Science Fiction Adventure War Space Opera

The powerful alien empire of the Gumalagians turns their attention to the United Interplanetary Republic. While Carter has faced dangerous opponents, nothing could prepare him for what’s to come. He must find allies and grow stronger — without sacrificing the people he loves. Along with an audacious and alluring Admiral, Carter races against the clock to assemble a fleet that can save them all.

Jack Bennet returns from the war to find the life he left behind has moved on without him. The only option he has to make ends meet lies in a military surplus junkyard starship. What’s a former Combat Search and Rescue soldier to do? Fix up the ship, hire the cheapest pilot—a notorious drunk—and take the first contract that comes up: collect a bounty on one of the most ruthless killers in the Pirate Worlds, a place crawling with thieves, cutthroats and con artists whose primary language is violence. Jack must abandon his nice guy persona, or exploit it, if he is to survive.

In space everyone can hear you sing. A century ago, intelligent space-faring life was nearly destroyed during the Sentience Wars. To bring the shattered worlds together in the spirit of peace, unity and understanding, the Metagalactic Grand Prix was created. Part concert, part contest, all extravaganza, species far and wide gather to compete in feats of song, dance and/or whatever facsimile of these can be performed by various creatures who may or may not possess, in the traditional sense, feet, mouths, larynxes or faces. 

Having witnessed the seemingly unconquerable power of the Progenitors first hand, Commander Reeves and Major Kane have an opportunity to tilt the balance of war in their favor. And they intend to take it, no matter the risk or the cost. Despite the setback at the Progenitor world, Reeves is determined to find the "smoking gun" that proves the Sa’Nerra are acting under the influence of an ancient power. Only then can he unite the realms against their enemy. But in order to achieve this, Reeves must pierce the veil of Shadow Space and discover the true scale of the alien armada.

Lieutenant Xedro Farren is a Primaris Marine, stronger and more adept than even the Space Marines his brotherhood is sent to fight alongside. As the Dark Angels and the Primaris Marines fight a trauma-scarred force of T’au hellbent on destroying their former allies, the true quarry becomes clear - the shadowy instigator of a psychic curse that could plunge a string of Imperial planets into madness. As worlds burn in the fires of battle, an unthinkable pact is struck, with the Primaris Marines peeling back layer after layer of deceit to find the appalling truth.

Strange signals from the edge of the solar system draw the carrier ECS Vanguard into the darkness beyond the planets. There, humanity faces a new alien threat—the Blight. They have come to exterminate what they believe is their ancient enemy's latest puppet civilization. Earth struggles to control the skies with fighters and throws its Lizard shock troops into bloody ground battles. While the war rages, Flex must uncover the truth about the hyperspace rivers connecting the stars, the mysterious Cure that terrorized Venus, and why the Blight believes humanity is already enslaved.

Tensions amongst the six realms are running high as the galaxy witnesses the overwhelming might of the Sa’Nerra armada. The Quarr race are facing defeat, and no one wants to be next. Desperate to find a way to unite the realms against the Sa’Nerra, Commander Reeves and his team take the warship Invictus on a quest to learn about the mysterious and ancient Progenitors—the puppet masters manipulating the war. With threats from the Sa’Nerran Imperator and the New Earth Movement looming over him at every turn, Reeves is still struggling to embrace his legacy.

All pretenses of diplomacy have crumbled, and Concord is no longer considered neutral territory. The Imperator is coming, and he intends to reduce the station to dust, forcing Commander Reeves to order an emergency evacuation. But old enemies linger on in the background. Not only must Reeves contend with the Sa’Nerra, but a final showdown with the Lord of Night appears inevitable, and the crime kingpin will stop at nothing to get his revenge. Meanwhile, the Sa’Nerra have invaded Bastion Federation space with thousands of warships and near-unlimited reserves.

Finally possessing the ability to enter the Progenitors’ shadow realm, Commander Reeves and Major Kane embark on a daring mission into the heart of enemy territory. However, en route they must detour to the Quarr planet of Vroxxa, which is under Sa’Nerran occupation. There they will learn the true horrific purpose of the "atmosphere acclimators" the aliens have installed on dozens of worlds. They will also discover the sickening depth of the Sa’Nerran’s cruelty, forcing Reeves to again confront his dark side.

The Emperor's vision of mankind ascendant lies in tatters. The Great Crusade is naught but a fading memory. The dream of Unity is no more. But with Horus's rebellion spreading to every corner of the Imperium and war engulfing new worlds and systems almost daily, there are some who now ask: were the signs there to be seen all along?

The people of Earth now know that the human Colonial Union has kept them ignorant of the dangerous universe around them. For generations the CU had defended humanity against hostile aliens, deliberately keeping Earth an ignorant backwater and a source of military recruits. Now the CU’s secrets are known to all. Other alien races have come on the scene and formed a new alliance - an alliance against the Colonial Union. And they’ve invited the people of Earth to join them. For a shaken and betrayed Earth, the choice isn't obvious or easy.

The Ravennox are still out there. But thanks to Darius Spann and the Superba, Lawson and the other forces of the newly-restored Cygnus Realm face another, far more immediate threat. Spann and his Superba allies still hold sway over a huge swath of human territory, declaring it all Imperial space. Humanity is split, the Realm on one side and the Empire on the other, both claiming to be led by the Messenger. With neither able to land a decisive blow to knock out the other, a cold war now simmers between these two competing visions for the future.

Across the six-planet expanse of the Gaia System, the Earthlike Gretia struggles to stabilize in the wake of an interplanetary war. Amid an uneasy alliance to maintain economies, resources, and populations, Aden Robertson reemerges. After devoting fifteen years of his life to the reviled losing side, with the blood of half a million casualties on his hands, Aden is looking for a way to move on. He’s not the only one. A naval officer has borne witness to inconceivable attacks on a salvaged fleet. A sergeant with the occupation forces is treading increasingly hostile ground.

The cold war smoldering between the Realm and the Empire drags on. Both sides now turn to the distant spinward stars for a way to break the deadlock. Cryptic signals from deep space hint at powerful civilizations, and potential allies to turn the tide in favor of one side or the other, propelling it to victory. But who—or what—are these mysterious powers?

Humans expanded into space...only to find a universe populated with multiple alien species bent on their destruction. Thus was the Colonial Union formed, to help protect us from a hostile universe. The Colonial Union used the Earth and its excess population for colonists and soldiers. It was a good arrangement...for the Colonial Union. Then the Earth said: no more.

Carter Ash must take the fight to his enemies—or risk losing everything. As the leader of the United Interplanetary Republic, he knows the only chance for his people’s survival is defeating the Empire of Humanity. But the Emperor and his army are much stronger than Carter knows—and they will stop at nothing to wipe the evidence of his embarrassing betrayal from the face of the galaxy. Now, they must pin their hopes on a daring mission into the heart of danger to keep the Empire from attacking. With a sultry sniper at his side, can he win an unwinnable fight?

All alone in a dangerous galaxy — a new civilization struggles for survival. War rages across the galaxy. Difficult diplomacy is all that keeps Carter Ash and his people safe from the threats around them. They need all the time they can get to build their home, because every day new, hungry eyes turn towards their fledgling government and their resource rich moon. Even now, multiple invading fleets race towards Carter’s home — and it’ll take everything he’s got to be ready for the fight of his life. And to top it off, a blast from his past arrives, complicating everything.

As the Greshian Empire broadens its reach, pockets of rebel forces form to combat their tyrannical rule. Death before dishonor becomes the last gasp of dying civilizations. When two sides of the war converge, surviving becomes common ground for unlikely allies. As the tides turn and they become refugees on the run, the ragtag crew of the Replicade must lean on each other - no simple task after years of war and hate.
