Thousands of years in the future, humanity is no longer alone in a universe where a mind's potential is determined by its location in space, from superintelligent entities in the Transcend, to the limited minds of the Unthinking Depths, where only simple creatures, and technology, can function. Nobody knows what strange force partitioned space into these "regions of thought," but when the warring Straumli realm use an ancient Transcendent artifact as a weapon, they unwittingly unleash an awesome power that destroys thousands of worlds and enslaves all natural and artificial intelligence. Fleeing this galactic threat, Ravna crash lands on a strange world with a ship-hold full of cryogenically frozen children, the only survivors from a destroyed space-lab. They are taken captive by the Tines, an alien race with a harsh medieval culture, and used as pawns in a ruthless power struggle.

Two months since the stars fell... Two months since sixty-five thousand alien objects clenched around the Earth like a luminous fist, screaming to the heavens as the atmosphere burned them to ash. Two months since that moment of brief, bright surveillance by agents unknown. Two months of silence while a world holds its breath. Now some half-derelict space probe, sparking fitfully past Neptune's orbit, hears a whisper from the edge of the solar system: a faint signal sweeping the cosmos like a lighthouse beam. Whatever's out there isn't talking to us. It's talking to some distant star, perhaps. Or perhaps to something closer, something en route. So who do you send to force introductions on an intelligence with motives unknown, maybe unknowable? Who do you send to meet the alien when the alien doesn't want to meet? You send a linguist with multiple personalities, her brain surgically partitioned into separate, sentient processing cores. You send a biologist so radically interfaced with machinery that he sees X-rays and tastes ultrasound, so compromised by grafts and splices that he no longer feels his own flesh. You send a pacifist warrior in the faint hope she won't be needed, and a fainter hope that she'll do any good if she is needed. You send a monster to command them all, an extinct hominid predator once called "vampire," recalled from the grave with the voodoo of recombinant genetics and the blood of sociopaths. And you send a synthesist—an informational topologist with half his mind gone—as an interface between here and there, a conduit through which the Dead Center might hope to understand the Bleeding Edge. You send them all to the edge of interstellar space, praying you can trust such freaks and retrofits with the fate of a world. You fear they may be more alien than the thing they've been sent to find. But you'd give anything for that to be true, if you only knew what was waiting for them....

Rendezvous with Rama

Written in 1973, a massive 50 kilometre long alien cylinder begins to pass through the solar system provoking a hurried effort to intercept it. The closest available ship rushes to rendezvous so as to have a quick study before it gets too close to the sun. Able to enter via an airlock on one end of the ship, the crew explores the huge world found inside, a world full of wonder and mystery. As usual, the science is spot on. This is the best novel of Clarke's since 2001 and Childhood's End and is a truly grand adventure full of puzzles and ideas that lead you asking more questions than are answered. Enough questions in fact to lead to numerous inferior sequels, but enough answers to leave you satisfied. Don't pass up this gem of hard science fiction.

From inside cover Tor First Edition March 1999: Thirty thousand years before the events of A Fire upon the Deep, Pham Nuwen is living in anonymity among the Qeng Ho interstellar trading fleet. In high orbit above the planet Arachna, they wait for the awakening of its dormant population, the Spiders, who have burrowed deep into the planet, awaiting the relighting of the On/Off star their planet orbits. For when light returns, Arachna will at long last explode into a Golden Age of technology and commerce. But the slumbering Spiders' vulnerability has attracted another lurking presence -- the Emergents, a band of traders whose plans for Arachna are more sinister than anything the Qeng Ho could envision. Reluctant to share their spoils with the Qeng Ho, the Emergents unleash an attack unlike any seen in the Qeng Ho's millennia-long history of exploration, reducing their fleet to serfdom... and then to something worse. Reaching into memories so old and painful he can barely recall them, Pham gathers the other "survivors" about him and makes a final attempt to be worthy of a reputation as ancient and storied as the history of the Qeng Ho itself. But time is running out, for soon the Emergents' assault will strip Arachna bare. As Pham's underground resistance cell struggles against its torturers in space, a wondrously gifted clan of Spiders on the planet below fights another battle - to advance their technology quickly enough to defeat their terrestrial foes, and to somehow overcome the invisible enemy lurking above.
