Deadly radiation from a passing comet is about to destroy life on Earth. In desperation, the US government constructs a series of underground shelters to protect as many people as possible. They are expected to be underground for 20 years before returning back to the surface. But can they survive their time within the confines of the underground shelter? And what will they find when they finally emerge?

Technology has developed to the point where a person can be placed in a sleep state: a cross between suspended animation and a drug-induced coma. Just as the trial of the new technology is being completed, an unusual comet is discovered approaching Earth, bringing with it radiation that will wipe out all life on the planet.

Ian Stevens, director of the Deep Space Research Institute, isn’t interested in conducting research just for the sake of research. While the rest of the world - including the US Government - thinks that’s the DSRI’s sole mission, Stevens is actually interested in more - he wants manned space travel and the colonization of the moon. With NASA defunct, few scientific probes are being launched, and no one even talks about human spaceflight anymore. Stevens is out to change that.

A secret buried in the Antarctic. A puzzle unsolved for thousands of years. And a Brooklyn-born master gunnery sergeant who's royally pissed that he has to babysit the researchers sent to figure it all out. But when Patrick "Wic" Finnegan finally sees what the team has uncovered, he can't believe his eyes, nor is he prepared for the violence to come. Soon, the portal opens and unleashes a storm of unbridled fury upon humanity.

Lauren didn’t ask to be a hero. But one night during the graveyard shift at Jodrell Bank, she captured an astonishing fast radio burst from an alien race. And just like that, the fate of the world was thrust into her hands. Now she’s put everything on the line to blow open the conspiracy of silence surrounding UFOs. She's on the run from MI5 and a secret organization determined to stop her. After a year of dead ends and a heart-breaking personal tragedy, she’s on the verge of being forced to abandon her personal crusade.

Two hundred thousand feet up, things go horribly wrong. An experimental low-orbit spaceplane breaks up on reentry, falling to earth over a trail hundreds of miles long. And in its wake is the beginning of the most important mission in the history of spaceflight.

Abner Fortis joined the International Space Marine Corps for two reasons: to escape a life of drudgery building biodomes for his father’s company and to pay off several billion credits in student loans, which the ISMC promised to do. Every Space Marine starts out as a cherry, though, and Abner is no different. When he makes his first combat drop, or cherry drop, he’s a know-nothing second lieutenant added to the mission roster as an afterthought.

The starship Earthling, filled with thousands of hibernating colonists en route to a new world at Tau Ceti, is stranded beyond the solar system when the ship's three organic mental cores - disembodied human brains that control the vessel's functions - go insane. The emergency skeleton crew sees only one chance for survival: build an artificial consciousness in the Earthling's primary computer that can guide them to their destination - and hope it doesn't destroy the human race.

Late in the 21st century, Earth receives what looks like an urgent plea for help from planet Proxima Centauri b in the closest star system to the Sun.

It has been 40 years since the publication of this classic science-fiction novel that changed the way we look at the stars and ourselves. From the savannas of Africa at the dawn of mankind to the rings of Saturn as man adventures to the outer rim of our solar system, 2001: A Space Odyssey is a journey unlike any other.

When Dr. Jim Parsons awakens after a car accident, he finds himself in a future populated almost entirely by the young. But for the young to keep running the world, death is fetishized, and those who survive to old age are put down. In such a world, Parsons - with his innate desire to save lives - is a criminal and an outcast. For one revolutionary group, however, he may be just the savior they need to heal and revive their cryogenically frozen leader.

Five years ago Corin Cadence's brother entered the Serpent Spire - a colossal tower with ever-shifting rooms, traps, and monsters. Those who survive the spire's trials return home with an attunement: a mark granting the bearer magical powers. According to legend, those few who reach the top of the tower will be granted a boon by the spire's goddess. He never returned. Now it's Corin's turn. He's headed to the top floor, on a mission to meet the goddess.

Merritt Alder is done with Earth. The planet is polluted and overpopulated, and its people are hungry. Earth's first colony, Galena, is a pioneer world 10,000 light years away. It has clean air, unpolluted water, and continents of arable land. Anyone can start a new life…if they can get there. For Merritt, the journey is only the beginning. Obstacles arise every step of the way, forcing compromise and sacrifice. And not everyone on his ship is pure of heart. The bonds he forges on the journey will be the key to surviving on another world—a world anyone has yet to fully explore.

A formidable alien armada stands on the brink of vanquishing the cosmos, their gaze set firmly on every inhabited world. The last line of defense?

Kalian Gaines has a secret; he just doesn't know it yet. He looks like us, he lives like us...but he is not one of us. Kalian knows nothing outside of his mundane life teaching history on 30th-century Earth, until a day like any other triggers a series of events that will tie his fate to that of humanity. A human handprint, embedded into a rock with alien script, is discovered on a moon that mankind has never set foot on. This discovery holds a secret, which will sweep Kalian into the heart of a conspiracy that has corrupted the galaxy for 200,000 years.

They tried to destroy our planets. Our way of life. They tried to send us into extinction. But we, the Coalition, fought them and won. That was a decade ago. They’re known as the Host: a cabal of aliens seeking to dominate our sector of space. And they’re back - with help from a powerful new enemy. We’re outnumbered and unprepared. But there is hope. An ancient race of long-dead but technologically advanced aliens called the Navigators have a ship called the Blackstar that could potentially turn the tide. That is if I, Kai Locke, a humble ship racer, can find it and learn how to harness its power in time.

Convicted criminal James Griffin-Mars is no one's hero. In his time, Earth is a toxic, abandoned world, and humans have fled into the outer solar system to survive, eking out a fragile, doomed existence among the other planets and their moons. Those responsible for delaying humanity's demise believe time travel holds the key, and they have identified James, troubled though he is, as one of a select and expendable few ideally suited for the most dangerous job in history.

After decades hunting wanted offworlders throughout the solar system, Corporate Bounty Hunter Malcolm Graves doesn't bother asking questions. So long as the pay is right, he's the man for the job.

A young man more interested in statistics than instinct. Their assignment: Track down a suspected group of extremists from Titan who will go to any length to free their moon from the grip of Earth's corporations.

Evan Gabriel wasn't always a feared and respected North American Federation Navy Commander. Before dangerous missions to the ice-bound planet of Poliahu, the deadly jungle world of Eden, and politically corrupt Mars, he was a simple recruit, fighting to make his mark in the elite Naval Special Forces…and was part of a top-secret military experiment that would change his life forever. Zero Point tells the tale of a young man faced with difficult choices and dangerous trials.

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.

After discovering a cache of Prothean technology on Mars in 2148, humanity is spreading to the stars---the newest interstellar species, struggling to carve out its place in the greater galactic community. On the edge of colonized space, ship commander and Alliance war hero David Anderson investigates the remains of a top secret military research station---smoking ruins littered with bodies and unanswered questions. Who attacked this post, and for what purpose?

When humanity reaches for the stars, our probes are destroyed. They crash into an incredibly advanced piece of technology: a massive force-field. Unknown beings have placed a barrier around our star and planets, enclosing us within. We’re locked inside a Great Sphere. Was this invisible obstacle built to imprison us - or to protect us? No one knows the truth, but it soon becomes clear the barrier has leaks. Aliens infiltrate and try to sabotage our efforts to escape our cage.

To Inquisitor Angel Xia, it was just another corporate killing on a backwater planet.

But as the web tightens, she receives a cryptic message from a computer program claiming to be a little girl in desperate need of her help.

A mysterious terrorist organisation has carried out several attacks against the Federation and Klingon Empire. Tensions are running high in a region already crippled by conflict. The perpetrators are tracked to the Lembatta Cluster, a mysterious region of space whose inhabitants, the Renao, regard the Alpha Quadrant s powers as little more than conquering tyrants. The Federation are desperate to prevent more bloodshed, and have sent their most powerful warship, the USS Prometheus, into the Cluster to investigate the threat before all-consuming war breaks out.

The year is AD 2790. With space elevators and giant orbital fleets hovering over Earth, open war looks inevitable, and people are anxious to get away. The lines are drawn, with the Confederacy in the East and the First World Alliance in the West. In hopes of finding a refuge from the looming war, the Alliance is sending Captain Alexander de Leon to explore an Earth-type planet, code-named Wonderland, but at the last minute before launch, a Confederate fleet leaves orbit on a trajectory that threatens both the mission and Alliance sovereignty.

In the year 2280, an alien fleet attacked the Earth. Their weapons were unstoppable, their defenses unbreakable. Our technology was inferior, our militaries overwhelmed. Only one starship escaped before civilization fell. Earth was lost. It was never forgotten. Fifty-two years have passed. A message from home has been received. The time to fight for what is ours has come.

Separated at birth, orphaned twins Peyton and Jai Foster’s lives couldn’t be more different. Raised by a billionaire, Peyton Foster has been taught that anything other than first place is failure.

The Earth lies in ruins in the aftermath of an extraterrestrial invasion, the land devastated by a desperate war with no winners between mankind and a race of vicious, intelligent creatures. The seas are drying up while the atmosphere corrodes and slowly cooks any life remaining on the now desolate rock. Food is scarce, trust even more so, and the only people left alive all have done horrific things to stay that way.

Avalon was the flagship of the Castle Federation in the last war, now 20 years past. The first of the deep space carriers, no other warship in the fleet holds as many honors or has recorded as many kills. No other warship in the fleet is as old. Accepting the inevitable, the Federation Space Navy has decided to refit her and send her on a tour of the frontier, showing the flag to their allies and enemies as a reminder of her glory - and then decommission her for good.
