★ "...[A] hair-raising thrill ride." ―Library Journal (starred review) 

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. 

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.

★ "A fast-paced, sometimes brutal thriller reminiscent of Dan Brown's The Da Vinci Code."―Booklist (starred review)

Salem's Cipher is the first in an ongoing series of heart-pounding thrillers that international bestselling author Lee Child calls "highly recommended!"
