The most recommended space opera books

To Sleep in a Sea of Stars is a bold, futuristic epic that immediately sucked me in and wouldn’t let me go. Starting on the far-off world of Adrasteia, the story follows Kira across the galaxy after she mistakenly walks into an interstellar war. Paolini perfectly paints this fantastical story, leaving you desperate for more. Having read Eragon at a young age, I wasn’t expecting Paolini to write this genre, but I am so impressed by his work. While I’d recommend any of his books, To Sleep in a Sea of Stars is my new favorite. His world-building is amazing and wildly entertaining!

When I received Ninefox Gambit for Christmas, I have to say that I was blown away. What I loved the most about it wasn’t just that Yoon Ha Lee dropped me in the middle of a war and hit the ground running (from lazer blasts!) The tactician Shuos Jedao leads Cheris into an inner battle that turns out to be even more consequential than the war itself. And when finally the question arises of “who is right” in the conflict, something that the good soldier Cheris has never asked herself before, the answer depends on who’s answering. Cheris, like all of us, must decide for herself whether the secrets of Jedao’s past are true, or whether she’s having her strings pulled.

CJ Cherryh is a master at delving into the psychology and societies of her characters and making the reader feel what they feel.

The Chanur books, starting with this book, are a standout example of alien fiction because they’re told almost exclusively from the point of view of Captain Pyanfar Chanur, a cat-like member of the Hani. She’s smart and tough, which is what you need to be when hauling freight through Compact Space, home to seven very different alien species.

Caught in deadly political intrigue, Pyanfar is forced to figure out what the aliens opposing her are thinking and how they are likely to react to any move she makes. As readers, this brings us in close for a detailed consideration of these alien species, all set against a deadly game of cat and mouse and a dash to find safe haven across many star systems.

This book is… show more.

In this novel, human beings have been nearly wiped out and scattered throughout the galaxy when a drug derived from our unusual binary brains becomes the most sought-after recreational narcotic in the universe. 

One human woman and her ragtag crew might be able to save the human race—so long as she can keep straight which reality is real: the one where she plays the hero, or the one where she’s the victim.

A wild, neo-pulp ride through a world like Star Wars crossed with the underground ZAP! Comix, the ending will punch you in the gut and remind you why we flee to fictional worlds.

I was hooked on this locked room mystery from the opening premise: six newly minted clones awake on a generation ship and must solve their own murders.

The rest of the story did not disappoint, taking me on a crash course through the history, ethics, and sociological implications of cloning, a technology that in this future society has made many people functionally immortal.

I love a satisfying mystery, especially one with strong sci-fi underpinnings, so this really hit the spot for me.

I can still quote the opening of this novel verbatim: "It was around the hub of the evening on the planet of Porlumma that Captain Pausert, commercial traveler from the republic of Nikkeldepain, met the first of the witches of Karres. It was just plain fate, so far as he could see." Thus opens the most delightful romp in all of science fiction. When Pausert rescues three enslaved young girls, he sets in motion a comedy of errors, conspiracy, piracy, and intrigue that expands to involve the entire galaxy. Just who are these mysterious witches of Karres, and how can Captain Pausert return them safely to their home when everyone who's anyone is out to get them...and him?

Science fiction for those who don’t want to be bogged down by constant warfare. Drama still exists, but it is of a softer, quieter nature. It doesn’t grab you by the lapels and shove your face into a reactor, but this series will still entertain you with its gentility and warmth. The characters grow over time and become more interesting. The world-building is also quite something, well thought-through and easy to get lost in. The prose is excellent, flowing easily. There are touches of dry humor that had me smiling. One of my very favorite science fiction series.

This book takes us into a space colony populated solely by females who live in a symbiotic relationship with their organic starship. The ship is their shelter and protector, and in return, the women birth tools and components that the ship needs to function.

I love the gory spectacle of these bloody, mechanical births but also how they allow Hurley to explore ideas about community, duty, and belonging. The book is part of a wider sensibility that can be found throughout Hurley’s work, but for my money, this is the one where her imaginative powers are most successfully harnessed. 

Two fantastic cities are even better than one.

At the center of the story is Spearpoint, the tallest skyscraping megabuilding that you could imagine. It is so enormous that it is divided into segments from bottom to top with different levels of technology (Horsetown and Steamville at the bottom, cybertowns, and then the fantastic Celestial Levels at the top). But wait, there’s more.

Roaming the rest of the planet is the Swarm, hundreds of giant aircraft that function together as the neighborhoods of a “distributed city” much like the fleet in Battlestar Galactica. The very different cities do not play well together, and you get to choose which one you’d rather live in. I like flying, myself.

This is less a romance novel and more a high fantasy novel with romantic elements, but the romance subplot is exceedingly strong.

(I can highly recommend a mental fan-casting of either Arhys or Ilvin as Pedro Pascal, because he’d absolutely knock one of those roles out of the park if this was ever made into a miniseries).

Ista is over 40, a queen, a new grandmother, a recovered madwoman, and…wait for it…a living saint. Seeking to get away from the suffocating (yet loving) arms of her family, she goes on a pilgrimage (Road Trip!) with a group of younger people and ends up getting into multiple adventures and a more than near miss with outright war. It’s an absolute romp and one of my all-time favorites.
