In the snowbound city of Kiev, wry and bookish history student Mila Pavlichenko organizes her life around her library job and her young son, but Hitler's invasion of 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.
