A brilliant code breaker shatters a centuries-old conspiracy and unravels her own family secrets in an addictive and heart-pounding thriller by Edgar Award–nominated author Jess Lourey.

Salem Wiley is a genius cryptanalyst. She’s also a loner who prefers a safe and familiar path. Until her mother disappears in the wake of a brutal murder, leaving behind a cryptic warning of threats to come. Forced out of her safe zone, Salem embarks with her best friend, Bel, on a dangerous quest that reaches back centuries into America’s hidden history.

Drawn into a labyrinth of messages encrypted by Emily Dickinson and hidden in the legendary Beale Cipher, Salem discovers her mother’s double life—and the truth. An ancient and ruthless society is hell-bent on ruling the world, and only a select group of hunted women stands in its way.

Now Salem must follow a cross-country trail of clues in a desperate bid to unravel the conspiracy, which threatens not only the present but the very course of history.
