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.

The A!Tol Imperium and their new human subjects have had 15 years of relative peace. New colonies have been founded, new worlds explored, new ships built. Formal and informal alliances have been built with the ancient powers of the Core, leaving humanity and the Imperium seemingly on the brink of a new dawn. The devastation of one of the newly-founded human colonies sends ripples of shock through the Imperium, and a battle fleet under Fleet Lord Harriet Tanaka is dispatched to the edge of the Imperium to find the culprits and bring them to justice.

Humanity's first colony is a project neither the Duchy of Terra nor the A!Tol Imperium can allow to fail. The planet Hope in the Alpha Centauri system has been lavished with resources and attention - but when an unknown alien force attacks the system, all of that is in danger. An ancient alien artifact is the apparent target of the attack, an artifact older than known galactic civilization. Suddenly, the backwater colony of a second-rate power is the gathering point for a confrontation of the galaxy's greatest powers.

When Terra knelt to an alien Imperium, they guaranteed our safety and our future. But now their enemies are coming for us. To preserve humanity's survival and freedom in a hostile galaxy, Annette Bond tied her world to the A!Tol Imperium, taking on the mantle of Duchess of Terra to rule humanity in the Imperium's name. The A!Tol have provided technology, ships, and money to uplift the new Duchy of Terra, but those gifts come with strings attached. The Imperium has their own plan for Terra - but Bond has tricks of her own.

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.

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. 

Captain Morgan Casimir’s mission to stop a war has ended in a nightmare. In the heart of an ignored nebula, trapped behind a ring of newborn stars, she has awoken a creature of another time: the horde of biological starships who call themselves the Infinite. Fifty thousand years ago, the Infinite drove the galaxy’s Alavan Precursors to a grave mistake that destroyed all that was. Unleashed once more by the very people Morgan Casimir sought to stop, the Infinite now threaten an entirely new era. 

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.

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.
