The New York Times bestselling author of The Rose Code returns with an unforgettable World War II tale of a quiet bookworm who becomes history's deadliest female sniper. Based on a true story.

In 1937 in the snowbound city of Kyiv, wry and bookish history student Mila Pavlichenko organizes her life around her library job and her young son--but Hitler's invasion of Ukraine and Russia sends her on a different path. Given a rifle and sent to join the fight, Mila must forge herself from studious girl to deadly sniper--a lethal hunter of Nazis known as Lady Death. When news of her three hundredth kill makes her a national heroine, Mila finds herself torn from the bloody battlefields of the eastern front and sent to America on a goodwill tour.

Still reeling from war wounds and devastated by loss, Mila finds herself isolated and lonely in the glittering world of Washington, DC--until an unexpected friendship with First Lady Eleanor Roosevelt and an even more unexpected connection with a silent fellow sniper offer the possibility of happiness. But when an old enemy from Mila's past joins forces with a deadly new foe lurking in the shadows, Lady Death finds herself battling her own demons and enemy bullets in the deadliest duel of her life.

Based on a true story, The Diamond Eye is a haunting novel of heroism born of desperation, of a mother who became a soldier, of a woman who found her place in the world and changed the course of history forever.
