New York City, 1998: When Ella Gilbert discovers her banker husband is cheating on her, she loses both her marriage and the life she knew. In her new apartment in an old Greenwich Village building, she's found unexpected second love with Hector, a musician who lives upstairs. And she's discovered something else, just as surprising—a connection to the mesmerizing woman scandalously posed in a vintage photograph titled Redhead Beside Herself. Florida, 1924: Geneva "Gin" Kelly, a smart-mouthed flapper from Appalachia, barely survived a run-in with her notorious bootlegger stepfather. She and Oliver Anson, a Prohibition agent she has inconveniently fallen in love with, take shelter in Cocoa Beach, a rum-running haven. But the turmoil she tried to leave behind won't be so easily outrun. Anson's mother, the formidable Mrs. Marshall, descends on Florida with a proposition that propels Gin back to the family's opulent New York home, and into a reluctant alliance. Then Anson disappears during an investigation, and Gin must use all her guile and courage to find him. Two very different women, separated by decades. Yet as Ella tries to free herself from her ex, she is also hunting down the truth about the captivating, wicked Redhead in her photograph—a woman who loved and lived fearlessly. And as their link grows, she feels Gin urging her on, daring her to forge her own path, wherever it leads.
