The Omega War is in full swing. Earth has fallen to General Peepo’s army, and the surviving human mercenaries have taken refuge at the hidden Winged Hussars’ base in New Warsaw. As humanity begins to think about how to recover the planet, one thing is obvious - more powerful weapons of war will be needed in the effort. One of the keys to recapturing Earth will be the Raknar of Cartwright’s Cavaliers, but the power sources of many of the giant mecha have become unusable over the course of history.

The Omega War is in full swing. Earth has fallen to General Peepo’s army, and the surviving human mercenaries have taken refuge at the hidden Winged Hussars’ base in New Warsaw. On Earth, the defensive forces fight to keep the hearts and minds of their fellow humans, but Peepo’s plans are slowly converting the people to her way of thinking, and the Mercenary Guild troops continue to root out the forces arrayed against them.

War has come to the worlds of Humans. The rich planet of Tau-Rietzke, however, is far from Earth and the Mercenary Guild’s invasion, and its alien-registered mercenary companies are a safe haven for humans on the run. Organizations like the Midnight Sun Free Company. Having just completed another successful mission and taken possession of three Raknars, it was party time for Saisho Branco and the Midnight Sun personnel, and they were enjoying a little down time...until the war spilled over into their corner of the galaxy and two competing organizations showed up to steal the Raknars.

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. They’ve fled, leaving Sansar Enkh to go to the Mercenary Guild headquarters on Capital Planet to stand trial for humanity. 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.

Abraham Murdock left his home of Sheridan, Arkansas, at 17 to start a merc career that spanned almost 50 years, working for dozens of companies, killing aliens and getting paid across the galaxy. Near the end of his career, he landed a gig with Cartwright’s Cavaliers. The storied Four Horsemen unit was just coming back from near catastrophe, and the battle-proven Murdock was an ideal choice for their top sergeant. It would have been a perfect last contract, but then his dropship was destroyed in the Chimsa system, killing the flight crew and him. Or did it?

After a stunning victory at the Merc Guild shipyard of Golara, the leaders of the Four Horsemen mercenary units of Earth have decided it’s time to take back the colonies the Merc Guild has captured, and the Horsemen split up to liberate them. While the Merc Guild still has humanity outnumbered, Alexis Cromwell, the leader of the Winged Hussars, has incorporated the ships captured in Golara into her fleet, and she hopes the Humans can achieve local superiority across four systems with her new battleships and her Egleesius cruisers.

Lieutenant Magnus survives the harrowing rescue of his unit only to find himself charged with treason by the very military he’s pledged his allegiance to. Now, he must attempt to escort Piper to the Luma, homeward of Worru before dark forces discover her otherworldly abilities. But once there, Magnus finds himself confronting new enemies in the place he least expects to find them. Meanwhile, Awen uncovers a new plot that threatens to upend order throughout the galaxy. She and Magnus find their way to an alien world where they must work together to build a new team from the ruins....

With Alexis Cromwell shot in the back by her XO and the fleet in ruins, the Humans have run back to New Warsaw to lick their wounds, but the Merc Guild now knows the location of their hidden base, and they are in hot pursuit. Led by the New Era, a dreadnought built for the sole purpose of destroying humanity, they are an unstoppable force.

For Colonel Mulbah Luo and the Kakata Korps, their initial contracts with the Mercenary Guild had them defending Earth. Honest work, they were led to believe, keeping the citizens of Earth safe from alien pacification in their own way. As the occupation continues, however, their eyes are opened to the fact that the hand gripping their throat is slowly tightening.

When Todd’s critically damaged ship dropped out of hyperspace near the human colony world of Azure, he had no memory of his past. He didn’t know who he was, or even what he was, and the humans didn’t either. That didn’t stop the colonists of Azure - they took him in, anyway...even though they didn’t understand how he could do some of the things he could do. Todd and his descendants consider themselves human - eight-armed and water-breathing - but human, nonetheless. After 70 years living among humans, Todd’s descendants are going back out into the Union to make their mark.

Cam Alvarez is a Drop-Trooper. A warrior-knight wrapped in the futuristic armor of a high-tech battlesuit, and he’s one of the best. When he’s promoted to sergeant and asked to become a leader, he faces a whole new challenge. The Marines are striking deep into enemy territory, and the casualties are mounting. Cam is torn, knowing his job is to follow orders and carry out the battle plan, even if he doesn’t agree with it. But his squad has become his family, and now he’s being asked to lead his family into battle, knowing it will mean their deaths. 

After Lieutenant Magnus awakes from the orbital strike that nearly killed him, he discovers that a small contingent of his Marine platoon has also survived. Hope glimmers as he devises a plan to rescue them. But when Magnus learns that his men are being held hostage by a deadly tribe, he fears the worst. Aided by volunteers from a group of elite Marauders, Magnus must attempt to cross the hostile city of Oosafar. Time is running out...and he has no choice but to undertake the most deadly urban assault of his career.

All Cam Alvarez has known is war. For three years, he’s fought the marauding alien Tahni on one God-forsaken planet after another, leading a squad of armored Drop Troopers. But the war is about to change. Cam is an officer now, fresh out of OCS and taking charge of his old platoon, and things have reached a tipping point. Instead of fighting a desperate holding action against the enemy, the Commonwealth is finally ready to take back the human colonies the Tahni seized early in the war. To free the people the enemy have kept as human shields.

The mission is simple. Escort an emissary to an intergalactic peace summit. Try not to get in the way. Lt. Magnus and his 79th Recon Team have certainly handled worse, after all. But when an explosion rocks the tower and sends everyone into a panic, Magnus and his asset find themselves cut off from the rest of the team. Worse still, a dying alien chieftain gives them a priceless drive of intel, marking them for death. The mission has officially changed. With enemies on all sides, Magnus must do everything in his power to protect the emissary and escape the tower.

For small-time street hustler Cam Alvarez, the choice is simple. He has no family, no friends, no place in the world...nothing to lose. When his latest con results in the death of a cartel hitman, Cam opts to join the Marines and leave Earth to fight a vicious alien enemy.
