"A fact-based historical novel, as compelling as Nancy Horan's New York Times bestseller, Loving Frank, set primarily in New York City in the 1920s and '30s and inspired by the decade-long relationship between the celebrated composer George Gershwin and Kay Swift, who was both his romantic partner and a gifted musician in her own right"-- Provided by publisher.

1924. Katharine "Kay" Swift, restless but loyal society wife of wealthy banker James Warburg and a serious pianist who longs for recognition, attends a concert. The piece: Rhapsody in Blue. The composer: a brilliant, elusive young musical genius named George Gershwin. Unable to resist the magnetic pull of George's talent, charm, and swagger, Kay embarks on a ten-year love affair with him. Her life is complicated by her conflicted loyalty to her husband and the twists and turns of her own musical career. The affair ends only with George's death from a brain tumor at the age of thirty-eight. -- adapted from jacket.
