Salem Wiley is a genius cryptanalyst, courted by the world’s top security agencies ever since making a quantum computing breakthrough. She’s also an agoraphobe who’s afraid to leave her house. When her mother’s disappearance is linked to a plot to assassinate the country’s first viable female presidential candidate, she’s forced out of her safe zone.
Drawn into a labyrinth of messages encrypted by Emily Dickinson and century-old codes tucked inside the Beale Cipher, Salem begins to uncover the truth: an ancient and ruthless group is hell-bent on ruling the world, and only a select group of women stands in its way.
