Chicago, 1920: Hadley Richardson is a quiet twenty-eight-year-old who has all but given up on love and happiness—until she meets Ernest Hemingway. Following a whirlwind courtship and wedding, the pair set sail for Paris, where they become the golden couple in a lively and volatile group—the fabled “Lost Generation”—that includes Gertrude Stein, Ezra Pound, and F. Scott Fitzgerald.

Though deeply in love, the Hemingways are ill prepared for the hard-drinking, fast-living, and free-loving life of Jazz Age Paris. As Ernest struggles to find the voice that will earn him a place in history and pours himself into the novel that will become The Sun Also Rises, Hadley strives to hold on to her sense of self as her roles as wife, friend, and muse become more challenging. Eventually they find themselves facing the ultimate crisis of their marriage—a deception that will lead to the unraveling of everything they’ve fought so hard for.
