Book cover of The Quantum Curators and the Faberge Egg

A.C. Huntley Author Of The Galactic Zookeeper's Guide to Heists and Husbandry

From my list on humorous sci-fi books with female protagonists.

Why am I passionate about this?

When I was a child, the thing that plagued me most about my favorite genre, sci-fi, was that none of the protagonists were women! As a daughter to doctors and research scientists, it felt strange that the only female characters in sci-fi were these buxom, mystical healers or seamstresses who meekly repaired their crewmates’ uniforms. While that problem has been remedied over the last two decades of excellence in mainstream sci-fi with some truly unforgettable female heroines, they’re not as plentiful in the niche market of humorous sci-fi. I am thrilled to share this list of my favorite lighthearted, humorous sci-fi reads with female protagonists. 

A.C.'s book list on humorous sci-fi books with female protagonists

A.C. Huntley Why A.C. loves this book

I thoroughly enjoyed this fun read. It’s unfortunate that this book has been compared to The Chronicles of St. Mary’s by Jodi Taylor (which is another enjoyable read but quite different).

While they share a similar premise–the Quantum Curators travel to parallel universes to rescue artifacts that would have otherwise been destroyed–the writing in the Quantum Curators really shines on its own. The mystery aspect kept me glued to the book, and along the way, I learned quite a bit about Russian history and Fabergé eggs.

I found that I enjoyed the budding romance and the friendships in this book, but I was devastated by the betrayal that was revealed at the end.

What is this book about?

Anyone can track down a priceless artefact that’s been lost for hundreds of years. Finding one that’s been hidden on a parallel Earth… now that’sa neat trick.

When Neith Salah – a quantum curator charged with traveling to our parallel Earth to rescue precious artefacts – is ordered to save a priceless Fabergé Egg, she figures it’s just another job. The only problem: she’s not sure what the egg looks like. Or where it is. Or when it is.

Enter Julius Strathclyde, a mild-mannered Cambridge professor whose closest brush with death-defying treasure hunts is finding lost coins down the back…

A.C. Huntley Why A.C. loves this book

I enjoyed the pacing of this action-packed book.

Cuban-descended protagonist Eve Innocente is trying to rescue her kidnapped sister from a galactic crime syndicate known as the Fridge. What really carried me through the story were the whacky shenanigans along the way, including a cargo hold full of psychic cats. This book had such a fun feel!

What is this book about?

"Jam-packed with weird aliens, mysterious artifacts, and lovable characters... a tremendous good time and an impressive debut." -- Kirkus Reviews (starred)

A hilarious, offbeat debut space opera that skewers everything from pop culture to video games and features an irresistible foul-mouthed captain and her motley crew, strange life forms, exciting twists, and a galaxy full of fun and adventure.

Captain Eva Innocente and the crew of La Sirena Negra cruise the galaxy delivering small cargo for even smaller profits. When her sister Mari is kidnapped by The Fridge, a shadowy syndicate that holds people hostage in cryostasis, Eva must undergo…

A.C.'s book list on humorous sci-fi books with female protagonists

A.C. Huntley Why A.C. loves this book

It is so easy to slip into this fun romp of a novel.

Scharlette is a bit of a mess, like most modern women. She doesn’t have her life in order–in fact, what she does have is a boring job and love handles. When she bumps into a time agent named Tomothy, she insists on tagging along for what proves to be a fast-paced, crazy adventure.

For me, the tongue-in-cheek humor is the best part. I adore these novels and am always thrilled to recommend them to someone who’s uninitiated.

What is this book about?

Ever since Scharlette’s parents gave her a name no one can pronounce, she’s been stuck in a bit of a rut. She hates her job in airport security, making people take their belts off before they fly to exotic locations she can only dream about. She owns a small apartment with large repayments, drinks bargain bin red on a couch that swallows gym memberships, and misses her little sister – lost to an exploding sandwich press, ten years ago.

Scharlette fears she might live her whole life without doing anything or mattering to anyone. Still, it comes as quite a…


Book cover of Crisis in Silstrand

J.L. Stowers Author Of Vengeance Lost

From my list on space opera written by women.

Why am I passionate about this?

I’ve held a burgeoning interest in the stars since I was a young girl. Daydreams of adventure and exploration guided me to the genre. Once I found it, I consumed everything I could find, both on-screen and in the pages of books. There’s something to be said about the vulnerability of being in the vastness of space, oftentimes with strangers who grow to be family. I guess, in a way, it reminds me of that moment when we set out into the world, away from our families, to learn and explore more about our surroundings and the characters we meet along the way (only on a much grander scale).

I don’t typically read military sci-fi or hard science fiction, but these two incredible authors have pulled me in. This series is part of a bigger universe called Aeon 14 and all of it is a joy to read. The authors work together to weave a story full of well-developed characters, flawless character interactions, along with conflict and resolution.

Nicole has done something really great with this series. She’s created memorable, detailed characters to build a cast you really care about. I really love seeing how other authors have humans interact with aliens and vice versa. This series was a great blend of everything you need for an epic adventure.

What is this book about?

1900 pages of space opera adventure for fans of Firefly, Killjoys, and the Mandalorian... Holly Drake just got out of prison... but that doesn't mean she’s free.

The City of Jade Spires is no paradise, though everything about it says otherwise: the glimmering jade towers, the glow of a gas giant, and the 6 Moons balanced between four supposedly equal races.

Serving an unfair sentence like Holly’s clears up such a gross misconception pretty quick. When she walks free due to the intervention of a mysterious source, she soon realizes they want her to do something: Steal a priceless jewel…

Amy is amazing at writing characters you really care about. Her fans have dubbed her the Queen of Space Opera and they’re not wrong. On top of her characters, she does a great job with suspense and plot twists that make it hard to stop reading.

Book cover of The Eyre Affair

Verlin Darrow Author Of Kinney's Quarry

From my list on books with humor and suspense.

Why am I passionate about this?

I grew up in a family of readers who valued humor above all else. I’ve always sought out novels that weren’t full of themselves or too serious. For example, I don’t actually like literature for the most part (sacrilege?) As a result, I’ve veered toward upmarket genre books that amuse me. My list reflects what I discovered as I explored this realm. It also led me to write mysteries and thrillers that are infused with my version of humor, which I must admit will never match the authors on my list. These guys are amazing.

Verlin Darrow Why Verlin loves this book

Fforde takes literary characters and brings them to life in a mystery format. Inside jokes about them and well-constructed absurd situations kept me amused. I admire the creativity and imagination a book like this requires. The plot is also ingenious, with unexpected twists and turns.

I’d say I never read a book like it, but I’ve read others by him, and he continues to create fun novels with literary and fairy tale characters. I recommend all of them.

Meet Thursday Next, literary detective without equal, fear or boyfriend

Jasper Fforde's beloved New York Times bestselling novel introduces literary detective Thursday Next and her alternate reality of literature-obsessed England-from the author of The Constant Rabbit

Fans of Douglas Adams and P. G. Wodehouse will love visiting Jasper Fforde's Great Britain, circa 1985, when time travel is routine, cloning is a reality (dodos are the resurrected pet of choice), and literature is taken very, very seriously: it's a bibliophile's dream. England is a virtual police state where an aunt can get lost (literally) in a Wordsworth poem and forging Byronic…


Book cover of Nexus Talks to Aliens

Julia Huni Author Of The Vacuum of Space

From my list on Science Fiction books to make you smile.

Why am I passionate about this?

My tagline is “sci-fi with heart and humor,” and that’s the core of who I am. Making others smile is my reason for being—whether that’s through the books I write, the silly things I say, or the crazy things I do. I’ve written twenty-eight books so far, and the purpose of every one of them is to make you giggle. I’ve written funny sci-fi, cheerful space opera, and a series of terrestrial romantic comedies set in a kitschy, over-the-top small town. 

Julia's book list on Science Fiction books to make you smile

Julia Huni Why Julia loves this book

This book isn’t objectively funny, but it left me with a smile on my face. It has a well-written, believable, neurodiverse character who grabbed my heart. I have a child on the autistic spectrum, and Booth captured the essence of autism without slipping into the depressing parts.

Nexus’s confusion over things “normal” people do, for example, tickled my funny bone but didn’t make me laugh. The characters who help him on his journey aren’t sappy do-gooders but people who genuinely like him and want to help. The overall tone of the book made me believe the world could be a better place.

He sets off to explore human space.

But to leave home, he must first repay a debt of honor, and smuggle a highly illegal sentient robot off-planet. Memory murky, the poor robot got stranded on Earth before Nexus was born.

Nexus is delighted when the alien ambassador boards his space train to Luna. Most…

AM Scott Author Of Lift Off

Why am I passionate about this?

I’ve published eleven classic-style space opera novels, a novella, and many short stories. Before becoming a writer, I spent twenty years in US Air Force in space operations; even though my books are light on science, I really was a rocket scientist!
