The empire of Carthage rules the galaxy with AI-controlled warships and ruthless robotic armies. Rebellion brews on the fringes of settled space, seemingly in vain. The robots' sights are set on ocean world Galapagos, governed by a battle-hardened submarine commander determined to uphold his planet's fragile peace. In the ruins of Chicago, a determined scavenger discovers something that could challenge the might of the machines, but could also endanger everyone he loves. Scouring Carthage's underworld in search of her missing brother, imperial heiress Audrey Caracala must confront her family's blood-soaked legacy. Three worlds. Three heroes. One enemy programmed for victory at any cost.
