Inside a dystopian school in the Singularity, the 12-year-old girl known as One Twenty-Four struggles to survive. Failure to conform means death at the hands of her teacher. Assuming her clone sisters don't kill her first. The Terran Empire has tasked Imperial Marine Lieutenant Grace Tolliver to lead her platoon into the Singularity as a privateer. Her mission: to tear a great bloody strip off their enemies and to take anything that isn't nailed down. The collision of this unlikely pair will change the humanity in ways that no one could predict. If they survive.

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.

After years of battle, Kelsey Bandar and Jared Mertz are finally ready to face the master AI enslaving the Terran Empire. With just a bit of luck, this nightmare will finally be over. Only luck can run out just when you need it the most. Outnumbered and outgunned, they must salvage victory from certain defeat. Failure means extermination, invasion, and the loss of everyone they love. Can they beat the odds just one more time? 

Kelsey Bandar and Jared Mertz must retrieve the electronic override buried under the ruins of the old Imperial Palace to win the war against the AIs. Oh, and get off the planet in spite of the murderous warships orbiting the destroyed world. How hard could that be? Imprisoned in a dead megacity and surrounded by howling savages thirsty for their blood, they must triumph or die. And if they die, humanity dies with them.

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.
