Book cover of Gideon the Ninth

Claire Barner Author Of Moonrising

From my list on sci-fi romance that will make you think.

Why am I passionate about this?

I’ve been obsessed with sci-fi romance since I was a kid watching the Klingon wedding of Worf and Jadzia Dax in Star Trek: Deep Space Nine. I love the idea of mashing these two distinct genres together. While sci-fi and romance both explore the human condition, sci-fi goes wide while romance is intimate. I think this makes the crossover of these two genres work especially well. My foremost inspiration for sci-fi romance is Lois McMaster Bujold, who offers a masterclass in how to deftly weave compelling romance into a sci-fi setting without sacrificing any action or political intrigue.

Claire's book list on sci-fi romance that will make you think

Claire Barner Why Claire loves this book

This book is unhinged in the best way. I love Gideon’s unique voice. Around her is a deadly-serious necromancer murder mystery with interplanetary stakes, and she cares more about cracking dirty jokes and finally eating some warm food. Her relationship with her arch-nemesis/only friend Harrow leaps off the page.

I love the scene where they get into a pool so Harrow can finally confess to Gideon her darkest secret—so hot and so disturbing all at the same time. While this book isn’t technically a romance and the genre feels more like a horror fantasy set in space, I couldn’t resist putting it on the list. As Gideon says to Harrow, “One flesh, one end, bitch.”

Book cover of The Book of Jhereg

Andy Peloquin Author Of Assassin

From my list on dark assassins and bloody action.

Why am I passionate about this?

I’ve always loved the darker side of fantasy. While heroes, knights, and handsome kings can occasionally be enjoyable, I want to know the other characters who have suffered, hurt, lost, grieved, and been hardened by grim circumstances and cruel fate. Those characters demonstrate the resilience of human nature and how goodness truly can exist even in the harshest environment. I love using this darkness in my own novels to show that even the tiniest spark can shine immensely bright—a true testament to the indefatigability of our spirits.  

Andy's book list on dark assassins and bloody action

Andy Peloquin Why Andy loves this book

I love the cunning, wit, and charm of the one-and-only Vlad Taltos. Though he’s an assassin, he’s never cruel or wicked; he merely does what he needs to appease the “mafia-feeling” organization he works for. He’s almost more a swashbuckling rogue than a killer.

In his interactions with his familiar, Loiosh, you see his more nuanced side, the morality beneath the magic and swordplay. And few fantasy worlds I’ve ever visited have been as rich and colorful as those created in the Vlad Taltos series.

From his rookie days to his selfless feats of heroism, the dauntless Vlad will hold readers spellbound—and The Book of Jhereg will take its place among the classic compilations…


Book cover of All Systems Red

Arthur Geis Author Of The Rocket Scientist

From my list on smart sci-fi for thinking readers.

Why am I passionate about this?

I grew up when the space race was starting, and I became fascinated by all things regarding the planets, rockets, and the cosmos. For several years, I lived in the Houston area and spent hours and hours at the Johnson Space Center, where the history and future of space exploration are on display. The books on my list represent a major theme in my writing, which is futuristic in concept and asks the question: what we would do if our planet became uninhabitable. The answer provides the canvas to explore the advantages of technology, but most importantly, the determination of the human spirit.

Arthur's book list on smart sci-fi for thinking readers

Arthur Geis Why Arthur loves this book

I love books that are clever, imaginative, and portray a particular person or character as the main theme. This book does it for me.

The character is a murderer robot, but I came to like him and his weird but insightful perspective. I could see his world through his eyes. I felt sorry for him by the end of the book and was rooting for him. That was great.

I always like a bit of technology thrown in, but not have it be the main story or too complicated that it gets in the way of the characters. The writing was especially good, and I found myself turning page after page, engrossed in the story.

Book cover of The City in the Middle of the Night

tammy lynne stoner Author Of Sugar Land

From my list on queer stories someone should bring to the screen.

Why am I passionate about this?

I started in publishing at the Advocate magazine, twenty years ago in its heyday, then moved to Alyson Books, who first published Emma Donoghue among many others, offering a place for queer writers showcasing queer stories to find their audience. Afterwards, I became involved with Gertrude literary journal, a beloved, 25-year-old non-profit, LGBTQA journal that has now evolved to The Gertrude Conference. All the while, I read, wrote, and supported queer stories, like these gems!

tammy's book list on queer stories someone should bring to the screen

tammy lynne stoner Why tammy loves this book

On the planet of January, one side is in permanent daylight and the other side is permanent night, with people managing to live on a strip of moderate light between the two extremes.

Sophie, a shy teenager, breaks the rules and is sent to the dark side to die, only she survives.  While she is in the dark, she meets telepathic creatures who, despite their terrifying visage, are kind-hearted—a shock to someone raised in a community who believes the creatures (and others) are awful because of the way they look.

Together with her best friend, Bianca, they decide to save the human race, against all dark odds, including secret outlaws. 

This TV series would showcase all the strange glory of Anders, along with the emotional depth that will have us rooting for our young heroines who literally go between the darkness and the light. Hey, J.J. Abrams, you listenin’?

What is this book about?

"If you control our sleep, then you can own our dreams... And from there, it's easy to control our entire lives."

From the brilliant mind of Charlie Jane Anders ("A master absurdist"-New York Times; "Virtuoso"-NPR) comes a new novel of Kafkaesque futurism. Set on a planet that has fully definitive, never-changing zones of day and night, with ensuing extreme climates of endless, frigid darkness and blinding, relentless light, humankind has somehow continued apace-though the perils outside the built cities are rife with danger as much as the streets below.

But in a world where time means only what the ruling…


Book cover of How to Invent Everything: A Survival Guide for the Stranded Time Traveler

R. E. Stearns Author Of Barbary Station

From my list on looking at the familiar differently.

Why am I passionate about this?

I’ve always read speculative fiction for its new perspectives on reality. Now that I write it too, I appreciate the fabulous minds that create these unique views of our universe even more. Experience in higher education and instructional design led me to appreciate organization that flows at the speed and direction of thought. I adore a well-turned phrase and a well-built world, and I hope this list leads you to a new experience of that same joy.

R. E.'s book list on looking at the familiar differently

R. E. Stearns Why R. E. loves this book

A lot of speculative fiction involves “basic” technologies like animal domestication, farming, and written language. This well-organized, thoroughly sourced non-fiction book will tell you just how difficult developing all that stuff was on our planet, let alone in whatever fictional universes you may find these technologies in! I will never again take charcoal, or the concept of zero, for granted.

Aside from the book’s valuable content, its language is simple. The author integrates the facts into the fiction that our time machine has broken down, stranding us in a previous era where we are a long, arduous journey away from ever eating microwaved ramen again. North also points out, at every opportunity, all the ridiculousness and hilarity involved in invention, civilization, and attempting to do everything by ourselves. Please, read the footnotes in this one.

R. E.'s book list on looking at the familiar differently

R. E. Stearns Why R. E. loves this book

Many readers fear math, and this action-packed adventure may give you new reasons to fear it. The protagonist’s superpower is super-fast mental calculation that lets her dodge bullets and kick incredible quantities of butt in a fight. Even more devious minds are opposing her. If you’ve ever wondered what use your high school physics and calculus classes were, this novel offers some explanation, although you can appreciate the story without them. This is, and I cannot stress this enough, a fun and exciting tale that treats math like magic and totally gets away with doing so.

R. E.'s book list on looking at the familiar differently

R. E. Stearns Why R. E. loves this book

If you, like me, have to consciously choose to read more poetry, this is a fascinating book to add to your collection. The poems’ subjects range from pop culture to body horror to the titular implications of algorithms and AI, and every one of them is a well-structured look at an apocalypse, large or small. Chances are excellent that you will encounter an English word you can’t readily define. Many of the poems are illustrated with haunting and/or humorous line art which even the ebook format renders well. Everything ends, but not every description of those endings are as beautiful as the ones in this book.

Why should I read it?

1 author picked Dawn of the Algorithm as one of their favorite books, and they share why you should read it.

What is this book about?

Dawn of the Algorithm, Yann Rousselot’s debut collection of poetry, is a bestiary of octosharks and dinosaurs, zombies and pathogens, mecha robots and common mortals.

These monsters were raised on a diet of TV tropes, movie clichés, book snippets, and video game storylines. Some have beating hearts, others interlocking mechanical parts. They are forces of human nature, genetically engineered with a single purpose: to herald the apocalypse.

Building on user-friendly motif and imagery, Rousselot draws acute, playful but painful conclusions about twenty-first century Earth. He paints a darkly comical portrait of humankind, a species plagued by heartbreak and alienation, yet…


Book cover of On the Edge of Gone

Riley Odell Author Of Divergent Realms: Science Fiction and Fantasy Stories About Neurodivergence

From my list on about neurodivergent characters.

Why am I passionate about this?

I’m an autistic writer with a passion for neurodiversity representation in fiction. As a child, I struggled to get into reading because I couldn’t see myself in any of the characters. That changed when I discovered Calvin and Hobbes, a comic strip about a precocious boy with a big imagination who struggles with making friends and is always getting in trouble for his poor self-control. Finally, I thought—a character just like me! For people who are neurodivergent, discovering fictional characters who resemble themselves can be a powerful experience. That’s why I think neurodiversity representation in fiction is incredibly important. 

Riley's book list on about neurodivergent characters

Riley Odell Why Riley loves this book

Corinne Duyvis is autistic, and so is the narrator for this book, Denise. Unsurprisingly, given she shares the disorder, Duyvis has absolutely nailed this aspect of the character. As an autistic person myself, Denise feels relatable to me in a way that few fictional protagonists do. 

While other characters in the book struggle to understand her, her habits and mannerisms frequently make me say, “Hey! That’s like me!” Nothing beats having that experience with a character, and the book’s story, which sees Denise use her unique talents to attempt to secure a place for her family on a generation ship fleeing from catastrophe on Earth, is well-crafted and gripping throughout.

January 29, 2035. That's the day the comet is scheduled to hit-the big one. Denise and her mother and sister, Iris, have been assigned to a temporary shelter outside their hometown of Amsterdam to wait out the blast, but Iris is nowhere to be found, and at the rate Denise's drug-addicted mother is going, they'll never reach the shelter in time. A last-minute meeting leads them to something better than a temporary shelter-a generation ship, scheduled to leave Earth behind to colonize new worlds after the comet hits.…


Book cover of Nophek Gloss

Rohan Oduill Author Of Cold Rising

From my list on science fiction books with working class heroes.

Why am I passionate about this?

Having spent thirty years working as a chef, I was always going to have working-class heroes in my stories. When someone said this is uncommon in science fiction, I didn’t believe them. But then I couldn’t think of any. I started searching through my bookshelves, and still, I couldn’t find enough to fill this list. I asked on socials and eventually found five books. 

It would seem natural that in a science fiction world of adventure and exploration, the professionals would be at the forefront. But I am pretty sure that the toilet cleaners on the Death Star would still have a story or two to tell.

Rohan's book list on science fiction books with working class heroes

Rohan Oduill Why Rohan loves this book

It became obvious to me early in this book that Nophek Gloss was written by someone who works with their hands. Not only in how the action was choreographed but also in how the world was described.

This brings a real world feel to the writing as we join Caiden helping his father with the menial tasks that keep a farming community running. Soon after, his whole world is destroyed. But as Caiden escapes and throws in with a ragtag bunch of aliens and a ship with a conscience, we can appreciate his point of view as someone who has seen so little of the universe but is suddenly exposed to multitudes of new and unusual things as he adventures into the unknown.

This book is for sci-fi fans who enjoy great worldbuilding, interesting aliens, and action throughout.

Book cover of Ninefox Gambit

Robyn Bennis Author Of The Guns Above

From my list on great twist on spaceships.

Why am I passionate about this?

I have wanted to live on a spaceship since I was eight years old, watching reruns of Star Trek on the local UHF channel. At eight, I couldn’t have told you why. The Enterprise, by the twin miracles of sci-fi tech and TV budget, has the same gravity, air, and people (mostly) we have right here on Earth. Later, I came to understand the appeal: on the Enterprise, the only true enemy is space itself, unfeeling and impersonal in its hostility. The only hate in space is what we bring with us, and the silent, empty gulfs between worlds remind us that we can choose to leave it behind. 

Robyn's book list on great twist on spaceships

Robyn Bennis Why Robyn loves this book

Reading the first couple of chapters of this book is like being thrown into the deep end of a pool and asked not just to swim but to do some calculus homework while you’re at it. The setting just doesn’t seem to make any sense, physically or morally. But I kept treading water until this book had a grip on me that wouldn’t let go. By the time the concept of “Calendrical Heresy” came up, I couldn’t put it down.

In this book, spaceships (and their horrifying, inhumane weapons) run on forces that depend on the calendar. Change the calendar and you change the rules of reality itself. This unique bit of worldbuilding lays the foundations for a gritty, unwavering exploration of personal identity under the heels of oppression, and holy crap, is it a wild, profound journey.
