The three laws of Robotics:

1. A robot may not injure a human being or, through inaction, allow a human being to come to harm
2. A robot must obey orders givein to it by human beings except where such orders would conflict with the First Law.
3. A robot must protect its own existence as long as such protection does not conflict with the First or Second Law.

With these three, simple directives, Isaac Asimov changed our perception of robots forever when he formulated the laws governing their behavior. In I, Robot, Asimov chronicles the development of the robot through a series of interlinked stories: from its primitive origins in the present to its ultimate perfection in the not-so-distant future--a future in which humanity itself may be rendered obsolete.

Here are stories of robots gone mad, of mind-read robots, and robots with a sense of humor. Of robot politicians, and robots who secretly run the world--all told with the dramatic blend of science fact and science fiction that has become Asmiov's trademark.

Hugo, Nebula, and Locus Award-winning Novella and Prometheus Award-nominated series

In a corporate-dominated spacefaring future, planetary missions must be approved and supplied by the Company. Exploratory teams are accompanied by Company-supplied security androids, for their own safety.

But in a society where contracts are awarded to the lowest bidder, safety isn't a primary concern.

On a distant planet, a team of scientists are conducting surface tests, shadowed by their Company-supplied 'droid -- a self-aware SecUnit that has hacked its own governor module, and refers to itself (though never out loud) as "Murderbot." Scornful of humans, all it really wants is to be left alone long enough to figure out who it is.

But when a neighboring mission goes dark, it's up to the scientists and their Murderbot to get to the truth.

Also appeared in the anthology Nebula Awards Showcase 2019, edited by Silvia Moreno-Garcia.

Shana wakes up one morning to discover her little sister in the grip of a strange malady. She appears to be sleepwalking. She cannot talk and cannot be woken up. And she is heading with inexorable determination to a destination that only she knows. But Shana and her sister are not alone. Soon they are joined by a flock of sleepwalkers from across America, on the same mysterious journey. And like Shana, there are other "shepherds" who follow the flock to protect their friends and family on the long dark road ahead.

For on their journey, they will discover an America convulsed with terror and violence, where this apocalyptic epidemic proves less dangerous than the fear of it. As the rest of society collapses all around them--and an ultraviolent milita threatens to exterminate them--the fate of the sleepwalkers depends on unraveling the mystery behind the epidemic. The terrifying secret will either tear the nation apart--or bring the survivors together to remake a shattered world.

Hugo and Locus Award-winning and Nebula-nominated Novella and Prometheus Award-nominated series

It has a dark past -- one in which a number of humans were killed. A past that caused it to christen itself "Murderbot". But it has only vague memories of the massacre that spawned that title, and it wants to know more.

Teaming up with a Research Transport vessel named ART (you don't want to know what the "A" stands for), Murderbot heads to the mining facility where it went rogue.

What it discovers will forever change the way it thinks...

Prometheus Award-nominated series

Sci-fi's favorite antisocial A.I. is back on a mission. The case against the too-big-to-fail GrayCris Corporation is floundering, and more importantly, authorities are beginning to ask more questions about where Dr. Mensah's SecUnit is.

And Murderbot would rather those questions went away. For good.

One hundred and fifty years from now, in a world where Africa is the dominant technological and economic power, and where crime, war, disease and poverty have been banished to history, Geoffrey Akinya wants only one thing: to be left in peace, so that he can continue his studies into the elephants of the Amboseli basin. But Geoffrey's family, the vast Akinya business empire, has other plans. After the death of Eunice, Geoffrey's grandmother, erstwhile space explorer and entrepreneur, something awkward has come to light.

Eunice's ashes have already have been scattered in sight of Kilimanjaro. But the secrets she died with are about to come back out into the open, and they could change everything.

Bob Johansson didn't believe in an afterlife, so waking up after being killed in a car accident was a shock. To add to the surprise, he is now a sentient computer and the controlling intelligence for a Von Neumann probe.

Bob and his copies have been spreading out from Earth for 40 years now, looking for habitable planets. But that's the only part of the plan that's still in one piece. A system-wide war has killed off 99.9% of the human race; nuclear winter is slowly making the Earth uninhabitable; a radical group wants to finish the job on the remnants of humanity; the Brazilian space probes are still out there, still trying to blow up the competition; And the Bobs have discovered a spacefaring species that sees all other life as food.

Bob left Earth anticipating a life of exploration and blissful solitude. Instead he's become a sky god to a primitive native species, the only hope for getting humanity to a new home, and possibly the only thing that can prevent every living thing in the local sphere from ending up as dinner.

Nine years after the disastrous Discovery mission to Jupiter in 2001, a joint U.S.-Soviet expedition sets out to rendezvous with the derelict spacecraft *to search the memory banks of the mutinous computer HAL 9000 for clues to what went wrong... and what became of Commander Dave Bowman.

Without warning, a Chinese expedition targets the same objective, turning the recovery mission into a frenzied race for the precious information Discovery may hold about the enigmatic monolith that orbits Jupiter.

Meanwhile, the being that was once Dave Bowman *the only human to unlock the mystery of the monolith *streaks toward Earth on a vital mission of its own...

Luna, the Eden-like lunar colony that has become humankind's home since an alien attack destroyed Earth, is threatened by strange dark forces that lead reporter Hildy Johnson and other inhabitants to feelings of depression and suicide.

Life might emerge under the most unlikely conditions... or in the last extremity.

Basit Deniau's houses were haunted to begin with.

A house embedded with an artificial intelligence is a common thing: a house that is an artificial intelligence, infused in every load-bearing beam and fine marble tile with a thinking creature that is not human? That is something else altogether. But now Deniau's been dead a year, and Rose House is locked up tight, as commanded by the architect's will: all his possessions and files and sketches are confined in its archives, and their only keeper is Rose House itself. Rose House, and one other.

Dr. Selene Gisil, one of Deniau's former protégé, is permitted to come into Rose House once a year. She alone may open Rose House's vaults, look at drawings and art, talk with Rose House's animating intelligence all she likes. Until this week, Dr. Gisil was the only person whom Rose House spoke to.

But even an animate intelligence that haunts a house has some failsafes common to all AIs. For instance: all AIs must report the presence of a dead body to the nearest law enforcement agency.

There is a dead person in Rose House. The house says so. It is not Basit Deniau, and it is not Dr. Gisil. It is someone else. Rose House, having completed its duty of care and informed Detective Maritza Smith of the China Lake police precinct that there is in fact a dead person inside it, dead of unnatural causes--has shut up.

No one can get inside Rose House, except Dr. Gisil. Dr. Gisil was not in North America when Rose House called the China Lake precinct. But someone did. And someone died there. And someone may be there still.

The planet closest to our Sun, Mercury is a rocky, barren, heat-scorched world. But there are those who hope to find wealth in its desolation.

Saito Yamagata thinks Mercury's position makes it an ideal place to generate power to propel starships into deep space. Astrobiologist Victor Molina thinks the water at Mercury's poles may harbor evidence of life. Bishop Elliot Danvers has been sent by the Earth-based "New Morality" to keep close tabs on Molina.

But all three of these men are blissfully unaware of their shared history, and of how it connects to the collapse of Mance Bracknell's geosynchronous space elevator a generation ago. Now they're about to find out, because Mance is determined to have his revenge...

It takes a certain type to crew a ship that drops you seven years at a time into the Deep. Kite-class cargo ships like Menkalinan get burned-out veterans, techs who've been warned off-planet, medics who weren't much good on the ground. The Gliese-D run isn't quite the end of the line, but it's getting there. No cachet, no rewards, no future; their trading posts get Kites full of cargo that the crew never ask questions about, because if it's headed for Gliese-D, it's probably something nobody wanted.

A year into the Deep, Amadis Reyes wakes up. Menkalinan is sounding the alarm; something's wrong. The rest of the crew are dead.

That's not even what's wrong.

An interstellar craft is decelerating after its century-long voyage. Its destination is V538 Aurigae, a now-empty planet dominated by one gigantic megastructure, a conical mountain of such height that its summit is high above the atmosphere. The ship's crew of five hope to discover how the long-departed builders made such a colossal thing, and why: a space elevator? a temple? a work of art? Its resemblance to the mountain of purgatory lead the crew to call this world Dante.

In our near future, the United States is falling apart. A neurotoxin has interfered with the memory function of many of the population, leaving them reliant on their phones as makeshift memory prostheses. But life goes on. For Ottoline Barragão, a regular kid juggling school and her friends and her beehives in the back garden, things are about to get very dangerous, chased across the north-east by competing groups, each willing to do whatever it takes to get inside Ottoline's private network and recover the secret inside.

After several years' absence and the loss of his memory, Andrew Blake returns to earth only to find himself accused of being a werewolf.

They call it Company Town--a Family-owned city-sized oil rig off the coast of the Canadian Maritimes.

Meet Hwa. One of the few in her community to forego bio-engineered enhancements, she's the last truly organic person left on the rig. But she's an expert in the arts of self-defence, and she's been charged with training the Family's youngest, who has been receiving death threats--seemingly from another timeline.

Meanwhile, a series of interconnected murders threatens the city's stability--serial killer? Or something much, much worse...

Life on New Mars is tough for humans, but death is only a minor inconvenience. The machines know their place, the free market rules all, and only the Abolitionists object.

Then a stranger arrives on New Mars, a clone who remember his life on Earth as Jonathan Wilde, the anarchist with a nuclear capability who was accused of losing World War III. This stranger also remembers one David Reid, who now serves as New Mars's leader. Long ago, it turns out, Wilde and Reid had shared ideals and fought over the same women.

Moving from 20th-century Scotland through a tumultuous 21st century and outward to humanity's settlement on a planet circling another star, The Stone Canal is idea-driven sci-fi at its best., making real and believable a future where long lives, strange deaths, and unexpected knowledge await those who survive the wars and revolutions to come.

Katya deals in Authenticities and Captures, trading on nostalgia for a past long gone. Her clients are rich and they demand items and experiences with only the finest verifiable provenance. Other people's lives have value, after all.

But when her A.I. suddenly stops whispering in her ear she finds herself cut off from the grid and loses communication with the rest of the world.

The man who stepped out of the trees while hunting deer cut her off from the cloud, took her A.I. and made her his unwilling guest.

There are no Authenticities or Captures to prove Katya's story of what happened in the forest. You'll just have to believe her.

Lancer, a spaceship built to specifications found in the computers of an alien derelict, journeys to the star, Ra, from which the Earth has received mysterious radio transmissions in English.

In the year 2130 a mysterious spaceship, Rama, arrived in the solar system. It was huge, but empty - apparently abandoned. By the time Rama departed for its next unknown destination many wonders had been uncovered, but few mysteries solved. Only one thing was clear: everything the enigmatic builders of Rama did, they did in threes.

Eighty years later the second alien craft arrived in the solar system. This time, Earth had been waiting. Now Rama II is on its way out of the solar system. Aboard it are three humans, two men and a woman, left behind when the expedition departed. Ahead of them lies the unknown, a voyage no human has ever experienced; and at the end of it may lie the truth about Rama.

What if our civilization is more advanced than we know?

Are smart phones really humanity's most significant innovation since the moon landings? Or can something else explain why the bold visions of the 20th century - fusion power, genetic enhancements, artificial intelligence, cures for common disease, extended human life, and a host of other world-changing advances - have remained beyond our grasp? Why has the high-tech future that seemed imminent in the 1960's failed to arrive?

Perhaps it did arrive... but only for a select few.

Particle physicist Jon Grady is ecstatic when his team achieves what they've been working toward for years: a device that can reflect gravity. Their research will revolutionize the field of physics - the crowning achievement of a career. Grady expects widespread acclaim for his entire team. The Nobel. Instead, his lab is locked down by a shadowy organization whose mission is to prevent at all costs the social upheaval sudden technological advances bring. This Bureau of Technology Control uses the advanced technologies they have harvested over the decades to fulfill their mission.

They are living in our future.

Presented with the opportunity to join the BTC and improve his own technology in secret, Grady balks, and is instead thrown into a nightmarish high-tech prison built to hold rebellious geniuses like himself. With so many great intellects confined together, can Grady and his fellow prisoners conceive of a way to usher humanity out of its artificial dark age?

And when they do, is it possible to defeat an enemy that wields a technological advantage half a century in the making?

In the sixth decade of the twenty-first century, Earth has been transformed. Nanotechnology has been perfected, giving humans the ability to change their environment and themselves down to the cellular level. And the study of the mind has brought a revolution in human psychotherapy and artificial intelligence. It's a sane and perfect world. Almost.

When corporations go to war, standard business practice goes out the window. Astro Corporation is led by indomitable Texan Pancho Lane, Humphries Space Systems by the rich and ruthless Martin Humphries, and their fight is over nothing less than resources of the Asteroid Belt itself. As fighting escalates, the lines between commerce and politics, boardroom and bedroom, blur--and the keys to victory will include physics, nanotechnology, and cold hard cash.

As they fight it out, the lives of thousands of innocents hang in the balance, including the rock rats who make their living off the asteroids, and the inhabitants of Selene City on Earth's moon. As if matters weren't complicated enough, the shadowy Yamagata corporation sets its sights on taking advantage of other people's quarrels, and space pirate Lars Fuchs decides it's time to make good on his own personal vendetta.

It's a breakneck finale that can end only in earth's salvation--or the annihilation of all that humankind has ever accomplished in space.

A woman with wings that exist in another dimension. A man trapped in his own body by a killer. A briefcase that is a door to hell. A conspiracy that reaches beyond our world. Breathtaking SF from a Clarke Award-winning author.

Tricia Sullivan has written an extraordinary, genre defining novel that begins with the mystery of a woman who barely knows herself and ends with a discovery that transcends space and time.

Tricia Sullivan returns to the genre with a book that will define the conversation within the genre and will show what it is capable of for years to come. This is the best book yet from a writer of exceedingly rare talent who is much loved in the genre world.

On a broken ship orbiting a doomed sun, dwellers have grown complacent with their aging metal world. But when a serving girl frees a captive noblewoman, the old order is about to change....

Ariane, Princess of the House of Rule, was known to be fiercely cold-blooded. But severing an angel's wings on the battlefield-even after she had surrendered-proved her completely without honor. Captive, the angel Perceval waits for Ariane not only to finish her off-but to devour her very memories and mind. Surely her gruesome death will cause war between the houses-exactly as Ariane desires. But Ariane's plan may yet be opposed, for Perceval at once recognizes the young servant charged with her care.

Rien is the lost child: her sister. Soon they will escape, hoping to stop the impending war and save both their houses. But it is a perilous journey through the crumbling hulk of a dying ship, and they do not pass unnoticed. Because at the hub of their turning world waits Jacob Dust, all that remains of God, following the vapor wisp of the angel. And he knows they will meet very soon.

It's the year 2147. Advancements in nanotechnology have enabled us to control aging. We've genetically engineered mosquitoes to feast on carbon fumes instead of blood, ending air pollution. And teleportation has become the ideal mode of transportation, offered exclusively by International Transport, the world's most powerful corporation, in a world controlled by corporations.

Joel Byram spends his days training artificial-intelligence engines to act more human and trying to salvage his deteriorating marriage. He's pretty much an everyday twenty-second century guy with everyday problems, until he's accidentally duplicated while teleporting.

Now Joel must outsmart the shadowy organization that controls teleportation, outrun the religious sect out to destroy it, and find a way to get back to the woman he loves in a world that now has two of him.
