Space Military Science Fiction

When your starship's computer undergoes a catastrophic meltdown, light years from help, it's bad. When you are that ship's computer, it's worse. Fresh from the destruction of the colony they were assigned to protect, the UES Interchange is now hurtling toward Proxima Centauri, there to rally reinforcements against the tide of revolutionary rage currently rocking the galaxy. But when they arrive, they find the heart of galactic civilization eerily quiet...and empty. At the same time, Sergeant Henry Morgan, the ship's computer, is utterly unresponsive.

Ex-Army paratrooper Griffin “Fin” Brooks thought he left danger behind when his battlefield injuries forced him to pursue a new career in marine biology. But one fateful night off the coast of South Africa, a ship nearly crashes into him and his loyal golden retriever, Jacques. Not just any ship. A starship. Though its alien pilot is dead, the rare extraterrestrial animal inside is not. Fin learns the creature is being smuggled across the galaxy when a pair of interstellar visitors respond to the crash. But those same investigators accuse Fin and his dog of crimes he didn’t even know existed.

The Traitor Host of Horus Lupercal tightens its iron grip on the Palace of Terra, and one by one the walls and bastions begin to crumple and collapse. Rogal Dorn, Praetorian of Terra, redoubles his efforts to keep the relentless enemy at bay, but his forces are vastly outnumbered and hopelessly outgunned. Dorn simply cannot defend everything. Any chance of survival now requires sacrifice, but what battles dare he lose so that others can be won? Is there one tactical stroke, one crucial combat, that could turn the tide forever and win the war outright?

Major Jimjoy Earle Wright, secret agent of the Empire, is intelligent and highly trained. But he succeeds all too well in overthrowing a military dictatorship - and the result is a new government inimical to the Empire and disgrace for Jimjoy. After surviving two assassination attempts, Jimjoy realizes that it's his own imperial superiors who want him dead; that, in fact, his worst enemies could become his best friends. He fights his way to safety on the planet Accord, where the Ecolitan Institute wins his loyalty and changes his identity.

Peacetime can be a rough adjustment for the battle-hardened Merry Band of Pirates.

Especially when aliens don’t get the memo that the shooting is over.

Captain Axel Finn is bored out of his mind being a peacetime hero, so when a murdered scientist's final message reveals coordinates to a mythical planet, he and the Trash Squid crew jump at the chance for a new adventure. They've got a small window to reach it before it vanishes, and they're not the only ones racing to get there first.

Terminal Lance Lucky Lee Savage likes his life. Sure, doing PT hungover is a pain, but no one can dodge responsibility like he can - or sweet-talk the cooks into giving out double rations.

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.

A mysterious wave of light has swept across the globe, erasing all animal life from the planet in an instant. Now, two survivors are all that remain—one stranded on a ravaged Earth and the other newly rescued from the decaying International Space Station. Their struggle for survival and reunion soon spirals into something much larger, plunging them into a cosmic battle that transcends time, space, and even reality itself.

A great darkness has befallen the galaxy, and the armies of Chaos are rampant. To survive, humanity must retaliate and take back what they have lost. By the will of the reborn primarch, Roboute Guilliman, is the Indomitus Crusade launched - a military undertaking that eclipses all others in known history. From the Throneworld of Terra does the Avenging Son hurl his fleets, their mission the very salvation of mankind.

The isolated forge world of Diamantus faces a threat of apocalyptic proportions – a warped and mutated space hulk infested by the forces of Chaos, commanded by the monstrous datagnost Voldire, disciple of the dread demigod Vashtorr the Arkifane. As the battle-weary Carcharodons make their stand alongside the Adeptus Mechanicus, horrors and nightmares raining down around them, the Space Marines must confront their place within this new Imperium, and destroy the hulk before Diamantus is lost.

The galaxy remembers Hadrian Marlowe as a hero: the man who burned every last alien Cielcin from the sky. They remember him as a monster: the devil who destroyed a sun, casually annihilating four billion human lives - even the emperor himself - against Imperial orders. But Hadrian was not a hero. He was not a monster. He was not even a soldier. Fleeing his father and a future as a torturer, Hadrian finds himself stranded on a strange, backwater world.

It is the Dark Age—3139—and the famed mercenary regiments of Wolf's Dragoons have returned to the employ of House Kurita after a century of bitter enmity. Somehow, mercenaries and Kuritans must find a way to work together in a combined invasion of the Dragon’s oldest enemy, House Davion. Thrust into the middle of this new conflict, Colonel Henry Kincaid is surprised by the commonalities—duty, honor, expediency—the Wolves and Combine forces share.

The galaxy was once terrorized by the Sturm, a group of “species purists” intent on destroying any human with genetic or cybernetic enhancements. Fashioning themselves as the one true “Human Republic,” the Sturm cut a bloody swath across the stars, killing billions before finally being defeated and driven into the far reaches of Dark Space. Centuries of peace bred complacency. Everyone believed the Sturm had died out in the Dark. They were wrong.

The lines. No ship can traverse the void without them. Only linesmen can work with them. But only Ean Lambert hears their song. And everyone thinks he's crazy.... Most slum kids never go far, certainly not becoming a level 10 linesman like Ean. Even if he's part of a small and unethical cartel, and the other linesmen disdain his self-taught methods, he's certified and working. Then a mysterious alien ship is discovered at the edges of the galaxy.

We hide in shadows. Our planet is lost. We are the last humans, and we must go home. Two thousand years ago, aliens destroyed Earth. Our fleets shattered. Billions died. The last humans fled a burning planet, heading to the stars. Today we are still refugees. Hungry. Afraid. Our enemies hunt us everywhere. So we hide. On distant asteroids. In rundown space stations. In deep caves on frozen worlds. And we dream. Of green hills. Blue skies. Golden fields. We dream of Earth. And for the first time, we have hope.

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.

When asubatomic physics experiment causes a massive explosion, interdimensional gateways open in Florida - and aliens pour out. Some intend to bring Earth to its knees. Others seem willing to help, but will annihilate the planet if Navy SEAL Command Master Chief Robert Miller can't stop the menace from spreading.

The war for the fate of mankind blazes on. Though the outer defences have fallen, the walls of the Palace itself remain inviolate as Rogal Dorn, the Praetorian of Terra himself, uses every known stratagem and ploy to keep Horus' vast armies at bay. In Perturabo, the Traitor siegebreaker, Dorn faces an adversary worthy of his skill. A terrible, grinding attrition ensues. The crucial battle for the Lion's Gate spaceport is at the heart of this conflict. With it in their possession, the Traitors can land their most devastating weapons on Terran soil. Dorn knows it must not fall.
