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.

Arthur C Clarke is without question the world's best-known and most celebrated science-fiction writer. His career, spanning more than 60 years, is one of unequalled success. Clarke has always been celebrated for his clear prophetic vision, which is fully on display in this audiobook, but there are also many stories that show his imagination in full flight, to the distant future and to far-flung star systems.

In the 22nd century visionary scientist Vannevar Morgan conceives the most grandiose engineering project of all time, and one which will revolutionise the future of humankind in space: a Space Elevator, 36,000 kilometres high, anchored to an equatorial island in the Indian Ocean.

Men had built cities before, but never such a city as Diaspar; for millennia its protective dome shut out the creeping decay and danger of the world outside. Once, it ruled the stars. But then, as legend had it, the Invaders came, driving humanity into this last refuge. It takes one man, a Unique, to smash the legend and discover the true nature of the Invaders.

It has been 40 years since the publication of this classic science-fiction novel that changed the way we look at the stars and ourselves.

When the silent spacecraft arrived and took the light from the world, no one knew what to expect. When the Overlords finally showed themselves it was a shock but one that humankind could now cope with, and an era of peace, prosperity and endless leisure began.

Ryland Grace is the sole survivor on a desperate, last-chance mission - and if he fails, humanity and the Earth itself will perish. Except that right now, he doesn't know that. He can't even remember his own name, let alone the nature of his assignment or how to complete it. All he knows is that he's been asleep for a very, very long time. And he's just been awakened to find himself millions of miles from home, with nothing but two corpses for company.

Mars. The red planet. A new frontier for humanity: a civilisation where humans can live in peace, lord and master of all they survey. But this isn't Space City from those old science-fiction books. It's more like Hell City, built into and from a huge crater. There's a big silk canopy over it, feeding out atmosphere as we generate it, little by little, because we can't breathe the air here. I guess it's a perfect place to live, if you want to live on Mars. At some point I must have wanted to live on Mars, because here I am.

The mysterious object ripped across the landscape, tearing a spiral path of devastation along its route. After it crashed, military intelligence took it to Hatch Air Force Base and began a series of top-secret tests, trying to uncover the workings of the craft. When the ship was opened, they found an extraordinarily instrumented capsule - and the body of a humanoid pilot.

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.

From a childish fear of the dark in "The End of the Party" to the chilling conclusion of the "Destructors" and the all-consuming selfishness of "May We Borrow Your Husband", this collection opens with three of Greene's most disturbing stories. Things take a surreal turn in "Under the Garden" before finally blossoming for a moment in "Two Gentle People", then there's a detective story and a brush with Greene's sardonic wit to finish.
