Hard Science Fiction Space

Nine hundred thousand years ago, something annihilated the Amarantin civilization just as it was on the verge of discovering space flight. Now one scientist, Dan Sylveste, will stop at nothing to solve the Amarantin riddle before ancient history repeats itself. With no other resources at his disposal, Sylveste forges a dangerous alliance with the cyborg crew of the starship Nostalgia for Infinity. But as he closes in on the secret, a killer closes in on him because the Amarantin were destroyed for a reason.

The shady crew of the White Raven run freight and salvage at the fringes of our solar system. They discover the wreck of a centuries-old exploration vessel floating light years away from its intended destination and revive its sole occupant, who wakes with news of First Alien Contact. When the crew break it to her that humanity has alien allies already, she reveals that these are very different extra-terrestrials and the gifts they bestowed on her could kill all humanity, or take it out to the most distant stars.

The Singularity. It is the era of the posthuman. Artificial intelligences have surpassed the limits of human intellect. Biotechnological beings have rendered people all but extinct. Molecular nanotechnology runs rampant, replicating and reprogramming at will. Contact with extraterrestrial life grows more imminent with each new day.

A troubled young woman is recruited by a race of ancient alien explorers to be their emissary to save the human race from extinction. The problem is that not everyone believes the world is doomed, and not everyone trusts the aliens' motives. Holly Burton will have to overcome opposition from world leaders, attacks by religious zealots, assassination attempts, intractable bureaucracies, and her own fears and doubts if she is to save the human race, not just from the coming apocalypse, but from itself.

A ship under siege. A world on the brink of civil war. A distraught people seeking a new beginning. A battle weary crew that can barely hold it together. Even a legend can use a little help from time to time. The crew of the Aurora, the Karuzari, and the Corinairans must find a way to work together, or else they may all perish.

In AD 2600, the human race is finally beginning to realize its full potential. Hundreds of colonized planets scattered across the galaxy host a multitude of prosperous and wildly diverse cultures. Genetic engineering has pushed evolution far beyond nature's boundaries, defeating disease and producing extraordinary spaceborn creatures. Huge fleets of sentient trader starships thrive on the wealth created by the industrialization of entire star systems, and throughout inhabited space the Confederation Navy keeps the peace.

High above the windswept plains of Kazakhstan, three astronauts on board a Russian Soyuz capsule begin their reentry. A strange shimmer in the atmosphere, a blinding flash of light, and the capsule vanishes in a blink as though it never existed. Daniel Rice is a government science investigator. Marie Kendrick is a NASA operations analyst. Together, they must track down the cause of the most bizarre event in the history of human spaceflight. They draw on scientific strengths as they plunge into the strange world of quantum physics.

First contact with a mysterious race of aliens reveals an unusual request; a family's pet dog comes to grips with the newly bestowed gift of human-like intelligence; a poet, in danger and alone on a distant world, makes unlikely allies; hundreds of years in the future, a famous hermit lives in the sea above the now-underwater Harvard University; former friends navigate unsteady peace between human refugees and the technologically superior race that saved them; in a future where human life can be infinitely extended through cybertronic rebirth, one woman declines immortality.

Tom Dreyfus is a Prefect, a law enforcement officer with the Panoply. His beat is the multifaceted utopian society of the Glitter Band, that vast swirl of space habitats orbiting the planet Yellowstone, the teeming hub of a human interstellar empire spanning many worlds. His current case: investigating a murderous attack against one of the habitats that left 900 people dead, a crime that appalls even a hardened cop like Dreyfus.

Late in the 26th century, the human race has advanced enough to accidentally trigger the Inhibitors---alien-killing machines designed to detect intelligent life and destroy it. The only hope for humanity lies in the recovery of a secret cache of doomsday weapons---and a renegade named Clavain who is determined to find them. But other factions want the weapons for their own purposes---and the weapons themselves have another agenda altogether.

The very far future: The galaxy is a drifting wreck of black holes, neutron stars, and chill white dwarfs. The age of star formation is long past. Yet there is life here, feeding off the energies of the stellar remnants, and there is mind, a tremendous galaxy-spanning intelligence each of whose thoughts lasts a hundred thousand years. And this mind cradles memories of a long-gone age when a more compact universe was full of light... The 27th century: Proxima Centauri, an undistinguished red dwarf star, is the nearest star to our sun. How would it be to live on such a world?

A world recovering from a devastating plague. A brutal enemy threatening invasion. A young man seeking to escape the shadow of his father. A ship manned by a crew of fresh academy graduates. A top-secret experimental propulsion system. A questionable alliance with a mysterious green-eyed woman. What destiny has in store for the crew of the UES Aurora is far greater than any of them could ever imagine. And this is only the beginning....

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.

In 2118 the first daring mission to another star, Tau Ceti - 12 light-years away - is launched. Tom Hites and Harry Cosgrove command the starship Endeavour on an epic journey to solve the Fermi paradox. From the first nearly disastrous steps on a distant world, their quest takes them further than they ever imagined.

In 2088, humankind is at last ready to explore beyond Earth's solar system. 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.

Autistic scientist Yasira Shien has developed a radical new energy drive that could change the future of humanity. But when she activates it, reality warps, destroying the space station and everyone aboard. The AI gods who rule the galaxy declare her work heretical, and Yasira is abducted by their agents. Instead of simply executing her, they offer mercy - if she'll help them hunt down a bigger target: her own mysterious, vanished mentor. With her homeworld's fate in the balance, Yasira must choose who to trust: the gods and their ruthless post-human angels, or a rebel scientist....
