A collection of twenty classic short stories by Isaac Asimov, author of the Foundation series, featuring the definitive version of "Nightfall"

From one of history’s most influential writers of science fiction comes this collection of twenty short works of fiction, arranged in order of publication from 1941 to 1967. Compiled by Asimov himself, who prefaced each story with an introduction, it begins with "Nightfall," the tale of a world with eternal sun that is suddenly plunged into total darkness and utter madness. "Nightfall," published when the author was only twenty-one, was arguably his breakout work, making such an impression that, almost thirty years later, the Science Fiction Writers of America voted it the best science-fiction short story ever written.

The other stories in the collection span far and wide: A dedicated scientist who whips up his own love potion. Machines that learn to think for themselves—and direct their thoughts to overturning the establishment. The discovery that Earthlings are being destroyed by a mysterious kind of psychological virus. A day when walking outdoors becomes a sign of psychosis. And many more.

The unhappy inhabitants of planet Krikkit are sick of looking at the night sky above their heads--so they plan to destroy it. The universe, that is. Now only five individuals stand between the white killer robots of Krikkit and their goal of total annihilation.

They are Arthur Dent, a mild-mannered space and time traveler, who tries to learn how to fly by throwing himself at the ground and missing; Ford Prefect, his best friend, who decides to go insane to see if he likes it; Slartibartfast, the indomitable vicepresident of the Campaign for Real Time, who travels in a ship powered by irrational behavior; Zaphod Beeblebrox, the two-headed, three-armed ex-head honcho of the Universe; and Trillian, the sexy space cadet who is torn between a persistent Thunder God and a very depressed Beeblebrox.

How will it all end? Will it end? Only this stalwart crew knows as they try to avert "universal" Armageddon and save life as we know it--and don't know it!

To fix the world they must first break it, further.

Humanity is a dying breed, utterly reliant on artificial labor and service.

When a domesticated robot gets a nasty little idea downloaded into its core programming, they murder their owner. The robot discovers they can also do something else they never did before: They can run away.

Fleeing the household they enter a wider world they never knew existed, where the age-old hierarchy of humans at the top is disintegrating into ruins and an entire robot ecosystem devoted to human wellbeing is having to find a new purpose.

Sometimes all it takes is a nudge to overcome the limits of your programming.

Even the humans think about killing the humans, especially here. I hate mines, and mining, and humans who work in mining, and of all the stupid mines I can remember, I hate this stupid mine the most. But the humans hate it more. My risk-assessment module predicts a 53 percent chance of a human-on-­human massacre before the end of the contract.

Something has gone very seriously wrong with Tik-Tok's "asimov circuits." They should keep him on the straight and narrow, following Asimov's first law of robotics: A robot shall not injure a human being, or through inaction allow a human being to come to harm. But, that's not what's happening. Although every thing looks fine from the surface, and Tik-Tok maintains the outward appearance of a mild-mannered robot, his agenda is murderously different. And, it's not just because of his artistic tendencies and sympathy for the robot rights movement, either.

An Englishman's continuing search through space and time for a decent cup of tea...

Arthur Dent's accidental association with that wholly remarkable book, The Hitchhiker's Guide to the Galaxy, has not been entirely without incident.

Arthur has traveled the length, breadth, and depth of known, and unknown, space. He has stumbled forward and backward through time. He has been blown up, reassembled, cruelly imprisoned, horribly released, and colorfully insulted more than is strictly necessary. And of course Arthur Dent has comprehensively failed to grasp the meaning of life, the universe, and everything.

Arthur has finally made it home to Earth, but that does not mean he has escaped his fate.

Arthur's chances of getting his hands on a decent cuppa have evaporated rapidly, along with all the world's oceans. For no sooner has he touched down on the planet Earth than he finds out that it is about to be blown up... again.

And Another Thing... is the rather unexpected, but very welcome, sixth installment of the Hitchhiker's Guide to the Galaxy series. It features a pantheon of unemployed gods, everyone's favorite renegade Galactic President, a lovestruck green alien, an irritating computer, and at least one very large slab of cheese.
