Italy, 1905. Fourteen-year-old Lucia and her young mother, Teresa, are servants in a magnificent villa on the Bay of Naples, where Teresa soothes their unhappy mistress with song. But volatile tempers force them to flee, exchanging their warm, gilded cage for the cold winds off Lake Erie and Cleveland's restless immigrant quarters.

With a voice as soaring and varied as her moods, Teresa transforms herself into the Naples Nightingale on the vaudeville circuit. Clever and hardworking, Lucia blossoms in school until her mother's demons return, fracturing Lucia's dreams.

Yet Lucia is not alone in her struggle for a better life. All around her, friends and neighbors, new Americans, are demanding decent wages and working conditions. Lucia joins their battle, confronting risks and opportunities that will transform her and her world in ways she never imagined.
