Time is running out for the passengers and crew of the tourist-cruiser “Selene”, incarcerated in a sea of choking lunar dust. On the surface, her rescuers find their resources stretched to the limit by the pitiless and unpredictable conditions of a totally alien environment.

Apenas algumas ilhas espalhadas num planeta selvagem oceânico, Thalassa era um verdadeiro paraíso. Feliz e tranquilo, o povo de Thassala deleitava-se em viver bem no seu belo e abastado mundo. Envolvdos pelos encantos e recursos do planeta, aqueles colonos não suspeitavam do colossal evento que repentinamente tomaria lugar sobre seus mares. O idílio de Thalassa seria rompido em breve com o aparecimento de Magalhães em sua órbita.Protegida por um escudo de gelo que a cercava, Magalhães tinha a aparência fascinante de um enorme cristal esverdeado e resplandecente. Por dentro do iceberg, artificial, Magalhães uma nave espacial de proporções gigantescas, transportava um milhão de refugiados da Terra em estado de hibernação. Eles eram os sobreviventes dos últimos e alucinados dias da civilização humana em seu planeta de origem.A chegada de Magalhães a Thalassa fatalmente abalaria a calma e segurança dos nativos: a astronave estaria só fazendo uma escala em sua jornada para uma estrela mais distante, como alegou a tripulação, ou a intenção era ficar e estabelecer os passageiros naquele cenário divino?

Nebula Best Novel winner (1974)Hugo Best Novel winner (1974)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 an interstellar spacecraft. Space explorers and planet-bound scientists alike prepare for mankind’s first encounter with alien intelligence. It will kindle their wildest dreams… and fan their darkest fears. For no one knows who the Ramans are or why they have come. And now the moment of rendezvous awaits—just behind a Raman airlock door.

Returned to the Earth of 2037 by the Firstborn, mysterious beings of almost limitless technological prowess, Bisesa Dutt is haunted by the memories of her five years spent on the strange alternate Earth called Mir, a jigsaw-puzzle world made up of lands and people cut out of different eras of Earth’s history. Why did the Firstborn create Mir? Why was Bisesa taken there and then brought back on the day after her original disappearance? Bisesa’s questions receive a chilling answer when scientists discover an anomaly in the sun’s core-an anomaly that has no natural cause is evidence of alien intervention over two thousand years before. Now plans set in motion millennia ago by inscrutable watchers light-years away are coming to fruition in a sunstorm designed to scour the Earth of all life in a bombardment of deadly radiation. Thus commences a furious race against a ticking solar time bomb. But even now, as apocalypse looms, cooperation is not easy for the peoples and nations of the Earth. Religious and political differences threaten to undermine every effort. And all the while, the Firstborn are watching …

Men had built cities before, but never such a city as Diaspar; for millennia its protective dome shutout the creeping decay and danger of the world outside. Once, it held powers that rules the stars. But then, as legend had it, the Invaders came, driving humanity into this last refuge. It takes one man, a Unique to break through Diaspar’s stifling inertia, to smash the legend and discover the true nature of the Invaders.

Two of science fiction’s most renowned writers join forces for a storytelling sensation. The historic collaboration between Frederik Pohl and his fellow founding father of the genre, Arthur C. Clarke, is both a momentous literary event and a fittingly grand farewell from the late, great visionary author of 2001: A Space Odyssey.The Last Theorem is a story of one man’s mathematical obsession, and a celebration of the human spirit and the scientific method. It is also a gripping intellectual thriller in which humanity, facing extermination from all-but-omnipotent aliens, the Grand Galactics, must overcome differences of politics and religion and come together… or perish.In 1637, the French mathematician Pierre de Fermat scrawled a note in the margin of a book about an enigmatic theorem: “I have discovered a truly marvelous proof of this proposition which this margin is too narrow to contain.” He also neglected to record his proof elsewhere. Thus began a search for the Holy Grail of mathematics—a search that didn’t end until 1994, when Andrew Wiles published a 150-page proof. But the proof was burdensome, overlong, and utilized mathematical techniques undreamed of in Fermat’s time, and so it left many critics unsatisfied—including young Ranjit Subramanian, a Sri Lankan with a special gift for mathematics and a passion for the famous “Last Theorem.”When Ranjit writes a three-page proof of the theorem that relies exclusively on knowledge available to Fermat, his achievement is hailed as a work of genius, bringing him fame and fortune. But it also brings him to the attention of the National Security Agency and a shadowy United Nations outfit called Pax per Fidem, or Peace Through Transparency, whose secretive workings belie its name. Suddenly Ranjit—together with his wife, Myra de Soyza, an expert in artificial intelligence, and their burgeoning family—finds himself swept up in world-shaking events, his genius for abstract mathematical thought put to uses that are both concrete and potentially deadly.Meanwhile, unbeknownst to anyone on Earth, an alien fleet is approaching the planet at a significant percentage of the speed of light. Their mission: to exterminate the dangerous species of primates known as homo sapiens.

BLAST OFF!"Between the first and last decades of the Twentieth Century lay a gulf greater than the wildest imagination could have conceived. It was the gulf between gunpowder and nuclear bomb, between messages tapped in morse code and global television from the sky, between Queen Victoria, Empress of India, and Kwame Chaka, Supreme President of the African Federation. But above all, it was the gulf between the first hundred-foot flight at Kitty Hawk , and the first billion mile mission to the moons of Jupiter. . . ."This was the beginning of the first version of 2001-the version that never was published. Now at last you can go that first great voyage . . . a trip far different than that of 2001 . . . an adventure in many ways even stranger and more fascinating . . . as you move through time and space toward the extraordinary revelation that awaits you in-THE LOST WORLDS OF 2001ARTHUR C.

Ever done anything for no particular reason at all? Ever feel as if you were arguing with yourself? Do you sometimes get the feeling that you're really two people who are at odds over the basic rights and wrongs of life?Probably you’re merely schizophrenic, and there's nothing to worry about except the prospect of life in a padded cell. But, on the other hand, perhaps. . . ,
