Silent Cities: 10 Sci-Fi Novels Set in Abandoned Megastructures

The war raged across the galaxy. Billions had died, billions more were doomed. Moons, planets, the very stars themselves, faced destruction, cold-blooded, brutal, and worse, random. The Idirans fought for their Faith; the Culture for its moral right to exist. Principles were at stake. There could be no surrender.

Within the cosmic conflict, an individual crusade. Deep within a fabled labyrinth on a barren world, a Planet of the Dead proscribed to mortals, lay a fugitive Mind. Both the Culture and the Idirans sought it. It was the fate of Horza, the Changer, and his motley crew of unpredictable mercenaries, human and machine, actually to find it, and with it their own destruction.

The year is 2380. The Intersolar Commonwealth, a sphere of stars some four hundred light-years in diameter, contains more than six hundred worlds, interconnected by a web of transport “tunnels” known as wormholes. At the farthest edge of the Commonwealth, astronomer Dudley Bose observes the impossible: Over one thousand light-years away, a star… vanishes. It does not go supernova. It does not collapse into a black hole. It simply disappears. Since the location is too distant to reach by wormhole, a faster-than-light starship, the Second Chance, is dispatched to learn what has occurred and whether it represents a threat. In command is Wilson Kime, a five-time rejuvenated ex-NASA pilot whose glory days are centuries behind him.

Opposed to the mission are the Guardians of Selfhood, a cult that believes the human race is being manipulated by an alien entity they call the Starflyer. Bradley Johansson, leader of the Guardians, warns of sabotage, fearing the Starflyer means to use the starship’s mission for its own ends.

Pursued by a Commonwealth special agent convinced the Guardians are crazy but dangerous, Johansson flees. But the danger is not averted. Aboard the Second Chance, Kime wonders if his crew has been infiltrated. Soon enough, he will have other worries. A thousand light-years away, something truly incredible is waiting: a deadly discovery whose unleashing will threaten to destroy the Commonwealth… and humanity itself. Could it be that Johansson was right?

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 an 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. 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.

The Twin Novae battle had been one of the last of the Idiran war, one of the most horrific. Desperate to avert defeat, the Idirans had induced not one but two suns to explode, snuffing out worlds & biospheres teeming with sentient life. They were attacks of incredible proportion – gigadeathcrimes. But the war ended and life went on. Now, 800 years later, light from the 1st explosion is about to reach the Masaq’ Orbital, home to the Culture’s most adventurous & decadent souls. There it will fall upon Masaq’s 50 billion inhabitants, gathered to commemorate the deaths of the innocent & to reflect, if only for a moment, on what some call the Culture’s own complicity in the terrible event.

Also journeying to Masaq’ is Major Quilan, an emissary from the war-ravaged world of Chel. In the aftermath of the conflict that split his world apart, most believe he has come to Masaq’ to bring home Chel’s most brilliant star & self-exiled dissident, the honored Composer Ziller. Ziller claims he will do anything to avoid a meeting with Quilan, who he suspects has come to murder him. But the Major’s true assignment will have far greater consequences than the death of a mere political dissident, as part of a conspiracy more ambitious than even he can know–a mission his superiors have buried so deeply in his mind that even he can’t remember it.

The Ship has traveled the universe for longer than any of the near-immortal crew can recall, its true purpose and origins unknown. It is larger than many planets, housing thousands of alien races and just as many secrets.

Now one of those secrets has been at the center of the Ship is . . . a planet. Marrow. But when a team of the Ship’s best and brightest are sent down to investigate, will they return with the origins of the Ship–or will they bring doom to everyone on board?

Robert Reed, whose fantastic stories have been filling all the major SF magazines for the past several years, spins a captivating tale of adventure and wonder on an incredible scale in this novel based on his acclaimed novella.

In a world renowned within a galaxy full of wonders, a crime within a war. For one brother it means a desperate flight, and a search for the one – maybe two – people who could clear his name. For his brother it means a life lived under constant threat of treachery and murder. And for their sister, it means returning to a place she’d thought abandoned forever.

Only the sister is not what she once was; Djan Seriy Anaplian has become an agent of the Culture’s Special Circumstances section, charged with high-level interference in civilisations throughout the greater galaxy.

Concealing her new identity – and her particular set of abilities – might be a dangerous strategy. In the world to which Anaplian returns, nothing is quite as it seems; and determining the appropriate level of interference in someone else’s war is never a simple matter.

In this first collaboration by science fiction masters Larry Niven (Ringworld) and Gregory Benford (Timescape), the limits of wonder are redrawn once again as a human expedition to another star system is jeopardized by an encounter with an astonishingly immense artifact in interstellar space: a bowl-shaped structure half-englobing a star, with a habitable area equivalent to many millions of Earths…and it’s on a direct path heading for the same system as the human ship.

A landing party is sent to investigate the Bowl, but when the explorers are separated–one group captured by the gigantic structure’s alien inhabitants, the other pursued across its strange and dangerous landscape–the mystery of the Bowl’s origins and purpose propel the human voyagers toward discoveries that will transform their understanding of their place in the universe.

2057. Bella Lind and the crew of her nuclear-powered ship, the Rockhopper, push ice. They mine comets. But when Janus, one of Saturn’s ice moons, inexplicably leaves its natural orbit and heads out of the solar system at high speed, Bella is ordered to shadow it for the few vital days before it falls forever out of reach.

In accepting this mission she sets her ship and her crew on a collision course with destiny—for Janus has many surprises in store, and not all of them are welcome…

A race for survival among the stars… Humanity’s last survivors escaped earth’s ruins to find a new home. But when they find it, can their desperation overcome its dangers?

WHO WILL INHERIT THIS NEW EARTH?

The last remnants of the human race left a dying Earth, desperate to find a new home among the stars. Following in the footsteps of their ancestors, they discover the greatest treasure of the past age—a world terraformed and prepared for human life.

But all is not right in this new Eden. In the long years since the planet was abandoned, the work of its architects has borne disastrous fruit. The planet is not waiting for them, pristine and unoccupied. New masters have turned it from a refuge into mankind’s worst nightmare.

Now two civilizations are on a collision course, both testing the boundaries of what they will do to survive. As the fate of humanity hangs in the balance, who are the true heirs of this new Earth?

The artefact is a circular ribbon of matter six hundred million miles long and ninety million miles in radius. Pierson’s puppeteers, the aliens who discovered it, are understandably wary of encountering the builders of such an immense structure and have assembled a team of two humans, a mad puppeteer and a kzin, a huge cat-like alien, to explore it. But a crash landing on the vast edifice forces the crew on a desperate and dangerous trek across the Ringworld.
