Space Military Science Fiction

The Indomitus Crusade has brought the Emperor's vengeance to thousands of star systems. The fleets and armies under the leadership of Roboute Guilliman fight for the survival of humanity against the forces of the Chaos Gods. But the traitors and heretics are not the only foe looking to destroy the rule of Terra. Xenos prey on human worlds in numbers not seen for millennia. Worst amongst them are the rampaging orks, whose migration conquests threaten to reverse the many gains of Fleet Primus.

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.

The People's Republic of Haven's sneak attack on the Kingdom of Manticore has failed. The Peeps are in disarray, their leaders fighting for power in bloody revolution, and the Royal Manticoran Navy stands victorious.

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.

Padawan Iskat Akaris has dedicated her life to traveling the galaxy alongside her master, learning the ways of the Force to become a good Jedi. Despite Iskat’s dedication, peace and control have remained elusive, and with each setback, she feels her fellow Jedi grow more distrustful of her. Already uncertain about her future in the Jedi Order, Iskat faces tragedy when her master is killed and the Clone Wars engulf the galaxy in chaos.

Unknown aliens attack Earth. Their planet is uncharted, mysteriously having avoided detection for centuries. It's a world packed with the most vicious aliens humanity has yet to encounter. James McGill has discovered: Death World.

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.

Long before the coming of the Imperium, the realm of Ultramar was ruled by Roboute Guilliman, the last Battle King of Macragge. Even after learning of his true heritage as a primarch son of the Emperor of Mankind, he strove to expand his domain as efficiently and benevolently as possible, with the XIII Legion Ultramarines as his alone to command.

For eight years, Commodore Honor Harrington was in the forefront of the battle between the Star Kingdom of Manticore and the powerful People's Republic of Haven. Then she was captured and publicly executed. But Honor is far from dead, what's more, she's going home and taking her people with her.

It's hard to give peace a chance when the other side regards conquest as the only option and a sneak attack as the best means to that end. That's why the Kingdom of Manticore needs allies against the Republic of Haven, and the planet Grayson is strategically situated to make a very good ally indeed. But Her Majesty’s Foreign Office overlooked a “minor cultural difference” when they chose Honor Harrington to carry the flag: women on the planet of Grayson are without rank or rights and Honor’s mere presence is an intolerable affront to every male on the planet.

The Imperium grip is slipping, thanks to Will's unexpected ability as a Void Drifter. But in revealing his abilities, Will may have put his home planet, a backwater most of the galaxy didn't even know existed, on the frontlines. But Earth is not as defenseless as it seems. An enigmatic billionaire, aware of the true nature of the Imperium's galactic menace, has been secretly building a defensive fleet. Still more fleets have been secretly constructed in the far reaches of the galaxy.

Removed from the concerns of the galaxy at large and regarding the Warmaster's unfolding Heresy with cold detachment, he has dedicated his hollow existence to the preservation of all the knowledge once held in the great libraries of Tizca, should mankind ever seek such enlightenment again. But his sons can see the change in their primarch - he is a broken soul whose mind and memories are slipping away into the tumult of the warp.

Randall Munroe's past won't stay dead. Born Tyler Callas, the pampered heir of a Corporate Council scion, he fled that life and adapted the new identity of Randall Munroe so he could join the Commonwealth Space Fleet Marine Corps' elite Force Recon unit in the war against the alien Tahni Imperium. But when he returned from the war, his old life found him. His mother, Corporate Council Executive Patrice Damiani, tracked him down and tried to return him to her web of control, even if she had to have his personality altered by drugs and psychological brainwashing to do it.

Get ready to experience two more origin stories in the Backyard Starship universe.

No one wanted another war. Thomas Theisman didn't. Not after risking his life to overthrow the Committee of Public Safety's reign of terror and restore the Republic of Haven's ancient Constitution. Baron High Ridge didn't. The Prime Minister of Manticore was perfectly happy with the war he had. No one was shooting anyone else at the moment, and his government could continue to milk all those "hostilities only" tax measures for their own partisan projects.

Years after defeating aliens bent on burning down the galaxy, the Interstellar Union is breaking apart, its member species undermining each other at every opportunity.

Surrounded by a bioengineered super-species and unable to return home, Husher must draw on decades of experience just to keep his people alive.

The former warship Trouble Dog and her crew of misfits is called upon by the House of Reclamation to investigate a distress call from the human starship the Lucy's Ghost. Her crew abandon their crippled ship and seek refuge aboard an abandoned, slower-than-light generation ship launched 10,000 years before by an alien race. However, the enormous ship contains deadly secrets of its own.

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.

The crews of Jean-Luc Picard, Benjamin Sisko, Ezri Dax, and William Riker unite to prevent a cosmic-level apocalypse - only to find that some fates really are inevitable.

In the aftermath of Moldark's death and Soldark's creation, Magnus, Awen, and the rest of the Gladio Umbra must follow the sinister warlord back through the quantum tunnel into metaspace. Questions swirl around the enemy's ultimate intentions, as do the fates of those bound to serve the malevolent leader. What awaits the gladias, however, may prove to be more than they can handle.
