Welcome to Ringworld, an intermediate step between Dyson Spheres and planets. The gravitational force created by a rotation on its axis of 770 miles per second means no need for a roof. Walls 1,000 miles high at each rim will let in the sun and prevent much air from escaping. Larry Niven's novel, Ringworld, is the winner of the 1970 Hugo Award for Best Novel, the 1970 Nebula Award for Best Novel, and the 1972 Ditmars, an Australian award for Best International Science Fiction.

Thousands of years ago, Earth’s terraforming program took to the stars. On the world they called Nod, scientists discovered alien life - but it was their mission to overwrite it with the memory of Earth. Then humanity’s great empire fell, and the program’s decisions were lost to time. Aeons later, humanity and its new spider allies detected fragmentary radio signals between the stars. They dispatched an exploration vessel, hoping to find cousins from old Earth. But those ancient terraformers woke something on Nod better left undisturbed. And it’s been waiting for them.

Neal Stephenson is a blazing new force on the sci-fi scene. With the groundbreaking cyberpunk novel Snow Crash, he has "vaulted onto the literary stage." It weaves virtual reality, Sumerian myth, and just about everything in between with a cool, hip cybersensibility - in short, it is the gigathriller of the information age.

The war raged across the galaxy. Billions had died, billions more were doomed. Moons, planets, the very stars themselves, faced destruction, cold-blooded, brutal, and worse, random. The Idirans fought for their Faith; the Culture for its moral right to exist. Principles were at stake. There could be no surrender. Within the cosmic conflict, an individual crusade. Deep within a fabled labyrinth on a barren world, a Planet of the Dead proscribed to mortals, lay a fugitive Mind. Both the Culture and the Idirans sought it....

Juliette, now mayor of Silo 18, doesn’t trust Silo 1, especially its leader, Donald. But in the world of the Silos, there is no black and white—everything is shades of gray. Donald may not be the monster Juliette thinks he is, and may in fact be key to humanity’s continued survival. But can they work together long enough to succeed?

I’m usually alone in my head, and that’s where 90 plus percent of my problems are. When Murderbot's human associates (not friends, never friends) are captured and another not-friend from its past requires urgent assistance, Murderbot must choose between inertia and drastic action. Drastic action it is, then.

A millennium into the future two advancements have altered the course of human history: the colonization of the galaxy and the creation of the positronic brain. Isaac Asimov's Robot novels chronicle the unlikely partnership between a New York City detective and a humanoid robot who must learn to work together. Like most people left behind on an over-populated Earth, New York City police detective Elijah Baley had little love for either the arrogant Spacers or their robotic companions.

Neal Stephenson, "the hottest science fiction writer in America", takes science fiction to dazzling new levels. The Diamond Age is a stunning tale; set in 21st-century Shanghai, it is the story of what happens what a state-of-the-art interactive device falls into the hands of a street urchin named Nell. Her life, and the entire future of humanity, is about to be decoded and reprogrammed.

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.

In the near future, the nano-drug Nexus can link mind to mind. There are some who want to improve it. There are some who want to eradicate it. And there are others who just want to exploit it. When a young scientist is caught improving Nexus, he’s thrust over his head into a world of danger and international espionage, with far more at stake than anyone realizes.

A corporate mercenary wakes in a reconstructed body, a beautiful woman by his side. Then Hosaka Corporation reactivates him, for a mission more dangerous than the one he's recovering from: to get a defecting chief of R&D-and the biochip he's perfected-out intact. But this proves to be of supreme interest to certain other parties-some of whom aren't remotely human.

En ce début de treizième millénaire, l'Empire n'a jamais été aussi puissant, aussi étendu à travers toute la galaxie. C'est dans sa capitale, Trantor, que l'éminent savant Hari Seldon invente la psychohistoire, une science nouvelle permettant de prédire l'avenir. Grâce à elle, Seldon prévoit l'effondrement de l'Empire d'ici cinq siècles, suivi d'une ère de ténèbres de trente mille ans. Réduire cette période à mille ans est peut-être possible, à condition de mener à terme son projet : la Fondation.

Autistic scientist Yasira Shien has developed a radical new energy drive that could change the future of humanity. But when she activates it, reality warps, destroying the space station and everyone aboard. The AI gods who rule the galaxy declare her work heretical, and Yasira is abducted by their agents. Instead of simply executing her, they offer mercy - if she'll help them hunt down a bigger target: her own mysterious, vanished mentor. With her homeworld's fate in the balance, Yasira must choose who to trust: the gods and their ruthless post-human angels, or a rebel scientist....

Destry's life is dedicated to terraforming Sask-E. As part of the Environmental Rescue Team, she cares for the planet and its burgeoning eco-systems as her parents and their parents did before her. But the bright, clean future they're building comes under threat when Destry discovers a city full of people that shouldn't exist, hidden inside a massive volcano. As she uncovers more about their past, Destry begins to question the mission she's devoted her life to, and must make a choice that will reverberate through Sask-E's future for generations to come.

Set against the backdrop of China's Cultural Revolution, a secret military project sends signals into space to establish contact with aliens. An alien civilization on the brink of destruction captures the signal and plans to invade Earth. Meanwhile, on Earth, different camps start forming, planning to either welcome the superior beings and help them take over a world seen as corrupt, or to fight against the invasion. The result is a science fiction masterpiece of enormous scope and vision.

Murderbot wasn’t programmed to care. So, its decision to help the only human who ever showed it respect must be a system glitch, right? Having traveled the width of the galaxy to unearth details of its own murderous transgressions, as well as those of the GrayCris Corporation, Murderbot is heading home to help Dr. Mensah—its former owner (protector? friend?)—submit evidence that could prevent GrayCris from destroying more colonists in its never-ending quest for profit. But who’s going to believe a SecUnit gone rogue? And what will become of it when it’s caught?

On Aurora, the first and greatest of the Spacer planets, Elijah Baley and R. Daneel Olivaw investigate yet another seemingly impossible crime – this time, a roboticide. Someone has destroyed the positronic mind of R. Jander Panell, a humanoid twin to Daneel. His creator, the master roboticist Han Fastolfe, denies all involvement. So does Gladia Delmarre, the robot’s owner. And lover.

Tras el misterioso hundimiento de una islita deshabitada en medio del Océano Pacífico, una expedición científica al mando del doctor Tadokoro explora el lecho submarino de la Fosa del Japón a bordo de un batiscafo capaz de descender hasta los diez mil metros de profundidad. Con la tétrica sensación de viajar recluidos en un ataúd metálico con destino a un cementerio de las profundidades, se adentrarán con su nave en unas aguas que ejercen una presión espantosa, cual monstruo imbuido de la voluntad de estrujarlos entre sus garras.

No, I didn't kill the dead human. If I had, I wouldn't dump the body in the station mall. When Murderbot discovers a dead body on Preservation Station, it knows it is going to have to assist station security to determine who the body is (was), how they were killed (that should be relatively straightforward, at least), and why (because apparently that matters to a lot of people—who knew?) Yes, the unthinkable is about to happen: Murderbot must voluntarily speak to humans! Again!

Robots are building a colossal telescope on the far side of the moon, with just two people supervising its completion. After a minor incident, these scientists become aware of an obstacle in the lunar soil. It's located outside the area reserved for the hypertelescope and is therefore none of their business. But their curiosity gets the better of them. The artifact seems to have properties that completely defy physics as they know it.
