Hard Science Fiction Space

When Unit Four - a biological soft robot built and stored high above the Jovian atmosphere - is activated for the first time, it’s in crisis mode. Aliens are attacking the Helium-3 mine it was created to oversee, and now its sole purpose is to defend Earth’s largest energy resource from the invaders in ship-to-ship combat. But something’s wrong. Unit Four doesn’t feel quite right. There are files in its databanks it can’t account for, unusual chemical combinations roaring through its pipes, and the primers it possesses on the aliens are suspiciously sparse.

While recovering from the physical and emotional wounds he sustained in Challenger's Hope, Nick Seafort is named as the liaison between the wealthy planters of Hope Nation and the United Nations Navy. The lurking, acid-spewing, fish-shaped aliens are a real threat, and everyone is on edge. When the fleet returns to Earth, dissent grows among the people of Hope Nation, who feel abandoned by the military and left at the mercy of the alien horde.

The gates have opened the way to a thousand new worlds, and the rush to colonise has begun. Settlers looking for a new life stream out from humanity's home planets. Illus, the first human colony on this vast new frontier, is being born in blood and fire. Independent settlers stand against the overwhelming power of a corporate colony ship with only their determination, courage, and the skills learned in the long wars of home.

The first US / UN invasion of the renegade lunar colony of Aristillus has failed - but the powers-that-be in Washington and elsewhere can't give up. Their political careers - and an escape from the economic decline of Earth under a command-and-control economy - depend on conquering the lunar expats. A second - and final - invasion is planned. The lunar settlers prepare to repel the onslaught, but what can a small population of 1 million do against the combined might of billions on Earth - especially now that the PKs have the secret of the antigravity drive?

Nick Morrison always wanted to be an astronaut. When a start-up company recruits him to build a lunar launch system at the moon’s south pole, Nick gladly leaves behind his troubled life on Earth—but Nick doesn’t know that the company is in financial and legal trouble. Deprived of support from Earth, the team on the moon must figure out how to survive on their own. Worse yet, there’s another base at the lunar south pole, run by a ruthless contractor who has big plans for the moon...and for Earth.

The ability for easy travel throughout the solar system has created nations and organizations on Earth who want to control Mars and the rich resources of the solar system. Mars has started its own military and is building a fleet to survive the brutal attacks from Earth. Mars has set up embassies on Earth and is facing spies and saboteurs intent on disrupting a content populace that is growing rapidly. Lux has developed new weapons, and Prissy joins the colony military.

The Federation's military command is desperate, and with their fleet still in tatters, they make a last-ditch effort to free the planet: They pull Captain Jackson Wolfe out of retirement and put him in command of a ship they hope can get past the defending armada and provide support to the beleaguered Marines and civilians fighting on the surface of the contested world. There is no reasoning with this enemy. If the Terran Federation wants their planet back, they will have to pay the price.

Stranded on the moon after a global economic crash, Nick Morrison and his friends must take decisive action to secure their supply chain before they starve to death. The capture of a space station wins them some breathing room. But the powers that be on Earth cannot tolerate an independent, thriving lunar colony. Amidst a high-stakes arms race, Nick and his friends struggle to hold off the entire might of Earth. At the same time, Nick must also fight his old nemesis, Joe Massad, for control of the lunar base.

Fifty years ago, Mira, humanity's last hope to find new resources, exited the solar system bound for Proxima Centauri B. Seven years into her mission, all transmissions ceased without warning. Mira and her crew were presumed lost. Humanity, unified during her construction, splintered into insurgency and rebellion.

The struggle for survival sharpens as resources dwindle, technology fails, and the grim reality of life on Donovan unfolds. Supervisor Kalico Aguila has bet everything on a fragile settlement far south of Port Authority. There, she has carved a farm and mine out of wilderness. But Donovan is closing in. When conditions couldn't get worse, a murderous peril descends out of Donovan's sky - one that will leave Kalico bleeding and shattered.

Priscilla “Hutch” Hutchins discovers an interstellar message from a highly advanced race that could be her last chance for a mission before the program is shut down for good. Hutch has been the academy’s best pilot for decades. She’s had numerous first contact encounters and even became a minor celebrity. But world politics have shifted from exploration to a growing fear that the program will run into an extraterrestrial race more advanced than humanity and war.

Faced with determining the fate of the galaxy, Golan Trevize hesitantly chose to hand over the rule of the galaxy to planet Gaia. Two mysteries now remain: who has erased the records of Earth – and why? Determined to ensure his choice was right, Golan sets off with Janov Pelorat and Bliss, to answer these questions once and for all. But nothing could prepare them for the secrets which await them on Earth. Secrets which predate history as they know it, and will change its significance forever.

They were sent to build a utopia, but all they found on Mars was death. Frank Kitteridge has been abandoned. But XO, the greedy - and ultimately murderous - corporate architects of humanity's first Mars base made a costly mistake when they left him there: They left him alive. Using his skills and his wits, he's going to find a way back home even if it kills him. Little does he know that Mars isn't completely empty. Just over the mountain, there's another XO base where things are going terribly, catastrophically wrong.

Everyone knows Nick Seafort as The Fisherman - the hero who stopped the merciless, fishlike aliens when they attacked Earth.

The legendary battle-carrier UFS Phoenix is on the run in Outer Neutral Space. Lieutenant Commander Erik Debogande and Major Trace Thakur are determined to use neutral territory to broker a peace between humanity's warring factions, away from Fleet's strong arm. But as machinations in Fleet Command send a legendary warrior from Trace's past on a sworn path to kill her, there arises in the territory of an insectoid foe an ancient enemy from the nightmares of Spiral history, bent on Phoenix's destruction….

The Ixa smashed the galaxy to bits before they were defeated. Captain Husher has sounded the alarm in the decades since: the Ixa’s creators will return to finish the job. But unlike Husher, the galactic government didn't battle the Ixa, and the politicians have convinced themselves that maintaining peace means limiting the ability to wage war.

The Tantalus 13 survey expedition went off the rails as soon as Mary Ketch and the crew of the Diamelen learned that the thing beneath their feet wasn’t a planet. An impossibly vast and ancient artificial structure lies below, hidden from the universe under a façade of cratered stone. SCARAB arrived on Tantalus 13 two years ago. An artificially intelligent, self-constructing factory, it was supposed to aid the crew in their mission, to meet their every need.

Now, as Turek readies an all-out attack on the Nexus system - a key conquest that could seal the rest of the galaxy's doom - Ky must rally to the challenge, draw upon every last reserve of her strategic skills, and reach deep if she is to tear from the ashes of tragedy her most decisive victory.

The Year is 2040. The Marines have landed on Mars to guard the unearthed secrets of an ancient and dangerous alien race: Ourselves.
