New York, 1924. Vivian Kelly's days are filled with drudgery, from the tenement lodging she shares with her sister to the dress shop where she sews for hours every day. But at night, she escapes to The Nightingale, an underground dance hall where illegal liquor flows and the band plays the Charleston with reckless excitement. With a bartender willing to slip her a free glass of champagne and friends who know the owner, Vivian can lose herself in the music. No one asks where she came from or how much money she has. No one bats an eye if she flirts with men or women as long as she can keep up on the dance floor. At The Nightingale, Vivian forgets the dangers of Prohibition-era New York and finds a place that feels like home. But then she discovers a body behind the club, and those dangers come knocking. Caught in a police raid at the Nightingale, Vivian discovers that the dead man wasn't the nameless bootlegger he first appeared. With too many people assuming she knows more about the crime than she does, Vivian finds herself caught between the dangers of New York's underground and the world of the city's wealthy and careless, where money can hide any sin and the lives of the poor are considered disposable...including Vivian's own.
