At a time when Humans were just starting to venture forth into the Galactic Union as mercenaries, Martin Quincy survived long enough to do something no one else had - he retired. There was only one problem: He got bored. After battling aliens for many years - killing aliens and getting paid - retirement didn’t suit him, and he decided to strap on the combat armor and go back to the stars. Along with his old friend Kal, Martin joined Cartwright’s Cavaliers, humanity’s best merc company. Life was exciting! But he got bored. Again.

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.

The Peacemaker-enforced ceasefire brought an end to the hostilities, but not a resolution, and now it’s up to the Four Horsemen to forge a lasting peace. Alexis Cromwell, despite her pregnancy, heads off to Capital with Nigel Shirazi to obtain justice from the enigmatic Mercenary Guild Council, but when they arrive, they’re quickly embroiled in galactic politics, and find out the situation is far, far worse than they could possibly have imagined.

Heir to one of the leading "Four Horsemen" mercenary companies, Jim Cartwright is having a bad year. Having failed his high school VOWS tests, he's just learned his mother bankrupted the family company before disappearing, robbing him of his Cavalier birthright. But the Horsemen of eras past were smart - they left a legacy of equipment Jim can use to complete the next contract and resurrect the company.

On the African savanna, the male lion is the lord who watches over his family, while the females of the clan do the real work. Joel “The Lyon” Lyons thought that owning a mercenary company would be similar—he could sit back and allow the Lyoness to run the Pride. Everything would go well, money from successfully completed contracts would flow like water into his bank accounts, and everything would be as easy as it had been for him when he’d owned a chain of highly successful restaurants.

Before Hr'ent Golramm became a legendary Enforcer for the Peacemaker Guild, he was a mere candidate. Granted, he was a particularly unusual candidate - only six Oogar had ever successfully graduated from the Peacemaker Academy on Ocono, and Hr'ent would be the seventh. Every candidate must pass a commissioning mission in order to graduate, though, and Hr'ent's is unsolvable. The Pushtal of Vorrhurna were once one of the Mercenary Guild's 37 races.

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.

Caleb is a former Marine Raider and commander of the Vultures, a search and rescue team that's spent the last two years pulling high-value targets out of alien-ravaged cities and shipping them off-world.

From scratch.
