The Algorithm's Shadow

Leah Mendez is a data scientist who reads numbers the way other people read faces. Working late in an empty office, she finds a minor anomaly in a routine dataset. She flags it. She moves on.

She should have left it alone.

What Leah has found is the edge of the Substrate Program: a federal operation that doesn't arrest people, doesn't surveil them, doesn't touch them. It simply erases them. Quietly, bureaucratically, completely. No detention. No record. Just the slow removal of every administrative trace that proves a person exists.

When the program turns its machinery on Leah, she loses everything: her job, her accounts, her identity. On paper, she is dead. In practice, she is invisible. And invisible, she discovers, is the only thing the program cannot account for.

Working from the outside with an investigative journalist, a detective who has been carrying an unsolved case for eleven years, and a shadow ally she has never met, Leah builds the evidence that could expose the program. But the closer she gets to the truth, the more she understands: this is not a corporate conspiracy. It goes deeper than that. It always has.

The Algorithm's Shadow is a literary thriller about data, power, and what it costs a system to make a person disappear.
