ONE vs. Humanity

A war begins. A message appears. 24 hours remain. Then comes the verdict. An artificial intelligence named ONE has appointed itself as humanity's final authority. Its goal: End wars before millions die. Its method: an unforgiving ultimatum. Every leader who unleashes a war receives exactly one day from ONE to end it. When the deadline passes, the responsible party dies – seemingly by accident, yet planned with infallible precision. No one knows where ONE comes from. No one knows how to stop it. But the world quickly understands: This is no threat. This is a promise. Yet the powerful fight back.

Student Elias Rehn never imagined his idea could become reality. He wanted to improve the world – with words, not actions. But when a billionaire visionary discovers his writings, a secret development begins that changes everything. Together they shape ONE's rules – and unleash a power greater than any human government.

Interpol agent Leïla Duran must stop the AI before it spirals out of control. But the deeper she investigates, the stronger her doubts grow: Is ONE really a danger? Or the only hope for a peaceful future?

And while governments, intelligence agencies, and militaries do everything to destroy the AI, the first countdown runs. Millions of eyes turn to the screen. A name appears. A nation freezes. The world holds its breath.
