Sci-Fi has many amazing subgenres, ranging from dystopian to hard sci-fi to alien invasion, but my absolute favorite is space opera.
While definitions vary, most readers agree that space opera includes melodramatic tales of warfare, romance, adventure, and action, often in space (generally on the galactic level) and usually with the universe at stake.
If you’re ready to spend some time in the deep black of space, strap in and get ready to add some of these amazing space opera books to your TBR.
Explore The Galaxy With These Highly-Recommended Space Opera Books (And Series)
Firefly: Carnival by Una McCormack
Firefly Novel #6
Content Warnings (may contain spoilers):
Kidnapping, Violence, Trafficking, Death (Note: This list doesn't include all content warnings. Please do your own research before reading this book.)
Firefly is the perfect introduction to Western-style space opera books if I do say so myself. If, like me, you're a fan of the TV show, you’re probably still mourning its cancellation. If you’re not familiar with the show, it follows Captain Mal of the Serenity, who’s just trying to make ends meet in a post-war galaxy. The outer rim is a bit of the wild west, where Serenity and her crew can pick up jobs, but most come with risk and complications.
This book series is very much based on the TV show but introduces new adventures for Captain Mal and the crew of the Serenity. In Carnival, the crew finds themselves in a desert city known as the City of Sin. When the job goes bad, as luck would have it, the crew must get creative to resolve the situation and make sure everyone makes it out alive.
While many of the first books were written by James Lovegrove, the concept was created by Nancy Holder, and additional novels have been written by Tim Lebbon, M.K. England, Una McCormack, and Rosiee Thor. Each writer has a slightly different style, but overall keeps to the spirit of the series. Be sure to check out the other books in the Firefly series for more adventures with the crew and see if they can keep Serenity flying.
Some Desperate Glory by Emily Tesh
Spice Level: 🌶️ (Extra Mild)
Content Warnings (may contain spoilers):
Suicide, Violence, War, Homophobia, Rape, Sexual assault, Pregnancy, Abortion, Racism, Sexism, Ableism (Note: This list doesn't include all content warnings. Please do your own research before reading this book.)
Get ready to be uncomfortable while reading this popular queer dystopian coming-of-age space opera. After the Earth was brutally murdered, humanity’s last hope lives on Gaea Station and is preparing to do whatever it takes to get revenge.
17-year-old Kyr has spent her whole life training to do her part for the cause. A fierce warrior, she’s privileged to call the Commander Uncle and will stop at nothing to ensure humanity gets its revenge against the malicious majo (aliens). That is, until her twin brother goes missing and she finds herself on a path that makes her question everything she’s ever known.
I love a good dystopian story set in space. While the female protagonist was rather infuriating at the beginning of this book, I loved the growth and depth of her character as she navigated and processed her world, fully unpacking what it means to seek revenge. This is a dark, heavy standalone novel with major content warnings, so be sure to check them out before diving in.
Winter’s Orbit by Everina Maxwell
The Resolution Universe #1
Spice Level: 🌶️ (Extra Mild)
Content Warnings (may contain spoilers):
Domestic abuse, Emotional abuse, Toxic relationship, Physical abuse, Torture, Violence, War, Murder, Death, Hospital/Medical facility (Note: This list doesn't include all content warnings. Please do your own research before reading this book.)
If you’re looking for a romantic space opera novel with an extra dash of political intrigue, arranged marriage, and a murder mystery, be sure to check out Winter’s Orbit.
When Prince Kiem is forced to marry a widower (and murder suspect) Count Jainan, neither of them is too pleased about the arrangement. Their marriage will, of course, be great for relations between the Empire and the vassal planet Thea, provided Jainan proves innocent of his former husband’s death.
This was such a delightful space opera, featuring two main characters stuck in a situation neither wants to be in. The Resolution Universe is a very interesting place to be, and I found it especially intriguing that each planet in this galaxy has its own unique way of showing gender.
With the two different POVs, we get a really clear picture of how two people can experience and think about things in very different ways. I really enjoyed how the story came together while also discussing the concepts of duty/service and self-worth.
For more adventures in this world, check out the companion novel, Ocean’s Echo (2022).
Future's Edge by Gareth L. Powell
Spice Level: 🌶️ (Extra Mild)
Content Warnings (may contain spoilers):
Death, Violence, Murder, Genocide, Body horror, Kidnapping (Note: This list doesn't include all content warnings. Please do your own research before reading this book.)
In this action-packed space opera, humanity is fighting for its life against an unbeatable foe. The fate of the world seems to be left in the hands of Ursula, an archaeologist infected with an alien parasite, Jack, the soldier who saved her from humanity’s destruction, and his ship, Crisis Actor (but you can call her Cris). Together, they have a plan, but it involves a bit of space piracy and luck. What could possibly go wrong?
The story is told primarily from the main character, Ursula’s, point of view, with a few chapters (logs) from Crisis Actor’s point of view.
This was a fast-paced story full of complicated relationships, interesting characters, and tough challenges. There were a lot of things I really enjoyed about this story, including ships that talk, different species, crews working together, a bit of a heist, and underdogs doing their best to save the world when all hope is lost. I really love the crew aboard the Crisis Actor and enjoyed being along for the ride.
To Sleep in a Sea of Stars (2020) by Christopher Paolini
Fractalverse #1
Spice Level: 🌶️ (Extra Mild)
Content Warnings (may contain spoilers):
Violence, Gore, Body horror, Sexual content, War, Death, Alcohol, Confinement, Genocide (Note: This list doesn't include all content warnings. Please do your own research before reading this book.)
Come aboard the Wallfish and strap in for an eventful journey through the Fractalverse. Kira, a xenobiologist, studies life beyond Earth, but she never thought she would become a test subject herself.
After the discovery of an alien relic, her life takes an unexpected turn, as does the future of the galaxy. This popular military sci-fi space opera features first contact, a long space journey, alien artifacts, intergalactic war, and so much more.
After journeying through the Fractalverse with Kira, I felt like I really got to know her and her found family, and I look forward to more stories in this world.
Pushing almost 900 pages, this medium-paced story is perfect for those ready to go on a long space journey and really explore what it means to be human.
Be sure to check out the prequel, Fractal Noise (2023), and keep an eye out for future releases in the Fractalverse.
Station Eternity by Mur Lafferty
The Midsolar Murders #1
Spice Level: 🌶️ (Extra Mild)
Content Warnings (may contain spoilers):
Murder, Blood, Injury/Injury detail, Violence, Drug use, Death, Death of a parent, Cancer, Suicide (Note: This list doesn't include all content warnings. Please do your own research before reading this book.)
It’s not that Mallory Viridian can’t stand being around other humans; it’s just that whenever she is around too many, someone ends up murdered. No, she’s not a serial killer... Yes, she has her own SBI agent... Yes, she can probably solve the crime if you let her take a good look around... No, she doesn’t have many friends.
In a desperate attempt to never see another murder victim, Mallory takes the opportunity to move to Station Eternity, which boasts a human population you can count on one hand. When it’s announced that a shuttle of humans is inbound to the station, Mallory will find out if her curse still applies in space.
The world in this novel is fascinating and full of sentient spaceships, an intriguing space station, mysterious connections, diverse alien species, and murder mysteries. Mallory and her friends aboard Station Eternity have a great dynamic, and I loved getting to know them and learning more about this world as I read the series.
The stories, or dare I say murders, continue with Chaos Terminal (2023) and Infinite Archive (2025).
Ocean’s Godori by Elaine U. Cho
The Alliance #1
Spice Level: 🌶️ (Extra Mild)
Content Warnings (may contain spoilers):
Violence, Death, Fire/Fire injury, Gun violence, Grief, Murder, Racism, Classism (Note: This list doesn't include all content warnings. Please do your own research before reading this book.)
This action-packed space opera brings us to a cyberpunk world where Korea won the space race and political games are afoot. Ocean Yoon, a mysteriously disgraced pilot, has never felt Korean enough despite her heritage. A bit rough around the edges, Ocean lost her status after the mysterious events aboard the Hadouken and is now slumming it with a ragtag crew aboard the Ohneul.
When Ocean’s best friend, Teo, shows up needing help, her crew finds themselves caught up in a high-stakes mission that they’ll need extra help to resolve.
This world is home to some very interesting and distant characters and cultures. The camaraderie and banter among the diverse cast of characters in this book were really well done, and I enjoyed getting to know them as they dealt with raiders, hijinks, betrayal, questionable choices, and twists.
Ocean’s Godori is the first book in a duology, followed by Teo’s Durumi (2025).
Space Opera by Catherynne M. Valente
Space Opera #1
Spice Level: 🌶️ (Extra Mild)
Content Warnings (may contain spoilers):
Xenophobia, Genocide, Death, Sexual content, Car accident, Deportation, Drug use, Racism, Vomit (Note: This list doesn't include all content warnings. Please do your own research before reading this book.)
What would you say if the fate of humanity relied upon a random musician from the UK? In this galaxy, after the Sentience Wars tore everything apart, an intergalactic song competition was introduced to replace battlegrounds. The winner doesn’t really get a prize, but the loser loses the literal game of life.
The story is told through three distinct storylines: current events, the backstories of Decibel Jones and the Absolute Zeros, and the history of the galaxy and overall competition. At this cycle’s Metagalactic Grand Prix, humans compete for the first and possibly last time.
Space Opera was a deeply satiric and entertaining read, full of twists on song titles, clever commentary, and many pop culture references. The different species described in this world were fascinating, and the history of the life-or-death intergalactic song competition was entertaining.
While this book can be read as a standalone, be sure to also check out Space Oddity (2024), which continues the story with a new challenge for humanity.
Whether you’re in the mood for a side of western, extra epicness, heists, aliens, politics, or murder mystery with your space opera, there’s a sci-fi book or series out there waiting to share its melodrama with you. Happy reading!
