From the bestselling author of The Quarry Girls comes this breakneck thriller about a troubled codebreaker who faces an epic plot reaching back through centuries of America’s secret history.

★ "...[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 her quantum computing breakthrough. She's also an agoraphobe shackled to a narrow routine since her father's suicide. When her intelligence work unexpectedly exposes a sinister plot to assassinate the country's first viable female presidential candidate, Salem finds herself both target and detective in a modern day witch hunt.

Drawn into a labyrinth of messages encrypted by Emily Dickinson and codes tucked inside the Beale Cipher a hundred years earlier, 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.

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