A dying world, shattered by a broken machine. A desperate flight, their only hope for refuge. A robotic race, ally and destroyer alike. The Republic of Exilium has grown in strength and confidence at the far end of the galaxy from the rest of mankind, sending out scout ships to survey the worlds around them as they try to learn more about the mysterious Construction Matrix AIs. Finding one of the genocidal rogues of that mysterious “race” in the process of destroying an inhabited world, Captain Octavio Catalan takes his ship into a desperate battle.

Seeking to escape the shadow of Annette Bond’s success, Captain Morgan Casimir has taken a posting on the far side of the A!Tol Imperium. Here she hopes to begin a legend for herself that stands apart from her stepmother, the Duchess. A chance encounter introduces her to the xenoarchaeologist Rin Dunst - and to the strange mystery cult that tried to silence him. There are darker secrets in these stars than the A!Tol and their human allies ever guessed...and if they can’t find answers, the Precursors' mistakes might yet destroy the galaxy. Again.

The Kenmiri Empire has fallen, broken against the might of the Vesheron rebels and the United Planets Space Force. The alliance between the Vesheron and the UPSF has collapsed in turn, leaving the former empire as worlds without governance or leaders. Amidst the chaos, the UPSF has launched a valiant effort to reach out to the weak and protect the defenseless. As part of the Peacekeeper Initiative, Colonel Henry Wong leads the battlecruiser Raven deep into once-hostile territory. There, an old ally has begun to forge a new empire from the old slave worlds.

Kira Demirci left her homeworld of Apollo, pursued by assassins, seeking revenge for her victories in the war against the Brisingr Kaiserreich. She now has a new home and a new role as the nova fighter wing commander aboard the mercenary carrier Conviction under Captain John Estanza. Conviction is on retainer with the royal family of Redward, which encourages Kira and her pilots to make themselves a new home on the frontier planet. But there is a reason they want to tie the mercenary carrier’s crew more tightly to themselves, and storm clouds are brewing on the horizon.

Isaac Gallant is the heir apparent to the First Admiral. Unwilling to let his mother’s tyranny stand, he joins the rebellion and leads his ships into war against the might of his own nation. Betrayal and failure, however, see Isaac Gallant and his allies captured. Rather than execute her only son, the First Admiral instead decides to exile them, flinging four million dissidents and rebels through a one-shot wormhole to the other end of the galaxy. There, Isaac finds himself forced to keep order and peace as they seek out a new home without becoming the very dictator he fought against.

The last reward Kira Demirci expected for heroism in a time of war was to spend the rest of her life dodging assassins - but when her government betrays her as part of their surrender, she and her comrades flee the star system of Apollo to the edge of civilized space. The Syntactic Cluster is disorganized, disunified, and in desperate need of the nova fighters Kira smuggled out of Apollo with her. With an entire squadron supposed to follow in her wake, it falls to her to build a new home for her comrades.

Secrets and warships combined to turn the tide of the Siege of Legatus, delivering the capital of the Republic of Faith and Reason into the hands of their enemies. With Damien Montgomery called away to lead the entire Protectorate of Mars, fighting the war falls to Mage-Admiral Jane Alexander and Mage-Lieutenant Roslyn Chambers. As the Martian Second Fleet moves against the remaining Republic worlds, Captain Kelly LaMonte’s covert stealth ship sweeps the worlds away from the conflict, searching for the Republic’s government-in-hiding and a chance to end the bloody conflict.

As the celebration of the victory at Legatus cools, a shuttle accident claims the lives of the Mage-King of Mars and his heir. The Crown and the Mountain fall to the Mage-King’s daughter, 16-year-old Kiera Alexander. She recalls Damien Montgomery, her father’s First Hand, to stand as her Lord Regent. The pair are unprepared to govern but are thrust into the heart of Protectorate politics. Damien is grimly certain of one thing: when it comes to the deaths of Kings, he doesn’t believe in accidents.

When the Taljzi’s genocidal invasion brought promises of aid from the oldest and greatest of the Core Powers, humanity and the Imperium looked to the Mesharom for salvation. But that salvation turns to ash as the Mesharom demand the surrender of the very weapons that saved the Imperium. Defiance leaves the Imperium facing the Taljzi without the aide of the galaxy’s wisest race, but with their old enemies the Kanzi at their side, they have no choice but to end this war at any cost.

A dozen inhabited worlds of the Kanzi Theocracy and the A!Tol Imperium are ash. Millions of sentients of a dozen species are dead, including humans from the brand-new colonies built under the Imperium's watch. Despite the losses, the strange Taljzi fanatics have been defeated - but everything suggests that more will be coming. The Empress of the A!Tol has resolved that the cold war between A!Tol and Kanzi must end. She sends Duchess Annette Bond to the heart of the Kanzi Theocracy to negotiate a new alliance.

When a minor trade partner sends the Castle Federation a desperate call for aid, they have few resources to spare from their all-consuming war against the Terran Commonwealth. Unwilling to be seen failing their allies but able to spare only a tiny force, Castle sends a hero to command the task group: Captain Kyle Roberts, the Stellar Fox. Beyond the Rimward frontier of the Federation and its allies, little is as it seems. The pirates are being armed by an outside force, and the politics of these worlds is made deadlier by their poverty.

For two years, the Castle Federation and the Alliance of Free Stars have stood against Marshal James Walkingstick of the Terran Commonwealth and his mission of conquest. Battles have been won and lost, worlds have died, and soldiers like Admiral Kyle Roberts have been forged on the anvil of war. But the Alliance cannot win. The Commonwealth has more worlds, more ships, more soldiers. They claim their victory is inevitable. That history is on their side. Refusing to accept the Commonwealth's future, the Alliance embarks on a do-or-die mission to end the war in one strike.

Marooned on ruined Terra, Kelsey Bandar and Jared Mertz must march to the Imperial Palace to recover the key to defeating the savage AIs that have enslaved humanity. If, of course, the fierce and primitive Terrans don’t kill them first. Trapped without their advanced technology, they must overcome foes determined to take everything they have left, including their very lives. If they don’t find allies fast, humanity is doomed.

The Terran Commonwealth has proved a nigh-unstoppable juggernaut in its war against the smaller Castle Federation and her allies, but an almost accidental victory by Captain Kyle Roberts of the carrier Avalon has opened a chink in its armor. Desperate to change the course of a war they are rapidly losing, the Federation assembles a new forward fleet with orders to retake the systems that have fallen to the enemy.

Captain Kyle Roberts delivered one of the Castle Federation's few victories in the early days of the war. Even losing his ship in the process didn't prevent him from being elevated as the hero - the "Stellar Fox" - his country desperately needed. His status with the public demands a worthy command, and he finds himself on the bridge of the federation's latest supercarrier and headed to the front lines of the war. But the navy sees his promotion as a public relations stunt.
