In a summer heatwave, Dallas goes dark. Hospitals lose power, air traffic controllers go blind, and the grid's heartbeat flatlines. What looks like a nation-state cyberstrike is, in fact, something worse: a precision campaign by Aegis Global Defense-an ultra-privatized security conglomerate that sells "stability" the way cartels sell product. Ex-special operations officer Ethan Stroud is dragged back into the fight, pairing with Lila Chen, a contract analyst whose code can peel secrets out of fortified servers. From Texas substations to D.C.'s Union Station, from Congolese lithium pits to a seaborne command fortress, they unravel Project Dominion-a blueprint to replace democratic resilience with pay-to-play sovereignty. As Aegis orchestrates staged blackouts, false-flag "drills," and boardroom coups, Ethan and Lila assemble a counteroffensive that runs on two fuels: exposure and precision. They weaponize evidence while waging close-quarters battles in tunnels, highways, jungles, and steel corridors. Their war becomes a ledger: each action must degrade capability without becoming the story their enemies want. When Aegis CEO Victor Kade unveils a rentable sky of AI-driven drones, Ethan seizes the uplink and turns the swarm against its masters, forcing the market-and the world-to watch. Dominion doesn't just fall; it implodes under the weight of subpoenas, frozen accounts, and truth made public. This is a high-tension, gear-true techno-thriller with the moral knuckle and the geopolitical circuitry of suppressed carbines in echoing corridors, HALO insertions over black water, thermite on convoy axles, and a chess match played across legal, financial, and digital boards. Iron Dominion asks a blunt question: if sovereignty can be privatized, who fights for the public square when the bill comes due?
