Humanity has spread to other worlds, yet in its ambition it's unity shattered, if it was ever even there to begin with. Humanity's domains remain split between the United Alliance of Planets and the Conglomeration of Corporate Authorities. The two governments lash out at each other in ceaseless conflict, at the cost of countless lives. Furthermore, the war has left a power vacuum closer to home, as a terrorist organization known as the Syndicate rises to power.

Captain Keyes is loved by the public but hated by Command. He captains the UHS Providence, an aging supercarrier and the last human ship not dependent on dark tech - technology humanity has used to rule over the galaxy since barely defeating the Ixa in the First Galactic War. Dominance has come at a cost. Over the decades, old allies have grown resentful, and when dark tech itself fails, Captain Keyes’ predictions start coming true: those old allies are now enemies.

One starship will either save Earth or destroy her. A century ago our star erupted, destroying Earth's wormhole network and closing off trade with her colonized planets. After being out of contact with the younger worlds for so many years, humanity is shocked when a huge ship appears at the edge of the solar system. Our outdated navy investigates, both curious and fearful. What they learn from the massive vessel shocks the planet.

They hunt us. They bomb our worlds for target practice. A star cluster in the constellation of Orion rotates once every 1,000 years. Those who rule there have an ancient tradition: When each cycle ends, they train their fleets by spilling the blood of lesser beings. The enemy fleets are coming again. In response, the Rebel Worlds gather their starships to face the terrifying threat, and this time humanity is asked to stand with them. The last time they considered Earth, Vikings in longboats were raiding English coastlines. Today, we're less primitive. Today, we're a target.

The Hundred Worlds have withstood invasion by the relentless Hok for decades. The human worlds are strong, but the Hok have the resources of a thousand planets behind them, and their fleets attack in endless waves. The long war has transformed the Hundred Worlds into heavily fortified star systems. Their economies are geared for military output, and they raise specialized soldiers to save our species. Assault Captain Derek Straker is one such man among many.

Jason Burke was a man hiding from himself in a small cabin high in the American Rocky Mountains when his simple, quiet life was shattered one night by what he first assumed was an aviation mishap. But when he investigates the crash, what he finds will yank him out of his self-imposed exile and thrust him into a world he could have never imagined.

Out of the blue, a young Space Fleet officer's dream becomes reality: He's made captain of a starship. Just in time for the return of humanity's most terrible enemy, after 50 years of peace. To survive against this enemy, Captain Tad Thatcher will have to do more than learn how to become an effective commander, or how to wrangle his wayward crew. He will need to reinvent space combat. From scratch.

Aliens exist...and, as it turns out, most of them aren’t that friendly. Jacob Brown wasn’t even born yet the first time they attacked Earth. He was only 14 the second time it happened. When Earth finally came together and fielded its first spaceborne military, Jacob didn’t hesitate to volunteer. Serving aboard a mighty starship, he’d be able to defend his planet - and his family - when, inevitably, they came again.

The year is 2650. Seventy-five years ago, an alien fleet attacked Earth. Without warning. Without mercy. We were not prepared. Hundreds of millions perished. Dozens of cities burned. We nearly lost everything. Then the aliens abruptly left. We rebuilt. We armed ourselves. We swore: never again. But the aliens never came back. Until now. With overwhelming force the aliens have returned, striking deep into our territory, sending Earth into a panic.

We had 20 short years of peace. Twenty years to put worlds back together. Twenty years for Captain Vin Husher to convince us the aliens would return. We didn’t listen. Warmonger, we called him. Washed up, we called him. But now, the enemy has returned, with high-tech weaponry well beyond anything of which humanity has dreamed. If Husher and his ragtag crew can’t manage to stop them, they will smash us.

When Klingon commander Kruge died in combat against James T. Kirk on the Genesis planet back in 2285, he left behind a powerful house in disarray - and a series of ticking time bombs: the Phantom Wing, a secret squadron of advanced Birds-of-Prey; a cabal of loyal officers intent on securing his heritage; and young Korgh, his thwarted would-be heir, willing to wait a Klingon lifetime to enact his vengeance.

When the Colony on Hayden's world went black, a team was sent to investigate. It was supposed to be a training mission: skip in, find out the Casimir Transmitter had gone dead, report back and wait for resupply from the Fleet. By the time the only surviving member of the team made landfall, it was spectacularly clear that this wasn't a training mission.

They slept for hundreds of years, dreaming of a new home in the Andromeda galaxy. When finally they awake, their dreams of peace are shattered. These colonists - turian, salarian, asari, human, and more - face an uncharted galaxy and threats beyond understanding.

High school senior Tanner Malone has bombed the Test, a high-stakes exam that establishes how much he owes for his corporate-funded education. Burdened by a crushing debt that rules out college, Tanner enlists in the navy of Archangel, a star system with four terraformed worlds. But he hasn't factored in the space pirates.

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.

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.

The plot by the Galactic Union’s Mercenary Guild against the Four Horsemen has culminated in an invasion of Earth. Faced with an overwhelming force, the human mercs had no choice.

On the run, Jim Cartwright and Nigel Shirazi have travelled to the Winged Hussars’ secret base of New Warsaw, in an effort to convince Alexis Cromwell to join the fight, while the other mercenaries who escaped the fall of Earth have gone to the perceived safe haven of Karma.

Mars is supposed to be dead. Bizarre quakes are rumbling over the long-dormant tectonic plates of the planet, disrupting its trillion-dollar mining operations and driving scientists past the edges of theory and reason. However, when rocks shake off their ancient dust and begin to roll seemingly of their own volition carving canals as they converge to form a towering structure amid the ruddy terrain, Lt. Jain and her JSC team realize that their routine geological survey of a Martian cave system is anything but. The only clues they have stem from the emissions of a mysterious blue radiation, and a 300-year-old journal that is writing itself.

As a lifer in the Imperial Navy, fighting in a war that has lasted generations, Lieutenant York Ballin's only hope for an honorable discharge is the grave. Neither the Empire nor the Directorate seems to care that millions have died or that millions more are doomed as hostilities continue.

The 200 years' (and counting) peace was a time of tranquility that hasn't been seen since...well, ever. Mankind in the Galactic Age had finally conquered war, so what was left for the military to do but drink and barbecue? That's the kind of military that Sergeant R. Wilson Rogers lived in before he left the fleet to become a smuggler. But it turns out that smuggling is hard. Like getting-arrested-for-dealing-with-pirates-and-forced-back-into-service kind of hard.
