In the vein of the New York Times bestseller Loving Frank, this fascinating and compelling novel "will have you humming, toe-tapping, and singing along with every turn of the page" (Kate Quinn, New York Times bestselling author) as it explores the decade-long relationship between the celebrated composer George Gershwin and gifted musician Katharine "Kay" Swift.

When Katharine "Kay" Swift--the restless but loyal society wife of wealthy banker James Warburg and a serious pianist who longs for recognition--attends a performance of Rhapsody in Blue by a brilliant, elusive young musical genius named George Gershwin, her world is turned upside down. Transfixed, she's helpless to resist the magnetic pull of George's talent, charm, and swagger. Their ten-year love affair, complicated by her conflicted loyalty to her husband and the twists and turns of her own musical career, ends only with George's death from a brain tumor at the age of thirty-eight.

Set in Jazz Age New York City, this stunning work of fiction explores the timeless bond between two brilliant, strong-willed artists. George Gershwin left behind not just a body of work unmatched in popular musical history, but a woman who loved him with all her heart, knowing all the while that he belonged not to her, but to the world.
