For millions of years, the part of the galaxy containing our solar system has been moving through a vast force field that has been inhibiting certain electromagnetic and electrochemical processes and, thus, certain neurotic functions. When Earth escapes the inhibiting field, synapse speed immediately increases, causing a rise in intelligence, which results in a transfigured humanity reaching for the stars, leaving behind our earth to the less intelligent humans and animal life-forms.

Think there's an unbridgeable gulf between human and alien thought? Not so! There's a common tongue, all right - and Nicholas Van Rijn speaks it fluently: trade. For behind the buffoonish blarney and bawdy bonhomie of the Falstaffian Van Rijn is a man who gets things done. A born wheeler-dealer who usually leaves both sides better off in the bargain. (While pocketing a hefty cut of the profits himself, of course!)

In the 20th century Earth sent probes, transmissions, and welcoming messages to the stars. Unfortunately, someone noticed. The Galactics arrived with their battle fleet in 2052. Rather than being exterminated under a barrage of hell-burners, Earth joined their vast Empire. Swearing allegiance to our distant alien overlords wasn't the only requirement for survival. We also had to have something of value to trade, something that neighboring planets would pay their hard-earned credits to buy. As most of the local worlds were too civilized to have a proper army, the only valuable service Earth could provide came in the form of soldiers....

Amber is the one real world, of which all others including our own Earth are but Shadows. Amber burns in Corwin's blood. Exiled on Shadow Earth for centuries, the prince is about to return to Amber to make a mad and desperate rush upon the throne.

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.

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.

At first, only a few things are known about the celestial object that astronomers dub Rama. It is huge, weighing more than ten trillion tons. And it is hurtling through the solar system at inconceivable speed. Then a space probe confirms the unthinkable: Rama is no natural object. It is, incredibly, an interstellar spacecraft. Space explorers and planet-bound scientists alike prepare for mankind's first encounter with alien intelligence.

Get ready to experience two more origin stories in the Backyard Starship universe.

The Mote In God's Eye is their acknowledged masterpiece, an epic novel of mankind's first encounter with alien life that transcends the genre. No lesser an authority than Robert A. Heinlein called it "possibly the finest science fiction novel I have ever read".

Nine hundred thousand years ago, something annihilated the Amarantin civilization just as it was on the verge of discovering space flight. Now one scientist, Dan Sylveste, will stop at nothing to solve the Amarantin riddle before ancient history repeats itself. With no other resources at his disposal, Sylveste forges a dangerous alliance with the cyborg crew of the starship Nostalgia for Infinity. But as he closes in on the secret, a killer closes in on him because the Amarantin were destroyed for a reason.

In a distant galaxy of colonized planets, the atrocity of slavery is alive and well. Young Thorby was just another bedraggled orphan boy sold at auction, but his new owner, Baslim, is not the disabled beggar he appears to be. Adopting Thorby as his son, Baslim fights relentlessly as an abolitionist spy. When the authorities close in on Baslim, Thorby must find his own way in a hostile galaxy. Joining with the Free Traders, a league of merchant princes, Thorby must find the courage to live by his wits and fight his way up from society's lowest rung.

In AD 2600, the human race is finally beginning to realize its full potential. Hundreds of colonized planets scattered across the galaxy host a multitude of prosperous and wildly diverse cultures. Genetic engineering has pushed evolution far beyond nature's boundaries, defeating disease and producing extraordinary spaceborn creatures. Huge fleets of sentient trader starships thrive on the wealth created by the industrialization of entire star systems, and throughout inhabited space the Confederation Navy keeps the peace.

Two centuries after the Confederation staved off an invasion by the robotic Locusts, Captain Jack Romanoff faces mandatory retirement from an ever-shrinking navy. Actions speak louder than words. The Confederation doesn’t think the Locusts are coming back. But what if the politicians are wrong?

The Interbeing League had been formed to make contact with new intelligent races in the galaxy and offer them membership. But when the League encountered the Hokas, furry creatures strongly resembling the teddy bears of Earth, the league's agent, Alexander Jones, could have been excused for wishing he had a simpler assignment than making sense out of the Hokas - such as singlehandedly stopping an interstellar war.

With "wonderfully logical detail...exciting storytelling and moving characterization" (Anthony Boucher), science fiction master Poul Anderson explores what happens when the next stage of evolution is thrust upon humanity and animals. As Earth passes out of a magnetic field that has suppressed intelligence for eons, the mental capacity for all mammals increases exponentially, radically changing the structures of society.

Others have written science fiction on the theme of immortality, but in The Boat of a Million Years, Poul Anderson made it his own. Early in human history, certain individuals were born who live on—unaging, undying—through the centuries and millennia. This story follows them over two thousand years, up to our time and beyond—to the promise of utopia, and to the challenge of the stars.

The very far future: The galaxy is a drifting wreck of black holes, neutron stars, and chill white dwarfs. The age of star formation is long past. Yet there is life here, feeding off the energies of the stellar remnants, and there is mind, a tremendous galaxy-spanning intelligence each of whose thoughts lasts a hundred thousand years. And this mind cradles memories of a long-gone age when a more compact universe was full of light... The 27th century: Proxima Centauri, an undistinguished red dwarf star, is the nearest star to our sun. How would it be to live on such a world?

Artificial intelligence has been developed to a point where human intelligence can be uploaded into a computer, achieving a sort of hybrid immortality. Astronaut Christian Brannock welcomes this technology, technology that will make it possible for him to achieve his dream and explore the stars.

The Ship fled a dying Earth to save the human race. Launched as the last gasp of humanity, the Ship set out to preserve the species by seeding the universe with one billion colonists. Generations of crew, trained to be either flight or marines, have spent 5,000 years protecting the Ship and its civilian cargo from the constant threat of alien violence. Fifteen-year-old Zax has always had trouble fitting in with the other cadets, but he's finally on the cusp of attaining his dream and gaining entrance to the Pilot Academy.

The immortals are 10 individuals born in antiquity from various cultures. Immune to disease, able to heal themselves from injuries, they will never die of old age - although they can fall victim to catastrophic wounds. They have walked among mortals for millennia, traveling across the world, trying to understand their special gifts while searching for one another in the hope of finding some meaning in a life that may go on forever.

College student, ex-marine, and martial artist Malcolm Lockridge is in prison awaiting his trial for murder when he receives an unexpected visit from an extraordinarily beautiful woman named Storm. Claiming to be a representative of the Wardens, a political faction from 2,000 years in the future, Storm offers the astonished young man a proposition: freedom in return for his assistance in recovering an unspecified lost treasure. But it is not long before Malcolm realizes that, in truth, he's been recruited as a soldier in the Wardens' ongoing war against their rivals, the Rangers.
