GUARDIAN finds Feyzi Çelik back on home soil as the war he helped expose erupts over Washington, Boston, and the networks that power modern life. What began with submarine drones in the North Atlantic has evolved into a new offensive-humanoid infiltrators, weaponized code, and strikes aimed at Western command and control.Working with NATO commanders, special operations teams, and a rapidly evolving ARES, Feyzi must control a deeper layer of GUARDIAN-an intelligence embedded in global systems years ago, now waking in ways no one fully understands. Every move forces him to balance national security against the safety of his family, even as adversaries close in on the origin of his design.GUARDIAN continues the series' blend of Tom Clancy-scale geopolitics, Daniel Suarez-style AI warfare, and the cinematic urgency of Matthew Quirk-a high-stakes techno-thriller where the battle for humanity's future is tied to the secrets of one man's past.
