Two years ago, Lieutenant Commander Roslyn Chambers stood witness to the surrender of the last remnants of the Republic. Fueled by atrocity against Mage and mundane alike, the secessionists who waged war against the Protectorate of Mars are finally defeated. Now, a special commission from the Mage-Queen of Mars takes Roslyn deep into the former Republic to hunt the architects of that atrocity. Mages who betrayed their own, the creators of Project Prometheus must be brought to justice. But hidden from even the Republic, Prometheus has woven magic and technology together once more.

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.

Morgan Casimir, commander of the A!Tol Imperial cruiser Defiant, has seen the works of the Precursor aliens known as the Alava. She has seen their accidents threaten worlds and consume entire star fleets. Charged by her empress to prevent a conspiracy of profiteers from finding and using a lost fleet of Alava warships, she knows unimaginable catastrophe looms if she fails. With her lover, xenoarcheologist Dr. Rin Dunst, at her side, she is sent to a hot zone on the edge of war to once again achieve the impossible. 

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.

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.

Earth is conquered. Sol is lost. One ship is tasked to free them. One Captain to save them all. When an alien armada destroys the United Earth Space Force and takes control of the human homeworld, newly reinstated Captain Annette Bond must take her experimental hyperspace cruiser Tornado into exile as Terra's only interstellar privateer. She has inferior technology, crude maps, and no concept of her enemy, but the seedy underbelly of galactic society welcomes her so long as she has prizes to sell and money to spend.

For 17 years, Colonel Henry Wong and the United Planets Space Force have fought the Kenmiri Empire. They drove the alien overlords back from humanity's borders into their own stars and found allies among the Kenmiri's slaves and subjects. Now the war is over. A great Gathering has been called of the allies who fought the war, but they only ever shared a common enemy. With the Kenmiri in retreat, a thousand new agendas are revealed.

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.

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.

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.
