Book cover of Seveneves

Johnny B. Truant Author Of Dead City

From my list on Sci-Fi real science that justifies unreal things.

Why am I passionate about this?

Before I was an author, I was a scientist pursuing a PhD in molecular genetics. When I left the lab and started writing, that scientist’s need for real-world sense stuck with me and became a theme in everything I write. The authors I like understand that “suspension of disbelief” is a limited resource, so they’d better only ask readers for it when it counts. Get the baseline facts and logic right, and I’ll believe and enjoy the fantastical stuff spun from it so much more. 

Johnny's book list on Sci-Fi real science that justifies unreal things

Johnny B. Truant Why did Johnny love this book?

I love it when a book shows me the real consequences of something I’d never considered, such as this book’s breakup of the moon. It creates true fear that hooks me into a story because once I see the truth, I find it hard not to believe it. 

Everything that follows feels exactly the way Earth scientists would really deal with an apocalyptic event…and the way humans would, too, as they jockey for superiority and power. (Psychology is a science, too!) Exciting events are always grounded in the consequences of physics and biology…including the book's name, which took most of the story to make sense!

Book cover of Empire of Silence

D.J. Butler Author Of Witchy Eye

From D.J.'s 3 favorite reads in 2023.

D.J.'s 3 favorite reads in 2023

D.J. Butler Why did D.J. love this book?

Empire of Silence kicks off an epic space fantasy in the style of Gene Wolfe or Frank Herbert.

If you think Dune started well but went off the rails, try Empire of Silence. If you think the Book of the New Sun needed more sword duels and ship to ship space combat, try Empire of Silence. If you think Star Wars was pretty good, but that maybe Darth Vader is the unappreciated hero… Empire of Silence is the book for you.

What is this book about?

Hadrian Marlowe, a man revered as a hero and despised as a murderer, chronicles his tale in the galaxy-spanning debut of the Sun Eater series, merging the best of space opera and epic fantasy.

It was not his war.

On the wrong planet, at the right time, for the best reasons, Hadrian Marlowe started down a path that could only end in fire. The galaxy remembers him as a hero: the man who burned every last alien Cielcin from the sky. They remember him as a monster: the devil who destroyed a sun, casually annihilating four billion human lives--even the…


Book cover of Communion

Matthew Bowman Author Of The Abduction of Betty and Barney Hill: Alien Encounters, Civil Rights, and the New Age in America

From my list on understanding the UFO phenomenon.

Why am I passionate about this?

I remember as a child reading all sorts of books about spooky things like UFOs. When, as an adult, a scholar of religion, and academic I decided I wanted to write something about how technology and science and the Cold War impacted how Americans believed things, and what they believed in outside the boundaries of traditional religion, I remembered those books. I began poking around in the world of UFO sightings, reading both believers and academics like me fascinated by how this particular network of stories and beliefs have gotten such a chokehold on American popular culture. And I’ve found the rabbit hole just keeps going.

Matthew Bowman Why did Matthew love this book?

Over the thirty-odd years since its publication, Strieber’s haunting story of his own encounters with strange creatures—perhaps from outer space, perhaps from another layer of reality, perhaps from his own mind—has become the most popular and profound first-person account of alien encounters in modern American culture. 

This is in part due to Strieber’s prose, both fevered and fiercely precise. He was a successful horror novelist before producing this book, and whether one believes he is simply continuing his trade here or not, his story is compelling, terrifying, philosophical, and deeply disorienting.

By Whitley Strieber,

Why should I read it?

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

What is this book about?

Communion is the iconic classic in which Whitley Strieber describes his 1985 close encounter experiences. This book, which fundamentally changed the way we understand close encounters and alien abductions, is presented here with a new introduction by the author.


The message of Communion, that something unknown is really happening to people but that we have not studied it enough to understand it, remains as timely now as it was in 1987 when the book was first published. And Whitley Strieber's riveting account of what he experienced, along with his relentless and expert pursuit of the reality behind the experience, is…


Book cover of Sailing Bright Eternity

Rich Larson Author Of Ymir

From my list on sci-fi to bend your brain and crush your soul.

Why am I passionate about this?

I’ve been writing professionally for an entire decade now, and for most of that time sci-fi has been my bread and butter. I love the genre’s varied aesthetics, and its tightrope of creativity and believability. The sci-fi books I love most of all are, for whatever reason, the ones that make me think deep, none-too-happy thoughts. Best is subjective, but these are five of my very favorites.

Rich's book list on sci-fi to bend your brain and crush your soul

Rich Larson Why did Rich love this book?

The first sci-fi I ever read, plucked from a dusty shelf on a mission compound in Niger. The physics explanations were beyond me, and honestly still are, but the astronomical imagery rewired my nine-year-old brain. This is a book (and series) that melds the rigor of hard SF with the scope and imagination of the best space opera, following the remnants of humanity as they flee inscrutable, implacable AI monstrosities. It makes the universe feel visceral and terrifyingly beautiful, and makes the reader feel like an ant.

What is this book about?

This new, special edition of the classic concluding volume of this defining series by the eminent physicist and Nebula Award-winning author contains a teaser chapter from Benford's, The Sunborn.
The final chapter of humanity's future has begun, and three men hold the key to survival. As the fierce, artificially intelligent mechs pursue their savage and unstoppable destruction of the human race, it soon becomes apparent that three men-three generations in a family of voyagers-are their targets. Toby Bishop, his father Kileen, and his longdead grandfather each carry a piece of the lethal secret that can destroy their relentless pursuers. There…


Book cover of The Wrong Stars

J. S. Fields Author Of Ardulum: First Don

From my list on space lesbians.

Why am I passionate about this?

In my day job I’m a professor in a hard science and, unsurprisingly, a lesbian. I love sapphic fiction, especially speculative sapphic fiction, but it can be hard to find as the books are seldom labeled as such. Because I write in this genre I’ve been able to ferret out a lot of them, and have made it a mini mission to read as many as possible. I’m particularly drawn to those that get science right (bad science to a science professor is like nails on a chalk board), and those that have at least a little bit of kissing.

J.'s book list on space lesbians

J. S. Fields Why did J. love this book?

Good space opera is built on time-honored tropes, and Pratt hits them all on the head. Space princess? Check. Ragtag crew? Check. Strange, otherworldly aliens and a dash of romance? Double check. The Wrong Stars is space opera at its finest, with a classic adventure between humans and aliens, good versus evil, and technological innovation that makes you stop and consider current trends. 

The romance line is sapphic, age gap, flirtatious and commanding. Callie is our commanding captain, cool and in charge. Elena has been in cryosleep on a generational ship that was attacked by violent aliens and has some trauma to work out. Who better to help than Callie? And of course the whole crew needs to go investigate these new aliens. The fate of the galaxy is at stake!

The shady crew of the White Raven run freight and salvage at the fringes of our solar system. They discover the wreck of a centuries-old exploration vessel floating light years away from its intended destination and revive its sole occupant, who wakes with news of First Alien Contact. When the crew break it to her that humanity has alien allies already, she reveals that these are very different extra-terrestrials... and the gifts they bestowed on her could kill all humanity, or take it out to the most distant stars.

Book cover of Last Man Standing

Douglas Phillips Author Of Quantum Space

From my list on hard science fiction published this century.

Why am I passionate about this?

As a scientist, I love hard science fiction, especially when the story makes me think about the true nature of reality or takes me on an adventure to places unknown. We’ve all read the classics from Clarke, Heinlein, Bear, or Asimov. But books written decades ago are becoming increasingly dated as society progresses into a new century. (Will people of the future really chain smoke? And why are all the characters men?) Never fear, modern hard sci-fi is alive and well. Here are five recent books that tell an intriguing, uplifting, or awe-inspiring story. Even better than the classics, it’s hard sci-fi for the 21st century!

Douglas' book list on hard science fiction published this century

Douglas Phillips Why did Douglas love this book?

I normally avoid dystopian, but this story doesn’t dwell in misery like so many apocalyptic stories do.

Last Man Standing is more like Andy Weir’s book, The Martian, because it’s about one man’s survival under extreme conditions. A scientist is stranded on a space station after an attack that has killed everyone else onboard. What happened, and why? He doesn’t know, but he’ll do anything to stay alive and find a way to get back to Earth despite a thousand obstacles in his path and little knowledge of spaceflight.

This story can be intense, but the character stays positive and has a lot of heart.

Book cover of On A Sunbeam

Deanna Grey Author Of Outdrawn

From my list on sapphic romance with characters finding their place.

Why am I passionate about this?

I’ve always loved writing that explores mental health and its effect on finding love. I love characters who are their worst enemies and conflicts stemming from internal battles. Depression and anxiety have been something I’ve struggled with since childhood. My mental health issues made looking to the future with hope feel impossible sometimes. When I picked up a romance book where an anxious character found a happily ever after, it gave me hope. Seeing characters who don’t have everything figured out and aren’t always confident in themselves find their happy endings is a light at the end of a tunnel—peace in the middle of a storm.

Deanna Grey Why did Deanna love this book?

This book follows the main characters and their journey through finding young love, dealing with loss, and becoming resilient to what life throws them. The art in this book is a wonderful blend of fantasy and science fiction.

I love how the story plops you into the world but doesn’t explain how everything works. Stories without info dumps make me feel like the author trusts their characters, and visuals can stand alone.

Book cover of Cold Welcome

Felicia Watson Author Of We Have Met the Enemy

From my list on sci-fi featuring awesome female leads.

Why am I passionate about this?

In school, science and reading were always my favorite subjects so is it any wonder that I grew up to be a scientist who writes? Before I entered my teens, I entered the realm of science fiction through the stories of Asimov, Bradbury, and Le Guin, and I never willingly left that realm. Back then, the one thing I hungered for but so rarely found was a compelling female character. Avid readers all want to find that character to identify with, don’t we? Fortunately, our sci-fi world is now populated with many great female MCs so I’m sharing five of my favorites here with you. I hope you enjoy them as much as I did. 

Felicia's book list on sci-fi featuring awesome female leads

Felicia Watson Why did Felicia love this book?

Cold Welcome is the first book in the Vatta's Peace Series by Elizabeth Moon (a sequel series to Vatta’s war), but it stands alone and can be read by a newcomer. The MC, Kylara Vatta, rejected a place in her powerful family’s space trading business and instead elected to join the military. Our war hero returns home to find not the accolades she was given to expect but an assassination attempt. The sabotage of her shuttle leaves Vatta and her crew fighting for survival, first in an icy sea and then a frozen wasteland, for history buffs this is a definite nod to Shackleton. Vatta manages to find a clandestine underground facility, which provides somewhat risky shelter for the group since the builders of the facility will do anything to keep their secrets. This is an engaging, fast-paced read; though not actually set in space, it has a classic space-opera…

Book cover of Invent and Wander: The Collected Writings of Jeff Bezos

Tom Gilb Author Of Competitive Engineering: A Handbook For Systems Engineering, Requirements Engineering, and Software Engineering Using Planguage

From my list on learning successful invention and business methods.

Why am I passionate about this?

I am a self-taught guy, having started in my first job at IBM Oslo, when I was 18 years old, as punched card machine operator, and plug-board ‘programmer'. I did night studies in sociology/philosophy for 10 years at University of Oslo. I read about 30 books a year, and I’m 82 in 2023. I have spent most of my career as an independent international consultant to corporations and governments, while building up my ideas of useful methods to solve problems. In retirement, I love to spread my ideas, and learn more. I also write about 5 new books a year, when at my Oslofjord Summer cabin. They're all digital and free or free samples.

Tom Gilb Why did Tom love this book?

No surprises. Self-made businessperson, with persistence and imagination.

This book is unusual. It is literally written by Bezos over decades of developing Amazon. It is mainly his annual reports to the shareholders! So it gives a continuous picture of the growth of the empire.

My favourite practical tip, is his executive meeting process. Meeting begins with a 6-page (with a 1-page summary) briefing, to reread for the first 20 minutes of as meeting in silence, then discussed. No presentation with slides and pretty pictures, and soothing ambiguous words.

The briefing is the result of hard work, in advance, crafting it to be useful. Wow!

Book cover of Mining the Sky: Untold Riches From the Asteroids, Comets and Planets

Martin Elvis Author Of Asteroids: How Love, Fear, and Greed Will Determine Our Future in Space

From my list on space mining.

Why am I passionate about this?

I’ve been an astronomer since I was young and lucky enough to make a living at it. I ventured into space mining when I found Mining the Sky. I started doing some calculations using the newest research. What I found was surprising and ignited a new passion in me that has led me from asteroids to the Moon to the ends of the Solar System and from pure astrophysics into questions of law, government, and ethics. Now, I write almost entirely about our future in space.

Martin Elvis Why did Martin love this book?

Nothing was more counter-intuitive to me than mining the sky. Surely, space is a void, I thought. John Lewis put me right. He convinced me–that there are huge resources out in the void that dwarf Earth’s supplies. Our future could well lie among them.

But will it be soon or centuries from now? I reckon soon.

What is this book about?

While we worry over the depletion of the earth's natural resources, the pollution of our planet, and the challenges presented by the earth's growing population, billions of dollars worth of metals, fuels, and life-sustaining substances await us in nearby space. In this visionary book, noted planetary scientist John S. Lewis explains how we can mine these precious metals from the asteroids, comets, and planets in our own solar system for use in space construction projects. And this is just one of the possibilities. Join John S. Lewis as he contemplates milking the moons of Mars for water and hollowing out…
