Book cover of Do Androids Dream of Electric Sheep?

Dennis Danvers Author Of The Soothsayer & the Changeling

From my list on transform how we see ourselves in the world.

Why am I passionate about this?

My first true religion was being a boy alone in the woods and feeling a deep connection to nature in all its aspects. I felt a connection with all life and knew myself to be an animal—and gloried in it. Since then, I've learned how vigorously humans fight our animal nature, estranging us from ourselves and the planet. Each of these books invites us to get over ourselves and connect with all life on Earth.

Dennis Danvers Why Dennis loves this book

I knew the film Blade Runner before I read this, the novel upon which it's based, but I was not prepared for the richer complexities of the novel.

My favorite parts of the novel, a bizarre new religion and the extinction of all but human and animal life, barely make it into the film. Even the androids, built to be slaves, are much more nuanced and complex than in the film. I loved the conclusion of the book, which affirms the beauty of life, both natural and mechanical.

Then Rick got his chance: the assignment to kill six Nexus-6 targets, for a huge reward. But in Deckard's world things were…

Book cover of A Memory Called Empire

Colin Brush Author Of Exo

From my list on science fiction murder mysteries.

Why am I passionate about this?

I think there are two great mysteries in our lives: the mystery of the world and the mystery of how we live in it. The branches of literature that explore these conundrums magnificently are science fiction for the world and murder mysteries for how we live. So, it is no wonder that the subgenre that most excites me has to be the science fiction murder mystery, in which, as a reader, I get to explore a strange new world and find out how people live (and die!) in it. This is why I read and, it turns out, what I write.

Colin's book list on science fiction murder mysteries

Colin Brush Why Colin loves this book

I love the hooky concept at this book’s heart: Mahit Dzmare is the new Lsel ambassador sent to the heart of the enormous Teixcalaanli galactic empire to maintain her tiny space station’s independence; but on arrival, she discovers her predecessor was murdered.

Now, she must not only act the diplomat, but she must also solve the murder without offending the very empire that at any moment could swallow her people whole.

The intricate-but-lightly-done world-building further helps bring this book to stunning life as Mahit walks a wobbly tightrope between asking difficult questions and preventing her very dangerous hosts from taking offence even as the politics take a dark turn, which threatens her life and everything she holds dear.

In a war of lies she seeks the truth . . .

Ambassador Mahit Dzmare travels to the Teixcalaanli Empire's interstellar capital, eager to take up her new post. Yet when she arrives, she discovers her predecessor was murdered. But no one will admit his death wasn't accidental - and she might be next.

Now Mahit must navigate the capital's enticing yet deadly halls of power, to discover dangerous truths. And while she hunts for the…


Book cover of Leviathan Wakes

Matt Shindell Author Of For the Love of Mars: A Human History of the Red Planet

From my list on human connection to space.

Why am I passionate about this?

One of the reasons I love my job as a Space History Curator at the Smithsonian’s National Air and Space Museum is that I am fascinated to learn how people think about space, the cosmos, and their human connection with the universe. I am always eager to get beyond questions of what we know and how we know it and ask: Why do we ask the questions we ask in the first place? The books I’ve listed here all explore our relationship with space and how we engage personally or collectively with space exploration.

Matt's book list on human connection to space

Matt Shindell Why Matt loves this book

This science fiction novel, written by Daniel Abraham and Ty Franck under the pen name James S. A. Corey, was the beginning of the Expanse series (now totaling 9 novels and additional stories). It is one of the best space science fiction novels of the 21st century and became the basis for one of my favorite TV/streaming series, The Expanse.

The books dive deep into the political, social, and cultural complexities of sending humans to live on the Moon, Mars, and the asteroid belt, and it’s a nuanced reflection of our current ideas and ambitions when it comes to spaceflight. I am particularly drawn to the depiction of humans who, after multiple generations off Earth, consider their primary identity to be Martian.

Book cover of The Hitchhiker's Guide to the Galaxy

L.N. Hunter Author Of The Feather and the Lamp

From my list on humorous fantasy and science fiction.

Why am I passionate about this?

Growing up at a time when both Monty Python and ‘alternative comedians’ like Ben Elton were on the telly, I couldn’t help but absorb British humor, and coupling that with a love of science fiction and fantasy (Asimov, Heinlein, Moorcock, etc.), I was ripe for an introduction to Douglas Adams and Terry Pratchett… And the rest is history. The world is too serious a place, and I find comedy of all kinds, but especially SFF, a welcome escape. My own writing has been inspired by all the books on this list, and while I work in a range of genres, almost everything includes at least some snarky humor.

L.N.'s book list on humorous fantasy and science fiction

L.N. Hunter Why L.N. loves this book

I first encountered Douglas Adams when I caught The Hitchhiker’s Guide on late-night radio, and I was hooked. The novel is slightly different, with Adams giving a bit more consideration to plot and logic, but it has the same wonderful, rapid-fire dialogue style, which has seldom been replicated.

I absolutely love Arthur Dent’s ludicrous accidental odyssey, meeting characters like Zaphod Beeblebrox and the wonderfully named Slartibartfast. The Guide sits in the background, popping up to provide superbly funny explanations of the history of the universe, humanity’s obsession with money, and a lot more.

For me, the thing that sets this apart from a lot of SFF humor is its ‘Britishness’—there’s a distinct feel of the surreal comic legacy of, for example, Monty Python and The Goon Show.

Book cover of Lock In

Janice Hardy Author Of Understanding Show, Don't Tell: And Really Getting It

From my list on novels that show and don’t tell.

Why am I passionate about this?

I love 'Show, Don’t Tell' because it really brings a novel to life for the reader. It’s something so many writers struggle with, but it can turn a so-so novel into one readers can’t put down. Losing yourself in a story is the sign of great writing, and when a writer can show me what’s in their head and do it in a way that makes me forget I’m reading, well, that’s a book that keeps me turning the pages until it’s done. And that’s my favorite part of reading, writing, and teaching writing. 

Janice's book list on novels that show and don’t tell

Janice Hardy Why Janice loves this book

I loved how Scalzi put the reader inside the head of his narrator and showed you his world as he saw it. Scalzi uses very little description, but I never felt that I was missing out or that the setting was weak. It was the opposite, really. I got hints and off-hand comments from the narrator that were great hooks to keep me reading, and I kept learning about this world and these characters all the way til the end.

It wasn’t until my second read that I even realized Scalzi did something absolutely brilliant. The “locked in” people of this world use robot bodies in the real world, but also have an online digital world. Scalzi describes the digital world in more detail, showing that Chris sees it as more real than the “real world.”

A blazingly inventive near-future thriller from the best-selling, Hugo Award-winning John Scalzi.

Not too long from today, a new, highly contagious virus makes its way across the globe. Most who get sick experience nothing worse than flu, fever and headaches. But for the unlucky one percent - and nearly five million souls in the United States alone - the disease causes "Lock In": Victims fully awake and aware, but unable to move or respond to stimulus. The disease affects young, old, rich, poor, people of every color and creed. The world changes to meet the challenge.

Book cover of A Confederacy of Dunces

PS Conway Author Of Life Sucks

From my list on satire with a bite.

Why am I passionate about this?

As a great-great-great-great-grandchild of Irish immigrants, I come from a long, proud line of alcoholics, especially on my mother’s side. My childhood was a masterclass in chaos: family scream-fests, flung insults, and someone cracking a joke while dodging a punch. It was painful, yes, but also absurd and often hilarious. That’s where my dark wit comes from. Razor-sharp humor was how we made it out alive. It becomes a lens you’re trained to observe the world through since you were a wee lad. I’ve always been drawn to stories where grief and laughter sit at the same table, clinking pints. Satire and absurdity aren’t interests for me. They’re muscle memory.

PS's book list on satire with a bite

PS Conway Why PS loves this book

I didn’t know whether to laugh or stage an intervention. This book introduced me to Ignatius J. Reilly, a character so insufferable and absurdly grandiose that I kept turning pages just to see how much worse he could get. I was horrified and hypnotized. I couldn’t look away.

What I love about this book is that it doesn’t ask you to like anyone. It asks you to witness the glorious wreckage of human delusion. It is chaotic, bloated, brilliant, and somehow still moving. Toole gave me a character I wanted to strangle, and a novel I wanted to reread. That kind of friction is rare, and I live for it.

Sara Davis Author Of The Scapegoat

From my list on detective novels that keep you page turning.

Why am I passionate about this?

I love reading mysteries, ever since I started back in junior high with Hercule Poirot, I have loved an atmospheric murder and ensuing investigation. As I’ve gotten older and started writing my own books, though, I’ve gotten pickier about what kinds of detective novels I can stick with—I now require that they also be excellent on the sentence level, which isn’t always easy to find. I also find that I gravitate towards books that have pockets of dry humor from time to time and a unique investigator.

Sara's book list on detective novels that keep you page turning

Sara Davis Why Sara loves this book

I am in awe of this book! I think it’s close to perfect, if not perfect. The detective here is Meyer Landsman, who “only has two moods: working and dead.” The novel is set in an alternate history that imagines Sitka, Alaska as a sprawling, Yiddish-speaking metropolis where all the Jews have fled after World War II.

The dead body is a mysterious young drug addict with connections to Sitka’s seedy underbelly. The story is a page-turner, but the sentences are truly incredible. It’s also very funny. I keep returning to this book year after year and every time it blows me away.

Book cover of Tea From An Empty Cup

Aaron Conners Author Of Tex Murphy and the Tesla Effect

From my list on combining science fiction and detective stories.

Why am I passionate about this?

I grew up reading the Hardy Boys, then Sherlock Holmes, then Hammett and Chandler. I’ve always been fascinated by mysteries and the process of solving them. This led me to create my own interactive murder mysteries, then a career designing and writing videogames. Two of the games, featuring a 1940’s-style P.I. living in the post-apocalyptic 2040s, won “Adventure Game of the Year” awards, and spawned a series of four (so far) novels. The stories, which combine light sci-fi with detective noir and a lot of humor, have been influenced by many different movies, tv shows, and books, including the five in this list. I hope you enjoy them!

Aaron's book list on combining science fiction and detective stories

Aaron Conners Why Aaron loves this book

Cyberpunk Noir isn’t everyone’s cup of tea (sorry), and this story is dark and downbeat, with two female protagonists who aren’t especially sympathetic, so readers tend to love this book or hate it. For me, the kinetic writing style, crackling dialogue, and richly-detailed descriptions of cyberspace—as well as the fresh take on the “locked-room murder” (a virtual reality parlor in this case)—makes it a highly-recommended read.

Through science fiction, especially in the books on this list, I seek out visions of better societies and ideas that could help shape a more hopeful world.

Larry's book list on explore strange worlds and new societies

Larry Haley Why Larry loves this book

I found this book to be a masterful blend of murder mystery and science fiction, taking us on a journey through a future world where robots are beginning to take over jobs. The ethical and social questions raised by the integration of robots into everyday life are more relevant today than they were when the book was first published in 1953.

I liked Asimov's insights into the effects of robotics, offering a reflection into our own world as the AI revolution unfolds. Asimov's writing style is engaging, balancing technical detail with compelling storytelling.

I enjoyed this book immensely, not just for its intriguing plot but also for its thought-provoking exploration of a future that in many ways feels increasingly plausible.

Colin's book list on science fiction murder mysteries

Colin Brush Why Colin loves this book

In my view, a great murder mystery should have a lot of possibilities, and science fiction just adds deeper layers of intrigue, and this is what The City and The City has in spades – literal layers and intrigue.

Here, two cities exist in the same place, yet the citizens of each one must ignore the citizens of the other. It is a crime to notice the citizens of the other city. When a murder occurs and our detective investigates, he only has jurisdiction in one city.

But what really blew my mind about this book was that, though it is science fiction, there is no physical or scientific reason that the cities are separate and occupy the same place. The division is only in the minds of the inhabitants!
