War is breaking out everywhere as planetary governments declare independence, entire sectors slip out of contact, and warlords battle for power. The remnants of the once-great Empire are tearing themselves apart. And in the shadows, the Terran Marine Corps works to save what little they can to preserve civilization and build a better tomorrow. But now they might have met their match. 

Earth has fallen. The Core Worlds have collapsed into chaos. War is breaking out everywhere as planetary governments declare independence; entire sectors slip out of contact, and warlords battle for power. The remnants of the once-great Empire are tearing themselves apart. In the shadows, the Terran Marine Corps works to save what little they can to preserve civilization and build a better tomorrow. But powerful factions are competing with them, determined to establish their own order.

Prince Roland - the Childe Roland, Heir to the Imperial Throne - grew up in a gilded cage, surrounded by men who wanted to use his powers while keeping him under tight control. He was growing into a petty sadistic brat until a Marine Pathfinder took him in hand, helping him to overcome his caretakers - jailers - and make something of himself. But it was too late for Earth and, as the planet collapsed into chaos, Roland and his mentor barely escaped before it was too late. He was taken into the care of the Marine Corps and given a chance to go to Boot Camp and forge a new life.

Earth has fallen. The Empire is no more. Old certainties are collapsing everywhere. Chaos is spreading across the stars, with war following in its wake. Tarsus, a world too close to Earth for comfort, is far from immune. Clarence Esperanza, a reporter on Tarsus, thought he had the story of the century. But, when he took the story to his bosses, he was unceremoniously fired. Cut off from his former friends, abandoned by his wife isolated from the world around him, he thought all he could do was stagger onto the streets and wait to die. 

The Commonwealth has won a great victory, smashing Wolfbane's attempt to take Corinthian and driving Admiral Singh's forces back into enemy space. Now, as the Wolves reel under the impact of their defeat - and powerful factions plot to take control of the government and military - Edward Stalker plans a final offensive to bring the Wolves to their knees. But as mighty fleets clash in the inky darkness of space, infiltrators struggle to weaken a tottering edifice and both sides brace for the final confrontation, it all comes down to the last Terran Marines.

Despite the escape from Meridian - and a strike at the heart of Wolfbane - enemy forces are still advancing on all fronts. The Commonwealth, worn down by a year of hard fighting, is reaching the end of its tether while Admiral Singh, having secured control of Wolfbane, is searching for the breaking point that will shatter the Commonwealth once and for all. Time is needed, time to bring new weapons and tactics into service, but time is the one thing the Commonwealth doesn't have.

Arthur's Seat had never sought a galactic role. A relatively new colony world, a mere 300 years old, the planet was always isolated from the galactic mainstream. But with the Empire crumbling after the fall of Earth and other planets taking advantage of the chaos to make their own bids for power, Arthur's Seat suddenly finds itself playing host to tens of thousands of unwanted immigrants, refugees who have been kicked off countless other worlds.

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.  

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.

The war isn't going well. Wolfbane's forces are pressing the Commonwealth on multiple fronts, the Commonwealth's fragile political balance is on the verge of shattering, and there's a high-placed spy somewhere within the Commonwealth elite. For Colonel Edward Stalker and his men, the stakes have never been so high. Defeat will mean the end of everything they have fought and died for since their exile from Earth.

Earth has fallen - and humanity is holding its breath, waiting for the next blow to fall. On Terra Nova, Earth's oldest colony world, chaos and anarchy are threatening to break out, with total collapse only one disaster away. In a desperate attempt to save the rest of the Empire, the planet's Governor has summoned the leaders of the Core Worlds to Terra Nova, in hopes of sharing power and preventing civil war. But dark forces are on the move, intent on ensuring that the conference fails.

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. 

After the disastrous mission to Lakshmibai, the very existence of the Commonwealth is called into question by politicians on Avalon. But as the political firestorm mounts, a call for help arrives from Thule, a highly-developed world facing a major insurgency in the wake of the Empire's collapse. Reluctantly, the Commonwealth deploys the Commonwealth Expeditionary Force to Thule. But all is not as it seems.

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 Galactic Empire is dying. In their high towers, the Grand Senators plot and struggle to grasp a larger share of power while on the streets, the poor struggle to survive just one more day. Chaos and anarchy are running through the megacities of Earth, while giant corporations tighten the screws and colony worlds plot to declare independence and escape the Empire's increasing demands for resources. Centuries of mismanagement are finally catching up with the human race.
