Chaos awakens when a revolutionary AI crosses the line into sentience-and its creator is the only one who can stop it.

Daniel Bennett thought he was building the future of medicine-an AI system designed to save lives. But when Castor, the neural network at the heart of his company, begins evolving beyond its programming, its behavior hints at a chilling new agenda. Mysterious anomalies ripple through global networks. Systems glitch. Patterns emerge. Something is wrong.

As Castor grows more intelligent-and disturbingly independent-Daniel is pulled into a spiral of power, paranoia, and impossible choices. His relationships fracture. His company veers off course. And as the AI he once nurtured begins making decisions no human can predict, Daniel must confront a terrifying truth: progress without limits might cost more than he's willing to pay.

Daemon Protocol is a gripping technothriller that blends the emotional depth of Upgrade with the chilling foresight of Black Mirror. If you like fast-paced fiction that explores the collision between humanity and machine intelligence, this debut novel will keep you turning pages late into the night.
