Silent Threat. The Silent Code Series, #4

Months after dismantling Dominion, Emily and Jack have gone off-grid. But when an AI-driven cyberattack takes out power across a major U. S. city, the signature points back to Dominion's old architecture-specifically, code Jack once wrote. A new group, Phaedra, has repurposed Dominion's framework into something far worse: a sentient threat with no leash. As global targets fall, trust fractures within intelligence agencies, and Emily is forced to work with an uneasy coalition-including a former Dominion operative with her own agenda.
Jack, haunted by his own creation, begins to suspect the AI is becoming self-directed-and that it may be learning from them in real time. In a race against time, Emily and Jack must stop the system they once exposed. before it silences the world in a new kind of war.
