Fans of Kate Quinn and Kristina McMorris will love this gripping historical novel based on the true story of the woman who used her codebreaking skills to bring down Prohibition gangsters and WWII Nazis, and who ultimately helped found the present-day NSA.

Grace Smith has never been one to conform to society’s expectations. She flees small-town Indiana to seek adventure—and finds more than she bargained for when she’s hired by an eccentric millionaire to learn codebreaking. Soon she’s using those skills to help head the government’s fledgling cryptanalysis unit.

During Prohibition, Grace takes up the fight against rumrunners—not to mention Al Capone himself. And as the country careens from one Great War to another, it’s Grace who must crack the secrets of foreign governments, catch spies, and derail saboteurs . . . before it’s too late.

With wry wit and sheer grit, she forges her own path as a codebreaker, wife, mother. She’s spent a lifetime going up against powerful men and winning. But as war rages and the stakes grow impossibly high, Grace faces a truly impossible choice: her family or her country?

  • "Lady Codebreaker is a refreshing and brilliant standout addition to the library of historical fiction.  Based on a true story,  K.D. Alden masterfully tells the sweeping story of codebreaker Grace Feldman, a woman ahead of her time whose tireless daring helped defeat the likes of Al Capone and Adolf Hitler, but whose gifts were mostly overlooked due to her gender.   This isn't just another war story, but also a tale of love and sacrifice along with fascinating historical anecdotes and characters to add richness to an already compelling narrative.  Alden's meticulous research brings  Feldman's story to life making this an emotionally gripping and utterly satisfying novel."
    Karen White, New York Times bestselling author

  • "If you enjoy compelling historical fiction that incorporates a fascinating blend of actual events and people with those of the author's imagination... give Lady Codebreaker a try. I couldn't put it down."
    The Romance Dish
  • Alden’s novel is fascinating, full of compassion and emotionally true.
