This science fiction novel describes the epic voyage of the spacecraft Leonora Christine. From practically the very first minute, Tau Zero sets scientific realities in dramatic tension with the very real emotional and psychological states of the travelers, exploring the effect of time contraction due to traveling at near-light speed on the human psyche. This tension is a dynamic that Anderson explores with great success over the course of the novel, as 50 crewmembers settle in for the long journey together.

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.

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.

Thor has broken the sword Tyrfing so that it cannot strike at the roots of Yggdrasil, the tree that binds together earth, heaven, and hell. But now the mighty sword is needed again to save the elves in their war against the trolls, and only Skafloc, a human child kidnapped and raised by the elves, can hope to persuade Bölverk the ice-giant to make Tyrfing whole again. But Skafloc must also confront his shadow self, Valgard the changeling, who has taken his place in the world of men.

As Sir Roger Baron de Tourneville is gathering an army to join King Edward III in the war against France, a most astonishing event occurs: a huge silver ship descends through the sky and lands in a pasture beside the little village of Ansby in North East Lincolnshire. The Wersgorix, whose scouting ship it is, are quite expert at taking conquering planets, and having determined from orbit that this one is suitable, they initiate standard procedure. Their ship carries guided missiles and nuclear weaponry—but they have long since lost the art of hand-to-hand fighting.

The gathering forces of the Dark Powers threaten the world of man. The legions of Faery, aided by trolls, demons, and the Wild Hunt itself, are poised to overthrow the Realms of Light. Holger Carlsen, a bemused and puzzled twentieth-century man mysteriously snatched out of time, finds himself the key figure in the conflict. Arrayed against him are the dragons, giants, and elfin warriors of the armies of Chaos and the beautiful sorceress Morgan le Fay.

Terre. XXIIIe siècle. Cinquante astronautes. Vingt-cinq femmes, vingt-cinq hommes, parmi les meilleurs dans leurs domaines : astrophysiciens, mathématiciens, biologistes, astronavigateurs... partent pour un impressionnant voyage : rejoindre l'étoile Beta Virginis à trente-deux années-lumière de la Terre. Ils disposent pour ce faire du plus stupéfiant des vaisseaux, le Leonora Christina, dernier né de sa génération, un navire capable de puiser son énergie au cœur même de l'espace et d'évoluer à des vitesses relativistes.

No longer a brash, young ensign, Captain Dominic Flandry has risen in rank but now appreciates fully that the Terran empire is old and tired, wanting to be left in peace. But the enemies it has made and the competing empire of Merseia will give it no peace. Too evenly matched for open warfare not to destroy them both, the opponents engage in subtle thrust and counter-thrust, feint and counter-feint, with Flandry in the thick of it.

Forget minor hazards like nuclear bombs. The discovery of time travel means that everything we know, anyone we know, might not only vanish, but never even have existed. Against that possibility stand the men and women of the Time Patrol, dedicated to preserving the history they know and protecting the future from fanatics, terrorists, and would-be dictators who would remold the shape of reality to suit their own purposes.

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.

This volume contains a variety of imaginative stories from both famous and not-so-famous science fiction writers.

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!)

On a far-future Earth, a linked system of artificial intelligences called the cybercosm runs the planet and the universe far more efficiently than any flesh and blood ruler ever could, in essence rendering the human race obsolete. On the Earth's moon, genetically engineered Lunarians carrying the DNA of Dagney Beynac - a descendant of the legendary Anton Guthrie, founder of the powerful and visionary Fireball Enterprises - struggle to preserve their lives, their freedom, and their satellite's resources in the face of threats posed by encroaching humans and controlling machines.

Sir Dominic Flandry is now an admiral, but takes little joy in his new rank. He sees the rot in the Terran Empire on every hand and knows that the Long Night will inevitably fall upon the galaxy. His consolation is that measures he has taken while doing what he can to postpone the empire's final collapse may shorten the coming galactic dark age and hasten the rise of a new interstellar civilization. In the meantime, he'll enjoy the comforts of a decadent civilization - and he'll always be ready for one more battle against the empire's enemies.

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.

The virtual persona of a long-dead visionary entrepreneur threatens to incite a revolution from space that could topple Earth's powerful and repressive religious-technological dictatorship in this ingenious science-fiction classic.

From Nebula Award winner Gregory Benford comes this ambitious hard SF anthology that collects five original novellas. Each one takes the very long view - all are set at least ten thousand years in the future. The authors take a rigorously scientific view of such grand panoramas, confronting the largest issues of cosmology, astronomy, evolution, and biology.

The way we feel about another person or about objects is often bound up in associations that have no direct connection with the person or object, at all. Often, what we call a "change of heart" comes about sheerly from a change in the many associations which make up our present viewpoint. Now, suppose that these associations could be altered artificially, at the option of the person who was in charge of the process.
