After a year-long war bond tour of Terra Earth while his battle wounds healed, Lieutenant Fortis is ready to get back to the ISMC infantry. When fleet medical refuses to clear him for full duty, he faces a bleak future behind a desk in personnel or logistics. Instead, his mentor from Ninth Division, Colonel Anders, recruits Fortis for the intelligence, surveillance, and reconnaissance branch of the ISMC intelligence organization.

Fresh from fighting bugs and clones on Pada-Pada, Second Lieutenant Abner Fortis and Third Platoon look forward to some well-deserved liberty on Eros-69, a plutoid colony built to provide all the earthly pleasures available in the far reaches of space. When Fortis’ nemesis reroutes Third Platoon to Eros-28 instead, though, the Space Marines discover they’ve been sent to an industrial colony with limited R&R opportunities and no way back to the flagship. Everything

Abner Fortis joined the International Space Marine Corps for two reasons: to escape a life of drudgery building biodomes for his father’s company and to pay off several billion credits in student loans, which the ISMC promised to do. Every Space Marine starts out as a cherry, though, and Abner is no different. When he makes his first combat drop, or cherry drop, he’s a know-nothing second lieutenant added to the mission roster as an afterthought. 

Cam is a Marine, not a spy. That’s what he keeps trying to tell Fleet Intelligence. But when he and Vicky signed back up, they agreed to follow orders. And their orders are to keep working for the Corporate Security Force, and find out what the private paramilitary force knows about Zan-Thint's plans to use Predecessor technology against the Commonwealth. Stuck leading a crew of cutthroat mercenaries - who want nothing more than to slaughter the wildcat miners, and take their rhenium ore - Cam and Vicky try to figure out why the Corporate Council is really interested in the mine. 

Earth’s entire fleet and all her legions are conscripted by the Galactics. Centurion McGill of Legion Varus is among countless troops pressed into service as cannon fodder for the Empire. Not everyone on Earth is happy with the demands of the Galactics. Earth has built up her military for decades, and now she might lose everything in a foreign war no one understands. As the man who has killed more Mogwa than any other human in history, McGill is approached and given a mission. He has a fateful decision to make.  

Staff Sergeant Reverent Pelletier has been attached to the Congress of Humanity’s Home Guard, tasked with keeping the home system safe. Old rivalries and new enemies threaten the alliance, despite the counsel general’s mission to ensure humanity doesn’t fall into their old ways of conflict and war.

This is a new kind of war. The MDS and allies have withdrawn from the CoH, and they now want to become the center of gravity for humankind. The goal is to obtain localized wins, draw in more allies, and achieve victory, no matter the cost. With the alliance undone, Rev must fight a seemingly unwinnable war. But marines never quit. They never falter. They never give up. Humanity is about to experience a pivotal turning point in its history — one that will culminate in a discovery so profound that it may very well change everything. 

The war has only just begun. While rescuing a world from Centaur control, the Marines discover that not all humans on the planet are slaves. The Children of Angels believe their masters have been sent by the gods to lift up mankind. Humanity now has two enemies, one from the farthest reaches of the Galaxy and the other from within.

Chase Weston never would have thought that being the bodyguard for an archaeologist could be so dangerous - even this archaeologist digging for the remains of an alien civilization on another planet. But everyone wants what Dr. Angel Cortez has found. Because beneath the dirt and stone, an ancient mystery lies, a secret history, and a warning of an implacable alien enemy. And if the warnings are true, then corporate mercenaries and Sea Dragon commandoes are the least of Chase’s worries.

In the midst of humanity’s greatest fight for survival, old rivalries threaten to pull allies apart in a rush for rumored alien tech. With the newly weaponized Sergeant Reverent Pelletier and his Marine Raiders at the tip of the spear, only they stand a chance at holding the shaky alliance together long enough to meet the enemy. The Centaurs are on their way to destroy the very birthplace of human civilization: Mother Earth itself.

The Centaurs may no longer pose a threat, but a new war is on the horizon, though it hides in the shadows of two empires. Rumors of alien tech have set governments against each other, and with attention focused on defeating the Centaurs, criminal elements have gotten their tentacles firmly entrenched in the very fabric of civilization.

Even in space, crime still exists. After taking a Peacemaker job to find missing fuel, Perry finds something far more sinister than simple theft - a voice, crying out in a forge of heat and flame, and the discovery reveals a series of acts so vicious that nothing short of revenge will suffice.

A simple distress beacon.... A mining colony in the outer reaches.... Supposedly another routine deployment for Mike Barton of the Combined States Marine Corps, but what they find on the surface is unlike anything anyone had ever encountered. Horribly wounded in a battle with an unknown quantity, Barton only survives through a chance encounter with two special operators. As if the skirmish wasn’t enough, what comes next will be beyond his imagination. 

On the pastoral, backwater planet of Fimil Alpha, something or someone is eradicating the tribespeople of the Gauder Plains. Back on Earth, Albert Jenkins and his crew are enjoying the short-lived fame that accompanied their last adventure. What they don’t know is that by bringing back life-saving technologies to Earth, they’ve made powerful enemies who will do anything to see them quieted forever. With a target on their back, AJ’s team needs to make themselves scares.

Over the years, humans have grown used to their position within the empire, serving as soldiers and spacers for alien masters as well as building a place in the universe for themselves. But now, in the aftermath of a violent interstellar war that shattered the power of the Alphans, humanity has rediscovered its pride.
