Unfettered Folds

Commodore Archer Devereaux has already changed the face of the war for the Orion Spur, but the fight is far from over.

With the discovery of the Defender and its god-like AI, Vanguard, the Phlegraean Alliance and the Economic Union finally have a weapon the enemy can’t see coming: the skladka fold, a technology that makes every system in the galaxy a neighbor—and a target.

Now leading the elite Rapid Deployment Force (RDF), Archer must execute a series of daring, "blink-and-you’ll-miss-it" surgical strikes to shred enemy battle groups before they can unite their overwhelming numbers.

But as the allies move to merge into the Orion Accord, the enemy is desperate to bridge the technological gap at any cost.

When the Federation’s attempt to clone Archer's technology results in Indomitable, a rogue AI that views humanity as a fragile hindrance, the war becomes an existential battle for survival.

With systems failing and the enemy’s own creations turning against them, Archer and operative Bette Matteson must navigate a maze of sabotage, political upheaval, and sentient machines that don’t know how to lose.

Experience the sixth installment of the Orion Spur series, a military science fiction epic where ancient AI secrets and cutting-edge tactics decide the fate of humanity.
