In a world where memories can be rewritten and people erased without a trace, one teacher becomes the key to unlocking the truth.

Madeleine Hart lives an ordinary life—grading papers, mentoring students, and maintaining her calm in a society ruled by an all-seeing artificial intelligence designed to predict and prevent crimes. But when the system suddenly identifies her as a potential killer, everything changes. The surprise? The supposed "victim" she's accused of targeting doesn't exist.

Hounded by a name no one else remembers, and pursued by forces determined to silence her, Madeleine uncovers a terrifying secret: a secret program that erases people from existence—not just their lives, but their entire identities. As she delves deeper into the data-driven machinery of her world, she encounters the Echo Network, a group of rogue technologists fighting to reclaim what was lost.

With every step, the line between truth and fabrication blurs. Madeleine must risk everything to expose a cover-up that reaches the highest levels of power and answer the most dangerous question of all: Who decides who we remember and who we don't?
