Ginger Kelly wakes up in 1924 in tranquil Cocoa Beach, Florida, after fleeing to safety with disgraced Prohibition agent Oliver Anson Marshall, and her newly-orphaned young sister, Patsy. But Marshall is reinstated to the agency with suspicious haste to patrol for rumrunners on the high seas. When he promptly disappears, Gin hurries north to rescue him, only to be trapped in an agonizing moral quandary by Marshall's desperate mother. In 1998, Ella Dommerich is settled into her new life in Greenwich Village, inside the same apartment where a certain redheaded flapper lived long ago. Having quit her job at an accounting firm, cut ties with her unfaithful ex-husband, and begun a love affair with her musician neighbor, Hector, Ella's eager to piece together the history of the mysterious Gin Kelly, whose only physical trace is a series of rare vintage photograph cards for which she modeled before her disappearance. Two women, two generations, and two urgent quests will require both women's strength and determination to outwit a conspiracy spanning decades.
