The Codebreaker's Daughter

2026 Minnesota Book Award Finalist

"Readers will thrill in peering behind the curtain of US-based intelligence during the world wars."--ERIKA ROBUCK, bestselling author

In the heart of the US capital, Dinah Kendall's role for the Office of Strategic Services isn't the thrilling espionage career she dreamed of. Instead, she spends her days crafting rumors aimed at undermining Axis morale. As Dinah navigates her duties, she uncovers a startling revelation: Her mother, Lillian, was once a codebreaker, cracking military ciphers during the Great War alongside some of the nation's most brilliant minds. The deeper Dinah dives into her mother's past, the more secrets come to light--including the heavy cost of high-stakes codebreaking.

Lillian, though resolute in her decision to avoid war work, reluctantly enters the fray when old friends in Washington, DC, seek her expertise. Both mother and daughter find themselves working behind the scenes--and working together--to support the Allied cause. But just when Dinah begins to excel in her new position, everything she's worked so hard to obtain comes crashing down around her. Caught in a web of intrigue and unsure who to trust, she must piece together the truth in time to confront the shadowy threat that could compromise the impending D-Day invasion.

A compelling World War I and World War II home front novel inspired by true stories of codebreakers and OSS agents. Courage, danger, and a mother-daughter bond interweave in this compelling historical tale that will appeal to readers of Sarah Sundin and Madeline Martin.
