The Engines of God


Jack McDevitt - 1994
    Now, as faster-than-light drive opens the stars to exploration, humans are finding other relics of the race they call the Monument-Makers - each different, and each heartbreakingly beautiful. But except for a set of footprints on Jupiter's moon Iapetus, there is no trace of the enigmatic race that has left them behind. Then a team of scientists working on a dead world discover an ominous new image of the Monument-Makers. Somehow it all fits with other lost civilizations, and possibly with Earth's own future. And distant past. But Earth itself is on the brink of ecological disaster - there is no time to search for answers. Even to a question that may hold the key to survival for the entire human race...

Eon


Greg Bear - 1985
    NASA, NATO, and the UN sent explorers to the asteroid's surface...and discovered marvels and mysteries to drive researchers mad.For the Stone was from space--but perhaps not our space; it came from the future-but perhaps not our future; and within the hollowed asteroid was Thistledown. The remains of a vanished civilization. A human--English, Russian, and Chinese-speaking--civilization. Seven vast chambers containing forests, lakes, rivers, hanging cities...And museums describing the Death; the catastrophic war that was about to occur; the horror and the long winter that would follow.

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.

Valor's Choice


Tanya Huff - 2000
    They must act as soldier/protectors of the far more civilized races who have long since turned away from war... — Staff Sergeant Torin Kerr was a battle-hardened professional. So when she and those in her platoon who'd survived the last deadly encounter with the Others were yanked from a well-deserved leave for what was supposed to be "easy" duty as the honor guard for a diplomatic mission to the non-Confederation world of the Silsviss, she was ready for anything.At first it seemed that all she'd have to contend with was bored troops getting into mischief, and breaking in the new Second Lieutenant who had been given command of her men.Sure, there'd been rumors of the Others - the sworn enemies of the Confederation - being spotted in this sector of space. But there were always rumors. The key thing was to recruit the Silsviss into the Confederation before the Others either attacked or claimed this lizardlike race of warriors for their own side. And everything seemed to be going perfectly. Maybe too perfectly...

Remnant Population

But while her fellow colonists grudgingly anticipate a difficult readjustment on some distant world, Ofelia savors the promise of a golden opportunity. Not starting over in the hurly-burly of a new community... but closing out her life in blissful solitude, in the place she has no intention of leaving.

But when a reconnaissance ship returns to her idyllic domain, and its crew is mysteriously slaughtered, Ofelia realizes she is not the sole inhabitant of her paradise after all. And, when the inevitable time of first contact finally arrives, she will find her life changed yet again–in ways she could never have imagined...

Noumenon


Marina J. Lostetter - 2017
    But one uncertainty remains: Where do we go? Astrophysicist Reggie Straifer has an idea. He’s discovered an anomalous star that appears to defy the laws of physics, and proposes the creation of a deep-space mission to find out whether the star is a weird natural phenomenon, or something manufactured.The journey will take eons. In order to maintain the genetic talent of the original crew, humankind’s greatest ambition—to explore the furthest reaches of the galaxy—is undertaken by clones. But a clone is not a perfect copy, and each new generation has its own quirks, desires, and neuroses. As the centuries fly by, the society living aboard the nine ships (designated “Convoy Seven”) changes and evolves, but their mission remains the same: to reach Reggie’s mysterious star and explore its origins—and implications.A mosaic novel of discovery, Noumenon—in a series of vignettes—examines the dedication, adventure, growth, and fear of having your entire world consist of nine ships in the vacuum of space. The men and women, and even the AI, must learn to work and live together in harmony, as their original DNA is continuously replicated and they are born again and again into a thousand new lives. With the stars their home and the unknown their destination, they are on a voyage of many lifetimes—an odyssey to understand what lies beyond the limits of human knowledge and imagination.
