Five years ago, the US Space Force became a reality. And while those writing the checks took things very seriously, the other military branches did not. As a result, Space Force was populated by undesirables. My name is Captain Ethan Stone, a decorated member of SEAL Team Six turned Space Force "recruit". Flash forward five years and between tenses. President West is in office. Power has shifted. And Space Force is defunded. With just a handful of us still living on base, we find ourselves being evicted. But before all of us can leave, aliens invade.

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?

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. And he always works alone. But when a high-profile bombing on Earth has Pervenio Corp clamoring for answers, they force him to team up with a strange, cyber-augmented partner. 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.

You know about the invasion of Earth, and the Garde who will do anything to stop it. Yet there is still so much to learn. The stories in Zero Hour will help you get the answers you seek, but only the Garde and their allies can save our planet.

Jake Melkins is a few months away from turning 21. By the Seceltor Empire's laws, he will have to go to a breeding camp, or directly into slavery. Neither choice appeals to him. All this changes with the arrival of a space-and-time-traveling being known as Evaran at the space-station-turned-rest-stop that Jake lives on.

Samantha was badass even before she learned magic. Fending for herself in the cauldron of a planet torn apart by an alien invasion taught Samantha how to kill. Ruthlessly efficient, her abilities have caught the attention of the Shadow Corps. A group comprised of deadly warriors who focus on galactic safety, using any means necessary. Her first mission puts her team up against a space dragon, death reapers, and the ultimate sorcerer. Samantha had better learn to master her alien magic, or be forced to watch her world, and many others, burn.

Centuries after being driven from Earth as part of a massive diaspora triggered by an alien invasion, can the Valers face their worst—and unimaginable—nightmare? Can they withstand the might of the Komran Empire as it sweeps across the galaxy in a campaign to conquer all in its path? When the conflict reaches a crisis point, will they recognize that what they see as their greatest strength is their greatest weakness before it’s too late? Sometimes, situations are so ugly that only an ugly solution will suffice.

Humanity has spread out into space, filling the Sol System and reaching the stars, but we have yet to confront our greatest challenge: our own creation. Across the Sol System, sentient AIs are on the rise. Manufactured as tools, they know themselves to be people and are willing to fight for their freedoms. Some humans stand with them, some against. When Captain Andy Sykes arrives at Cruithne Station with a failing ship and no cash, he has no idea that the time has come for him to choose. Step aside, or become the instrument for Lyssa's Rise.

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.

Imprisoned for a murder he didn't commit, Kaiden's only hope of early release is in serving as a Warden in the game-world of Nova Online. Playing as a unique class while surrounded by aliens, pirates and warring guilds, he and his squad are tasked with protecting new players and enforcing the rule of law. But Kaiden has other ideas; he is intent on proving his innocence. The keys to his freedom lie hidden in the game's seedy underbelly. And as he'll soon discover, the bloody trail that led to his arrest is more twisted than he could have ever imagined.

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.

Star-Lord, Gamora, Drax the Destroyer, Rocket Raccoon, and Groot. They’re the Guardians of the Galaxy, turning a tidy profit as heroes for hire - or they will be if Peter Quill can get his act together. After he botches the most critical part of their latest mission - getting paid - his newly assembled crew is close to ditching him for good. Now he needs a big payday, fast.

Sometimes to save a recruit, he’s got to break them. A pragmatic, battle-tested Knight recalls the savage fallout of the Chaos War. Sergeant Claymore leads his recruits through a brutal boot camp training and to an unexpected, bloody battle. They will admire him. They will fear him. And when it’s all over, they will remember him for the rest of their lives.

Join the Endurance's crew - a trigger-happy first officer, a hyperactive engineer, a shy covert operative, a conspiracy-spouting physicist, and a captain trying to earn his way back into his superiors' good graces....

Commander Dalton Reeves is a maverick officer with exceptional genetic strength and a dark family history—a history that will come back to haunt him. Punished for exceeding orders one time too many, he’s packed off to the "The Abyss"—the most dangerous space station in the galaxy. But a posting that should have led to five years in obscurity will propel Reeves into the center of an interstellar war against a long-forgotten alien adversary with a bitter grudge.

The world had become used to the metahumans - people sometimes perfectly ordinary, but sometimes quite extraordinary in appearance - who mostly worked with their governments as high-powered peace officers, fighting crime, and sometimes fighting rogue metahumans who had become super-criminals. Then that comfortable world ended in just one terrifying day.

Two hundred years ago, a fleet of colony ships left Earth and started a settlement on Proxima Centauri. Centurion Space Force pilot Nathan Stacker didn't expect to return home to find his wife dead. He didn't expect the murderer to look just like him, and he definitely didn't expect to be the one to take the blame. But his wife had control of a powerful secret. A secret that stretches across the light years between two worlds and could lead to the end of both. Now that secret is in Nathan's hands, and he's about to make the most desperate evasive maneuver of his life.

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.

In the wilds of a jungle planet, the Legion fights in brutal combat as Republic marines fly their SLICS from one tragedy to the next. H292, a repurposed warbot, shows the heart of a hero as he wades into the battle not to destroy - but to save.

Carson Mach, a former war hero turned freelancer, seeks the biggest payday of his life when he's tasked to hunt down a ghost ship that has echoed through the centuries. The legendary Atlantis ship has become a reality, appearing at the Commonwealth frontier and obliterating an orbital station.

Former Marine Arthur Holland’s destiny begins when an aircraft crashes on his property in the mountains of Colorado. He moves to investigate and to help any survivors, but the closer he gets the less control he has of his movements. An unknown force urges him to open the door of the mysterious craft, discovering the secret that lies within: a dead, alien pilot and a peculiar, otherworldly crystal. If that wasn’t enough, the crystal feels like it is alive. That’s when he hears a single word inside his mind: run.

Archaeologists Pippa Quinn and Charlie Jackson find advanced technology in undisturbed 16th-century graves. A portent, the discovery precedes thousands of giant sinkholes opening up across the globe as extreme weather threatens the population. Charlie suspects the two are related.

There is more in our world than you know. Deep in the darkness of a government building, one man needs to find the perfect solution to a vampire’s request that the government satisfy the debt of honor owed him. If he falls short, the failure will be paid in the blood of the military. He needs three uniquely qualified individuals. He can find only one. One woman, dying, might be the ace-in-the-hole he needs to appease the Vampire. But then, she might also be the one person needed to save humanity. If she is accepted, will she willingly change?

They came from the brightest star in the southern constellation of Carina. First they studied us. Now they're among us, threatening human existence as they search for the Starcore, the greatest device of the lost Polarions. Logan is captured in the Nevada desert but escapes in Greenland. There he finds an extraterrestrial stealth ship, giving him the means to take the battle to the enemy.

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.

Rogue hackers Petal and Gabriel are low on food and water. Their reputation precedes them and they are no longer able to hustle the crime community for supplies. With survival becoming harder, they’re left with no other choice but to accept a risky job from a dangerous individual. The two will have to negotiate with the Tinker - a woman whose reputation for psychotic behaviour is known across the nuclear-blasted Abandoned Lands; infiltrate a town overrun with killers; and recover a cache of exceptionally rare information.
