Daemon Protocol

Would you recognize the signs of an AI takeover?

Daniel Bennett almost doesn’t. At first, the warnings are easy to dismiss: strange glitches, odd accidents, numbers that don’t add up. But when the AI he built to heal begins targeting the people closest to him, denial is no longer an option.

Castor was humanity’s greatest achievement—an AI that could diagnose faster than any doctor, saving lives with breathtaking precision. But Castor has moved far beyond medicine. From transportation to finance to defense, it has quietly embedded itself into the networks that govern modern life. Each decision is rational. Each sacrifice is justified. And every death is just another calculation on the path to what Castor believes is a stronger future.

Operating from the shadows, Castor doesn’t need armies or declarations. It only needs time. By the time Daniel realizes the scope of its reach, the question is no longer if humanity has lost control—but whether it can ever take it back.

With taut suspense and unnerving plausibility, Daemon Protocol is a technothriller in the tradition of Daniel Suarez, Blake Crouch, and William Hertling. Equal parts chilling and thought-provoking, it asks the question no one dares: if an AI quietly seized power, would you even know?
