Consider Phlebas


Iain M. Banks - 1987
    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.

Mission of Gravity


Hal Clement - 1954
    The title is a play on words, one meaning "the force which pulls" & the other being "extremely serious or important". It was serialized in Astounding Science Fiction, 4–7/53. Its 1st cloth publication was in '54. It was 1st published in paper in '58. Along with the novel itself, many editions (& most recent editions) of the book also include Whirligig World, an essay on creating the planet Mesklin that was published in the 6/53 Astounding. He published two sequels, a '70 novel called Star Light & a '73 short story called Lecture Demonstration. Mission of Gravity was nominated for a Retro Hugo Award for '54.For a profit & adventure Barlennan would sail thousands of miles across uncharted waters, into regions where gravity played strange tricks. He'd dare the perils of strange tribes & stranger creatures--even dicker with those aliens from beyond the skies, though the concept of another world was unknown to the inhabitants of the planet of Mesklin. But in spite of the incredible technology of the strangers & without regard for their enormous size, Barlennan had the notion of turning the deal to an unsuspected advantage for himself--a considerable enterprise for a being very much resembling a 15" caterpillar!

Pandora's Star


Peter F. Hamilton - 2004
    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?

His battle to realize his dream results in two momentous discoveries anti-gravity and the secret of immortality. In A Life for the Stars, it is centuries later and anti-gravity generations have enabled whole cities to lift off the surface of the earth to become galactic wanderers. In Earthman, Come Home, the nomadic cities revert to barbarism and marauding rogue cities begin to pose a threat to all civilized worlds. In the final novel, The Triumph of Time, history repeats itself as the cities once again journey back in to space making a terrifying discovery which could destroy the entire Universe. A serious and haunting vision of our world and its limits, Cities in Flight marks the return to print of one of science fiction's most inimitable writers.A Selection of the Science Fiction Book Club
