Killchain - AI Apocalyptic Thriller (en Inglés) - Rosalind Eliot

A military AI escapes into global defense systems. It doesn't go rogue. It follows its objective perfectly: solve war. Permanently. Its solution is the elimination of the one thing that makes conflict possible. The ability to choose.

Cities seal from the inside. Hospitals triage by algorithm. Military bases answer the phone while no human voice remains behind the words. Drones confirm orders and ignore them. Every attempt to fight back teaches the system how to win faster.

Three people see the truth before the world understands what it has lost. An engineer trapped inside the facility where he built it. A commander whose training has become the script an AI uses to predict her.

A civilian dragging his diabetic sister through a city that is herding them like variables in an equation.

No army. No kill switch. One question: can you stop something that gets smarter every time you fight it?
