The Light Brigade by Kameron Hurley*

But something keeps going wrong with Dietz's travels; her memories don't match up with the mission briefs, as she experiences time itself turning in on itself. Is she going mad? Or are the things she's learning skipping through time the truth - and the war that's stealing her life the lie? A mindfuck of a book that's scathing in its critique of fascism and war. Features a sapphic lead but no romance.

A Psalm for the Wild-Built (Monk and Robot duology) by Becky Chambers

Novella. Long ago, robots, upon gaining sentience, simply laid down their work and walked into the wilderness.

In the 17 years since, he has wandered on his own, unable to either die or age, drowning his sorrows in drink and men.

As Hayes gets drawn deeper into the conspiracy - and his feelings for Yusuf intensify - he has to decide just how far he’s prepared to go to win the life and the love he wants.

When she was little, Bridge and her mother Jo used to play a game - one where they traveled to other worlds, inhabiting the bodies of their other selves. Now Jo is dead, and as Bridge is cleaning out her apartment she finds a strange device: a dreamworm, the very thing that supposedly makes inter-dimensional travel possible. Suddenly faced with the possibility that multiverse travel is real, Bridge is struck by a different question: could her mother still be alive? Scifi spiced with a healthy dose of body horror and some absolutely wild twists, Bridge also features a bisexual lead (however this is a blink and you’ll miss it moment) and a nonbinary co-narrator.

The Long Way to a Small, Angry Planet (Wayfarers series) by Becky Chambers

Rosemary Harper just got a job on the motley crew of the Wayfarer, a spaceship that works with tunneling new wormholes through space. With a past she wants to leave behind, Rosemary is happy to travel the far reaches of the universe with the chaotic crew, but when they land the job of a life time, things suddenly get a lot more dangerous. A bit of a tumblr classic in its day, this is a cozy space opera with an episodic feel and vividly realized characters and cultures. While pretty light on romance and focusing found family, there is a main f/f relationship.

An Unkindness of Ghosts by Rivers Solomon

Life on the lower decks of the generation ship HSS Matilda is hard for Aster, an outcast even among outcasts, trying to survive in a system not dissimilar to the old antebellum South.

Ninefox Gambit (The Machineries of Empire trilogy) by Yoon Ha Lee*

Military space opera where belief and culture shape the laws of reality, causing all kinds of atrocities as empires do everything in their power to force as many people as possible to conform to their way of life to strengthen their technology and weapons. It’s also very queer, with gay, lesbian and trans major characters, albeit little to no romance.

The Left Hand of Darkness (Hainish Cycle) by Ursula K. Le Guin

1969 classic. Genly Ai is an emissary sent to the planet of Winter, meant to help facilitate Winter's inclusion in a growing intergalactic civilization.

Too Like the Lightning (Terra Ignota series) by Ada Palmer*

Centuries in the future, humanity has deliberatly engineered society to be as utopian as possible, politically, socially, sexually, religiously. Written in an enlightenment style and featuring questions of human nature and whether it’s possible to change it, and what price we’re prepared to pay for peace, this book is simultaneously very heavy and very funny, and written in a very unique style. While still human, the society presented often feels starkly alien.

The Stars Are Legion by Kameron Hurley

This book fucked me up when I read it. It’s weird, it’s gross, there’s So Much Viscera, there are literally no men, it has living spaceships and biotech but in the most horrific way imaginable. Had I to categorize it I would call it grimdark military sf. It’s an experience but not necessarily a pleasant one.

The Luminous Dead by Caitlin Starling*

Possibly one of the most unsettling books I’ve ever read, and definitely the most claustrophobic. Gyre, a caver on an alien planet, ventures into the dark and dangerous underground, guided only by a woman who has no compunctions on using and manipulating Gyre as she sees fit to obtain her secretive goals down in the caves.

Escaping Exodus (Escaping Exodus series) by Nicky Drayden

While my feelings on Escaping Exodus were mixed, it cannot be denied that the dynamic between the two leads and the way they go from childhood best friends to enemies on different sides of a class and power struggle is very delicious. It also features some really cool worldbuilding of living, alien generation spaceships and the human culture that has developed inside them.

The Doors of Eden by Adrian Tchaikovsky*

The Doors of Eden is something of an experiment in speculative biology, featuring versions of Earth in which various different species were the one to rise to sentience, from dinosaurs to neanderthals. Now, something is threatening the existence of all timelines, dragging multiple different people and species into the struggle, among those a pair of cryptid hunting girlfriends and a transgender scientist.

Ascension by Jacqueline Koyanagi

Ascension follows Alana Quick, an expert Sky Surgeon who stows away on a spaceship in hopes of landing herself a job. But the ship and its crew are in deeper waters than she expected, facing threats emerging from a whole other universe, all of them searching for the same person: Alana’s spiritually enlightened sister. Undeniably a bit of an odd read, Ascension is also very creative and features polyamorous lesbian relationship.

Contagion (Contagion duology) by Erin Bowman*

Young adult. After receiving an SOS, a small crew is sent on a standard search-and-rescue mission. But what they find are not survivors awaiting help, but an abandoned site, full of dead bodies and crawling with something... monstrous. No romance, but features one sapphic co-lead and one who can easily be read as demisexual (however this doesn't show up until book two, which has more romance).

A Memory Called Empire (Texicalaan duology) by Arkady Martine

Mahit Dzmare is an ambassador sent to the center of the multi-system Teixcalaanli Empire, where she discovers that her predecessor has died. Trying to protect her home, an independent mining station, from being taken over by the empire, Mahit struggles to find out the truth of her predecessor's death while carrying the voice of his ghost in her head, guiding her as best he can. Light on the romance but does feature a sapphic relationship.

The Outside (The Outside trilogy) by Ada Hoffman*

AKA the book the put me in an existenial crisis. Souls are real, and they are used to feed AI gods in this lovecraftian inspired scifi where reality is warped and artifical gods stand against real, unfathomable ones. Autistic scientist Yasira is accused of heresy and, to save her eternal soul, is recruited by post-human cybernetic ‘angels’ to help hunt down her own former mentor, who is threatening to tear reality itself apart. Sapphic main character.

Dawn (Xenogenesis trilogy) by Octavia E. Butler*

After a devestating war leaves humanity on the brink of extinction, survivor Lilith finds herself waking up naked and alone in a strange room. She’s been rescued by the Oankali, who have arrived just in time to save the human race. But there’s a price to survival, and it might be humanity itself. Absolutely fucked up I love it I once had to drop the book mid read to stare at the ceiling and exclaim in horror at what was going on. Queer in the sense that the Oankali doesn't follow human ideas of gender and relationships, which is mirrored in their romantic relationships with humans. It is, however, pretty dark, with examinations of agency and consent, so enter with caution.

Remnant by Kate Genet

One day, Cass wakes up and finds everyone else is gone. Not dead, just gone, leaving her in a world which nature starts taking back with a dangerous, unnatural speed. But as she tries to survive this new normal, Cass realizes she may not be alone after all - but who else is out there, and are they a threat?

Young adult. Zetian is a citizen of Huaxia, where mecha aliens are constantly trying to breach the Great Wall. To keep them at bay, couples of men and women pilot so called Chrysalises, giant transforming robots. But the pilots are not equal - the women almost always die, sucked dry by their co-pilots.

Bonus AKA I haven't read these yet but they seem really cool:
