It started with a DNA test. A lark. A curiosity. An impulse Rachel Danner was talked into submitting by her co-workers.

But when the results arrive, they shatter everything she knows about her life. She was not adopted at birth, as her records claimed; she was taken in at six years old. And her biological parents? Evelyn Ashcroft and Robert Klein. Names sealed by time, buried by scandal... and etched into the annals of criminal history as two of the most infamous serial killers the state has ever known.

As Rachel digs deeper into her past, the fragile façade of her carefully constructed identity begins to fracture. A detective with secrets of her own reopens a cold case, and together they uncover a legacy of psychological conditioning, ritualistic trauma, and something far more disturbing than any murder: a design. A system. A blueprint for control.

But the deeper Rachel goes, the more impossible truths emerge; about who she is, what she was meant to become, and the twin sister she never knew existed.

Some inherit trauma. Rachel inherited a pattern. And it's still unfolding.
