fi is a genre that’s hugely grown on me recently purely because of all these amazing queer releases, I just can’t enough! I hope you find something great to add to your tbr!
I want to point out I’m using the term Queer Sci-Fi to refer to any books that have multiple LGBT+ or Queer characters in, and give them the attention and detail they deserve.
On to the books!
Adult Sci-Fi Romance
While the Iskat Empire has long dominated the system through treaties and political alliances, several planets, including Thea, have begun to chafe under Iskat’s rule. When tragedy befalls Imperial Prince Taam, his Thean widower, Jainan, is rushed into an arranged marriage with Taam’s cousin, the disreputable Kiem, in a bid to keep the rising hostilities between the two worlds under control.
But when it comes to light that Prince Taam’s death may not have been an accident, and that Jainan himself may be a suspect, the unlikely pair must overcome their misgivings and learn to trust one another as they navigate the perils of the Iskat court, try to solve a murder, and prevent an interplanetary war… all while dealing with their growing feelings for each other.
If you love both contemporary romance and sci-fi, this book might be for you! It has all of the great swoon-worthy romance of a contemporary but in a sci-fi setting! This book gave me lots of squishy feelings, the romance between Prince Kiem and Jainan was absolutely adorable.
The first installment of the trilogy, Ninefox Gambit, centers on disgraced captain Kel Cheris, who must recapture the formidable Fortress of Scattered Needles in order to redeem herself in front of the Hexarchate.
To win an impossible war Captain Kel Cheris must awaken an ancient weapon and a despised traitor general.
Captain Kel Cheris of the hexarchate is disgraced for using unconventional methods in a battle against heretics. Kel Command gives her the opportunity to redeem herself by retaking the Fortress of Scattered Needles, a star fortress that has recently been captured by heretics. Cheris’s career isn’t the only thing at stake. If the fortress falls, the hexarchate itself might be next.
Cheris’s best hope is to ally with the undead tactician Shuos Jedao. The good news is that Jedao has never lost a battle, and he may be the only one who can figure out how to successfully besiege the fortress.
The bad news is that Jedao went mad in his first life and massacred two armies, one of them his own. As the siege wears on, Cheris must decide how far she can trust Jedao–because she might be his next victim
If a math lesbian and chaotic bisexual duo is what you’ve always wanted, it’s time to pick up Ninefox Gambit! While not necessarily an easy read this Korean-inspired space opera is fantastic. Also, an all queer cast!
This first book in a feminist space opera duology follows seven resistance fighters who will free the galaxy from the ruthless Tholosian Empire — or die trying.
When Eris faked her death, she thought she had left her old life as the heir to the galaxy’s most ruthless empire behind. But her recruitment by the Novantaen Resistance, an organization opposed to the empire’s voracious expansion, throws her right back into the fray.
Eris has been assigned a new mission: to infiltrate a spaceship ferrying deadly cargo and return the intelligence gathered to the Resistance. But her partner for the mission, mechanic and hotshot pilot Cloelia, bears an old grudge against Eris, making an already difficult infiltration even more complicated.
When they find the ship, they discover more than they bargained for: three fugitives with firsthand knowledge of the corrupt empire’s inner workings.
Together, these women possess the knowledge and capabilities to bring the empire to its knees. But the clock is ticking: the new heir to the empire plans to disrupt a peace summit with the only remaining alien empire, ensuring the empire’s continued expansion. If they can find a way to stop him, they will save the galaxy. If they can’t, millions may die.
Seven Devils is filled with Star Wars vibes and an amazing diverse cast trying to take down an evil empire. There’s an adorable sapphic relationship here that I loved! If you want your rebellion with a side of kickass women here’s your book!
Among the ashes of a dying world, an agent of the Commandant finds a letter. It reads: Burn before reading. Thus begins an unlikely correspondence between two rival agents hellbent on securing the best possible future for their warring factions. Now, what began as a taunt, a battlefield boast, grows into something more. Something epic. Something romantic. Something that could change the past and the future.
Except the discovery of their bond would mean death for each of them. There’s still a war going on, after all. And someone has to win that war.
If you want something that’s a little lighter on the technical sci-fi elements, This Is How You Lose The Time War is a beautifully written lyrical love story about two people on opposite sides of a war. This book is top tier sapphic goodness.
Odd-mannered, obsessive, withdrawn, Aster has little to offer folks in the way of rebuttal when they call her ogre and freak. She’s used to the names; she only wishes there was more truth to them. If she were truly a monster, as they accuse, she’d be powerful enough to tear down the walls around her until nothing remained of her world, save for stories told around the cookfire.
Aster lives in the low-deck slums of the HSS Matilda, a space vessel organized much like the antebellum South. For generations, the Matilda has ferried the last of humanity to a mythical Promised Land. On its way, the ship’s leaders have imposed harsh moral restrictions and deep indignities on dark-skinned sharecroppers like Aster, who they consider to be less than human.
Set on the HSS Matilda, a spaceship based upon the antebellum south this book is a dark one with heavy themes. The main character, Aster, is black, intersex, non-binary and autistic, alongside a cast who share many of these traits. I’d recommend you check out the trigger warnings for this one, but it’s a fantastic read if you’re in the headspace.
Young Adult Sci-FI
A thrilling adventure set against an intergalactic war with international bestselling author Charlie Jane Anders at the helm in her YA debut—think Star Wars meets Doctor Who, and buckle your seatbelts.
Tina has always known her destiny is outside the norm—after all, she is the human clone of the most brilliant alien commander in all the galaxies (even if the rest of the world is still deciding whether aliens exist). But she is tired of waiting for her life to begin.
And then it does—and maybe Tina should have been more prepared. At least she has a crew around her that she can trust—and her best friend at her side. Now, they just have to save the world.
This book’s a new release and it’s just so much fun! With all the geeky fun of Star Wars, Doctor Who and other sci-fi shows, a huge helping of found family, and loveable characters. The cast is incredibly queer and it’s also got sapphic friends-to-lovers.
Adult Science Fiction
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.
The Space Between Worlds is an excellent parallel universe sci-fi! It tackles some incredibly interesting themes in a lot of depth, with great social commentary on a lot of real world political issues such as class, race, privilege, and power. This book has some great twists and turns, and the conflict in the sapphic romance is deliciously angsty.
Adult Science Fiction
