New York Times bestselling author Karen Abbott tells the spellbinding true story of four women who risked everything during the Civil War.

Seventeen-year-old Belle Boyd, an avowed rebel with a dangerous temper, shot a Union soldier in her home, and became a courier and spy for the Confederate army, using her considerable charms to seduce men on both sides. Emma Edmonds disguised herself as a man to enlist as a Union private named Frank Thompson, witnessing the bloodiest battles of the war and infiltrating enemy lines. The beautiful widow Rose O'Neal Greenhow engaged in affairs with powerful Northern politicians and used her young daughter to send information to Southern generals. Elizabeth Van Lew, a wealthy Richmond abolitionist, hid behind her proper Southern manners as she orchestrated a far-reaching espionage ring—even placing a former slave inside the Confederate White House—right under the noses of increasingly suspicious rebel detectives.

With a cast of real-life characters, including Nathaniel Hawthorne, General Stonewall Jackson, Detective Allan Pinkerton, Abraham and Mary Todd Lincoln, and Emperor Napoléon III, Liar, Temptress, Soldier, Spy shines a dramatic new light on these daring—and, until now, unsung—heroines.
