Brave New World

By Aldous Huxley

The genius of Brave New World’s dystopia lies in how much it sounds (on paper) like the perfect society: everyone is happy (due to the drug soma), old age is no longer a problem, sexual freedom is embraced, and ills like poverty and disease have mostly been eradicated. It takes John, a young man who grew up in exile, to see how terribly empty this life is. But rather than being welcome as a savior, he becomes an oddity.

At the Mountains of Madness

At the Mountains of Madness

By H. P. Lovecraft

Though usually classified as a horror tale, Mountains is really a scientific expedition into the unknown gone terribly wrong. Lovecraft’s attention to archaeology, human history, and the practicalities of exploring the inhospitable Antarctic make it a tale of survival and science, but all of that is just the prelude for a chain of revelations that are horrifying not because they involve monstrous creatures, but because their terrifying implications for humanity are almost too much to bear.

1984

By George Orwell

It’s hard to find anyone who hasn’t heard of Orwell’s magnum opus, but to truly understand the depth, subtlety, and prescience of the novel, multiple readings are recommended. 1984 isn’t just about surveillance, misinformation, or even government control—it’s about a society that operates on a reality as malleable as our own minds. Chilling, incisive, and thought-provoking, 1984 always seems to loom large on the horizon, threatening to slip into reality.

I, Robot

By Isaac Asimov

In many ways, we’re still catching up to the stories in I, Robot, which seem poised to become as real and troubling as anything in HBO’s Westworld. Spanning the decades-long rise of U.S. Robotics, the stories chronicle the accelerating advancement of thinking machines, bookended by interviews with Susan Calvin, the now-aged robopsychologist who watched them transform from mute, bipedal automatons into nation-guiding supercomputers. At the heart of it all is the famous Three Laws of Robotics…and the question of what makes a robot.

The Martian Chronicles

By Ray Bradbury

Though Bradbury’s legendary Martian Chronicles lacks the scientific chops of other sci-fi classics, it’s definitely got variety, imagination, and heart. The book is a collection of short stories and vignettes united into a sprawling narrative that chronicles the human colonization of Mars, which is already populated by the human-like, telepathic Martians. Some stories are humorous, some are melancholy, but taken as a whole, the book creates a surprisingly poignant portrait of humanity.

Foundation

By Isaac Asimov

Instead of recounting a single lifetime or even a generation, Foundation chronicles the tipping points of a galactic civilization. The main character, psychohistorian Hari Seldon, has modeled the course of humanity and discovered that, through subtle nudges, a select group of people can save our race from an inevitably approaching millennia-long dark age. So begins one of the most sprawling, thoughtful epics in sci-fi, which has inspired everyone from Elon Musk to Nobel-winner Paul Kruggman.

Starship Troopers

By Robert A. Heinlein

The poster child for military sci-fi, Starship Troopers is relentlessly realistic, down to its protagonist Johnny Rico’s stomach dropping as his orbital pod plummets to a new planet, where he fights against the ravenous giant aliens known as the Bugs. A major part of the book’s legacy is powered armor, which turns the soldier of the future into a walking tank and becomes the focus for Troopers’ exciting, large-scale battles against the aliens.

Canticle for Leibowitz

By Walter M. Miller Jr.

Canticle takes place after a nuclear war has devastated the Earth and a small monastic order has risen to preserve books, where are being destroyed by Luddite-like mobs who blame science and learning for allowing humanity to destroy itself. Post-apocalyptic landscapes and century-spanning narratives are nothing new to sci-fi, but Canticle marries both elements to create one of the most poignant, enduring tales of humanity’s rise and fall.

1961

Stranger in a Strange Land

By Robert A. Heinlein

Stranger in a Strange Land is about a young man named Smith, raised on Mars by Martians after surviving a failed expedition, and his return to the home planet he never knew. Smith instantly becomes a celebrity, but as he reveals his radical new understanding of life (and Martian psychic powers), he starts butting heads with the massive, influential new religions that have begun guiding human society. Eclectic, imaginative, and still powerful decades later.

1961

Catseye

Catseye

By Andre Norton

In an age when the rights and sentience of robots dominates the zeitgeist, it’s easy to forget that the question of animal rights and intelligence has been explored for years in sci-fi stories like Catseye. The book focuses on Troy, one of the few people who can communicate with animals telepathically, and a cast of creatures being modified and sold as pets (and living weapons). As the story goes on, Troy begins fighting with his animal partners against a system that sees them as tools, rather than lives.

Solaris

By Stanislaw Lem

Solaris takes place in orbit around the titular planet, which is covered by an ocean discovered to be a single, massive alien intelligence. Scientists are baffled by the ocean’s true nature, but the protagonist, psychologist Kris Kelvin, arrives to try to gain some insight. After a radical experiment, however, the crew begin to see visions pulled from their deepest, darkest feelings, suggesting that though humans may not understand Solaris, it might understand us.

The Man in the High Castle

By Philip K. Dick

Philip K. Dick’s famous alternate history novel doesn’t just explore what would have happened if the Axis powers had won World War II—it explores reality, the nature of fiction, and the divide between cultures. The society and colonial life of the Imperial Japanese territories in America are described in amazing depth, but the book’s real goal is using its premise as entrée to ask more troubling questions: what is fake, what is real, and how can we tell?

Hothouse

Hothouse

By Brian W. Aldiss

Hothouse is built on a series of ideas so bizarre and imaginative that you can’t help but get hooked: what if the Earth’s climate became so warm that plants wiped out nearly all other life? What if these plants began to gain limited intelligence, even limbs and eyes? What if spiders connected the Earth to the Moon with giant webs? What it lacks in scientific credibility, Hothouse makes up for in sheer weirdness.

Way Station

Way Station

By Clifford D. Simak

Way Station follows Enoch Wallace, a Civil War soldier who is chosen to become the station-master for a futuristic teleportation facility run by aliens. Beneath this initially strange premise, however, is a story of an ageless man learning to make friends with myriad strangers from civilizations among the stars. Refreshingly, Way Station’s optimism and empathy stands in stark contrast to other alien contact stories that focus on the paranoia and culture shock of meeting beings from other worlds.

Dune

By Frank Herbert

In the constellation of sci-fi classics, Dune’s star shines among the very brightest. The book offers almost unparalleled worldbuilding (down to planetary ecology), but most impressive of all is its ability to boil down a galaxy-spanning war, millennia-long prophecy, and planet-wide rebellion into the story of Paul Atreides, a young man pulled by the currents of history into becoming a new Messiah. Filled with mysticism, intrigue, and truly epic stakes, Dune is a saga in itself.

Babel-17

Babel-17

By Samuel R. Delany

Like a lot of classic sci-fi from the 1960s, Babel-17 is a story based on a big idea—specifically, the Sapir-Whorf hypothesis, the theory that one’s language has the power to shape one’s perceptions and experiences. The story focuses on the titular Babel-17, a language developed by an alien race as a subtle weapon to warp the perceptions of their human enemies and turn them into saboteurs and traitors. A stimulating dive into language, reality, and human will.

2001: A Space Odyssey

By Arthur C. Clarke

Although you can read 2001 simply to understand the more cryptic elements of Stanley Kubrick’s film masterpiece, the book stands on its own as a genuinely engrossing and mind-expanding saga, exploring artificial intelligence and human evolution. The book is filled with meticulous scientific detail, enough to please any fan of truly well-researched hard sci-fi. As for the plot, it begins with the mysterious arrival of a black monolith on Earth…

Do Androids Dream of Electric Sheep?

By Philip K. Dick

Though now it owes most of its notoriety to its film adaptation, Blade Runner, Androids is arguably the most compelling story to come from the mind of Philip K. Dick. It follows Rick Deckard, a detective who must hunt down six escaped androids that appear totally human…except for a chilling lack of empathy. Exploring the near-empty, post-space-colonization Earth, as well as the twisted psychology of the androids themselves, Androids is an excellent example of Dick’s unique brand of strange and uncanny sci-fi.

The Left Hand of Darkness

By Ursula K. Le Guin

The Left Hand of Darkness isn’t just a breakthrough moment for the sci-fi genre, it’s an enduring piece of feminist speculative fiction. Still lauded decades after its release, the book is about an envoy named Genly Ai who is sent on a mission to the Gethenians, a race of ambisexual aliens. Ai’s experiences on the journey cause him to question his perceptions of society and self, and his unexpected friendship with a Gethenian Estraven opens his mind to the otherwise alien race.

A Boy and His Dog

A Boy and His Dog

By Harlan Ellison

The vivid post-apocalyptic setting in Boy is perfectly reflected in its 15-year-old main character: brutal, lawless, and amoral. Still, the most poignant thing about the “boy” is that there’s still some child-like innocence shining through his cracks, which is carefully tended by Blood, his hyper-intelligent telepathic dog companion. Their relationship is the heart of the story, and evokes a simpler time when a kid and his dog could roam around without having to kill people.

Tau Zero

Tau Zero

By Poul Anderson

Tau Zero’s premise is at once simple and terrifying: what if you were trapped in a spaceship that kept accelerating forever? This is the fate of the crew of the Leonora Christine, a ship sent out to colonize another world, propelled by an engine called a Bussard ramjet. In addition to delving into the hard science aspects of its story, Tau Zero takes time to explore the personalities and conflicts of the crew as they become ever-more distant from Earth and the normal flow of time.

Ringworld

By Larry Niven

The chief selling point of this ‘70’s classic is the titular Ringworld, the colossal ring-shaped space habitat that’s captured the imaginations of decades of science-fiction fans. The tremendous scale and wonder of exploring the station are enough to carry you along with the story’s small cast of characters: Louis, a near-ageless human in search of adventure, Nessus, a bizarre alien called a puppeteer, Speaker-to-Animals, a cat-like alien, and Teela Brown, a young woman.

The Forever War

The Forever War

By Joe Haldeman

Despite being one of the founding books of the military sci-fi genre, The Forever War is the opposite of what you’d expect: instead of a bloody thriller, it’s a thought-provoking, heart-wrenching tale about soldiers set adrift by a war that never seems to end. Due to the time dilation caused by faster-than-light trips to fight in far-flung systems, the book’s protagonist, William Mandella, returns to Earth after multiple tours of duty to find his home planet is no longer ‘home.’

The Dispossesed

By Ursula K. Le Guin

Though The Dispossessed is classified as utopian sci-fi, the book has much more on its mind than simply laying out the blueprint for its fictional society, Anarres. Through its physicist protagonist Shevek, Le Guin explores the nature of time (which shapes the structure of the story itself), freedom, politics, morality, and capitalism, in part by comparing two neighboring planets: the strictly hierarchical Urras and the anarchical Anarres. Years after its release, The Dispossessed is heady, intelligent, and still timely.

The Mote in God's Eye

By Larry Niven & Jerry Pournelle

A classic of 1970s sci-fi, Mote tells the tale of first contact between humans and an alien race dubbed the Moties, who are residents of the titular “Mote in God’s Eye,” a star system near a red giant star. The Moties seem peaceful, civilized, and relatively friendly, but as the crew of the starship MacArthur considers allowing them to join humanity’s star-spanning empire, they realize that these aliens have a dark secret…

The Female Man

The Female Man

By Joanna Russ

In one of the first modern pieces of feminist sci-fi, an average woman from 1970s America meets three other versions of herself scattered across multiple dimensions: a futuristic utopia, a bleak version of the past, and a world in an ongoing war between men and women. Hard questions are raised, including what female empowerment looks like and how women should relate to one another. Radical and unapologetic, it’s a milestone in sci-fi’s ongoing discussion of gender and womanhood.

1979

The Fountains of Paradise

The Fountains of Paradise

By Arthur C. Clarke

Even 40 years later, Fountains remains a prophetic piece of sci-fi as monumental as its centerpiece, a 22,000-mile-long space elevator dubbed the Tower. Apart from mega-engineering, the book touches on interplanetary colonization, terraforming, ancient history, and the slow transformation of the Earth into an uninhabitable wasteland. Fountains is as much a story of technology and humanity as it is a chronicle of its protagonist, Vannevar Morgan, and its sheer scope is enough to induce vertigo.

Hitchhiker's Guide to the Galaxy

By Douglas Adams

Hitchhiker’s Guide became famous by going all-in on its unabashedly absurd sense of humor, but its decades-long staying power comes from its unique ability to capture just how vast (and potentially alien) the universe is. Hitchhiker’s revels in the knowledge that we are all just tiny specks in a swirling cosmos, so why take life so seriously? Why not feature an alien named Ford Prefect, the two-headed President of the Galaxy, and a man with a towel as the protagonists?

The Book of the New Sun

By Gene Wolfe

The Book of the New Sun is not for those wishing for an easy read (entire articles have been written about how to even get into it), but for readers who are willing to dig in, it offers an experience unlike anything else in the genre. A unique blend of fantasy and sci-fi, the story follows Severian, a member of the Executioner’s Guild, on his journey in exile.

1983

Eon

Eon

By Greg Bear

On its face, Eon’s premise is a familiar one: a massive alien structure appears near Earth, both Eastern and Western superpowers want to control it, and a brilliant scientist is caught in the middle. Eon, however, is a lot more ambitious in scope than that—as the story unfolds, it deals with human augmentation, digital resurrection, multiple timelines, and alien invasion. It’s also the beginning of a mind-bending sci-fi series, titled “The Way.”

1984

Neuromancer

By William Gibson

Apart from being the book that kickstarted cyberpunk, Neuromancer is still arguably the greatest novel in the genre: between its vivid prose, incredibly elaborate worldbuilding, fast-moving pacing, and a plot that twists the mind into 4D pretzels, Neuromancer has rightly been called a watershed in sci-fi. The more its washed-up hacker protagonist, Case, delves into the book’s conspiracies, secret projects, black market tech, and corporate espionage, the more mind-blowing the narrative becomes.

Contact

By Carl Sagan

Written by the beloved science icon Carl Sagan, Contact is one of the more plausible, scientifically rigorous portrayals of first contact with aliens, grounded in Sagan’s lifelong love of physics, math, and astronomy. The plot kicks into gear with SETI picking up messages from Vega, a distant star system, which are eventually translated into instructions to build a mysterious machine. Contact is recommended for anyone looking to expand their mind while exploring the possibility of alien life.

Ender's Game

By Orson Scott Card

Read by young adults and Marine Corps recruits alike, Ender’s Game is arguably the most popular sci-fi novel ever penned. Following the young tactical genius “Ender” Wiggins through his training as a starship commander in preparation for the ongoing war against the alien race known as the “buggers,” the book rises above other military sci-fi with excellent action, strong characterization, and an absolutely devastating ending.

The Falling Woman

The Falling Woman

By Pat Murphy

The Falling Woman is a more subtle take on sci-fi, but its honesty when it comes to human relationships makes it just as satisfying. The protagonist, Elizabeth Butler, is an archaeologist studying the ruins of an ancient Mayan city, but there’s a twist: Butler can see the spirits of the dead at dawn and dusk. Immersed in her work and the past of the Mayans, her life is interrupted by the sudden arrival of her estranged daughter, Diane.

Red Mars

By Kim Stanley Robinson

The Martian got a lot of attention for bringing the harsh realities of living on Mars to life, but Kim Stanley Robinson’s Red Mars is on a whole other level: charting the colonization, terraforming, and development of Mars into a true home for humans, the book delves into all the complicated questions that come with settling other planets. As one of the most acclaimed hard sci-fi writers alive, Robinson’s attention to science, geo-politics, and near-future tech makes Red Mars a captivating read.

Snow Crash

By Neal Stephenson

A pillar of the cyberpunk genre, Snow Crash bears all of Neal Stephenson’s hallmarks: stylish prose, inventive sci-fi elements, and long digressions into weird, fascinating esoterica. Snow Crash’s narrative centers on a virus that can not only crash computer systems but rewrite the human brain, though Stephenson doesn’t really want you to take the rest of the novel’s plot too seriously (Exhibit A: its main character is Hiro Protagonist).

Jurassic Park

By Michael Crichton

Truly a book that needs no introduction, Jurassic Park exemplifies how hard sci-fi can capture the imagination of readers across generations. Featuring Michael Crichton’s signature blend of popular science and thriller-style writing, Jurassic Park’s main attraction is (of course) the dinosaurs—not just their behavior or violence, but the wonder of seeing giant, vanished creatures from another age…and realizing how dangerous it is to play God.

Parable of the Sower

Parable of the Sower

By Octavia E. Butler

In Parable, Butler’s dystopian America suffers from a unique combination of climate change, corporate takeover, government breakdown, and drug-fueled chaos. The book revolves around its black teenage protagonist, an empath who is looking to spread a new religion called Earthseed, which embraces change and encourages humanity’s spread to other planets. Since its release, the book’s Afrofuturist exploration of religion, environmentalism, and society has carved out a niche both in pop culture and the greater sci-fi canon.

The Diamond Age

By Neal Stephenson

Though Diamond Age contains enough material to fill several popular science books (including hyper-advanced nanotechnology and matter compilers), the book’s genius lies in weaving all those elements together in mesmerizing ways. As always, Stephenson’s worldbuilding is incredibly immersive, and one of the highlights of the book is watching the young protagonist Nell try to survive and navigate the landscape and cultures of New Chusan (with the help of the titular Primer, of course).

After working out a shady deal, he begins an investigation into the apparent suicide of a near-ageless billionaire. Action-packed and outfitted with captivating new twists on sci-fi concepts (ranging from digital consciousness to neurological implants), Altered Carbon is a twisty, futuristic mystery that relishes its intricate world and technology.

World War Z

Like most good zombie fiction, World War Z is less about the walking dead and more about how they reveal the cracks in our society. Presented as a series of oral interviews with survivors in the wake of the undead apocalypse, World War Z is a deceptively subtle, insightful journey into humanity’s collective heart of darkness, as well as a vivid, incredibly well-researched portrayal of a global nightmare. The end product is a stunning mosaic of humanity at is best, worst, and most desperate.

Enter Emiko, a biologically engineered person abandoned on the streets of Bangkok. A stunningly complex, immersive world gives way to an unvarnished portrayal of humanity at its most brutal.

The Three-Body Problem

By Cixin Liu

The first major piece of Chinese sci-fi to break into American pop culture, Three Body Problem weaves together mathematics, nanotechnology, virtual reality, and Chinese history to create a surprisingly dark alien contact narrative: what if someone found out a war-like alien civilization was on the verge of finding Earth...and decided to invite them here? Three Body’s plot is studded with big ideas and futuristic tech, but it’s set in motion by the cruelest, darkest chapters of the Chinese Revolution.

All Systems Red

By Martha Wells

This book is worth picking up just from its description: a security android manages to override its own programming, dubbing itself ‘Murderbot’ and deciding to kill the human scientists it was assigned to protect…before it becomes distracted by streaming endless TV shows. Told through the misanthropic inner thoughts of Murderbot (including thoughtful, if snarky, reflections on the humans and its own personality) the book is both laugh-out-loud funny and a surprisingly honest depiction of an introvert coming to terms with themselves.
