After she remembers a mass-casualty bombing before it happens, a trauma cleaner discovers her estranged father built a secret system that can edit human memory-and now he plans to use it to make an entire country believe a lie worth killing for.

Nina Solis cleans up blood for a living.

It is the one job that makes sense after her mother's death and her father's disappearance into a classified world that swallowed him whole. Bodies are honest. Grief is honest. Memory is not.

When Nina suffers a violent flash of a subway bombing minutes before it happens, she thinks she is breaking. Then armed men try to take her alive.

The attack was real. So was the memory. And Nina is not the only one who saw it.

Buried inside a black program called the Memory Index is a technology capable of recording, altering, and planting memory so deeply the victim will die defending it as truth. The architect of that system is Dr. Elias Voss-Nina's father. Officially, he vanished years ago. Unofficially, he is preparing the largest cognitive attack in modern history: a manufactured atrocity that will redraw elections, borders, and loyalties in a single week.

Hunted across a city where any witness can be rewritten and any ally can wake up as an enemy, Nina must decide whether to save the man who ruined her life or destroy the only person who knows how to stop what he built.

Because if memory can be weaponized, innocence is over.
