They mustn't harm a human being, they must obey human orders, and they must protect their own existence...but only so long as that doesn't violate rules one and two. With these Three Laws of Robotics, humanity embarked on a bold new era of evolution that would open up enormous possibilities, and unforeseen risks.

From early work like "Rescue Party" and "The Lion of Comarre", through classic stories including "The Star", "Earthlight", "The Nine Billion Names of God", and "The Sentinel" (kernel of the later novel and movie 2001: A Space Odyssey), all the way to later work like "A Meeting with Medusa" and "The Hammer of God", this comprehensive short story collection encapsulates one of the great science fiction careers of all time.

The Collected Works of Philip K. Dick is a collection of 11 science fiction stories by Philip K. Dick.

Kurt Vonnegut's first novel spins the chilling tale of engineer Paul Proteus, who must find a way to live in a world dominated by a supercomputer and run completely by machines. Paul's rebellion is vintage Vonnegut – wildly funny, deadly serious, and terrifyingly close to reality.

Traumatized by the bombing of Dresden at the time he had been imprisoned, Pilgrim drifts through all events and history, sometimes deeply implicated, sometimes a witness. He is surrounded by Vonnegut's usual large cast of continuing characters (notably here the hack science fiction writer Kilgore Trout and the alien Tralfamadorians, who oversee his life and remind him constantly that there is no causation, no order, no motive to existence).

Guy Montag is a fireman. In his world, where television rules and literature is on the brink of extinction, firemen start fires rather than put them out. His job is to destroy the most illegal of commodities, the printed book, along with the houses in which they are hidden. Montag never questions the destruction and ruin his actions produce, returning each day to his bland life and wife, Mildred, who spends all day with her television "family."

This audiobook is a collection of classic science fiction works of various authors.

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.

Bradbury's Mars is a place of hope, dreams, and metaphor - of crystal pillars and fossil seas - where a fine dust settles on the great, empty cities of a silently destroyed civilization. It is here the invaders have come to despoil and commercialize, to grow and to learn - first a trickle, then a torrent, rushing from a world with no future toward a promise of tomorrow. The Earthman conquers Mars...and then is conquered by it, lulled by dangerous lies of comfort and familiarity, and enchanted by the lingering glamour of an ancient, mysterious native race.

The richest, most depraved man on Earth, Malachi Constant, is offered a chance to take a space journey to distant worlds with a beautiful woman at his side. Of course, there's a catch to the invitation....

Only a few know the terrifying truth - an outcast Earth scientist, a rebellious alien inhabitant of a dying planet, a lunar-born human intuitionist who senses the imminent annihilation of the Sun... They know the truth - but who will listen? They have foreseen the cost of abundant energy - but who will believe?These few beings, human and alien, hold the key to the Earth's survival.

We were fighting on the wrong side of a war we couldn't win. And that was the good news. The Ruhar hit us on Columbus Day. There we were, innocently drifting along the cosmos on our little blue marble, like the native Americans in 1492. Over the horizon come ships of a technologically advanced, aggressive culture, and BAM! There go the good old days, when humans only got killed by each other. So, Columbus Day. It fits. When the morning sky twinkled again, this time with Kristang starships jumping in to hammer the Ruhar, we thought we were saved.

In the 23rd century, pioneers have escaped the crowded earth for life in self-sustaining orbital colonies. One of the colonies, Rotor, has broken away from the solar system to create its own renegade utopia around an unknown red star two light-years from Earth: a star named Nemesis. Now a 15-year-old Rotorian girl has learned of the dire threat that nemesis poses to Earth’s people - but she is prevented from warning them. Soon, she will realize that Nemesis endangers Rotor as well.

This collection comprises 40 stories by and inspired by the originators of weird fiction. From Blackwood's The Empty House, through to Philip K. Dick's The Hanging Stranger, Lovecraft's Out of The Aeons, and beyond.
