In a world where an AI system called Eidolon has eliminated heartbreak matching four hundred million people with mathematical precision data analyst Lena Maro trusts the algorithm completely. Until it matches her with Kai Voss at a 97.3% compatibility score, and she glimpses three seconds of hidden text: a 92.4% probability that he will be responsible for her death.

What begins as a private investigation spirals into the discovery of a twenty-year conspiracy. The algorithm doesn't just predict love it harvests the most intimate data humanity has ever voluntarily surrendered, licensing it to a shadowy consortium that uses the matching system to silence anyone who gets too close to the truth. Eleven women have already died. And Lena's mother, who built the original mathematics, was the first.

Forced into proximity with the man flagged to destroy her, Lena must decide what the numbers actually mean and whether the system warning her is the same system that built her, that stole from her mother, and that is now, perhaps, trying to save her.

The Algorithm Chose You is a novel about power, mathematics, grief, and the only prediction no algorithm can make: the moment a person chooses truth over safety.
