Virtuoso pianist Isabette Greuber captivates audiences in the salons and concert halls of early nineteenth-century Vienna. Yet in a profession dominated by men, Isabette longs to compose and play her own music--a secret she keeps from both her lascivious manager and her resentful mother. She meets and loves Amelia Mason, a dazzling American singer with her own secrets, and Josef Hauser, an ambitious young composer. But even they cannot fully comprehend the depths of Isabette's talent. Her ambitions come with a price when Isabette embarks on a journey that delicately walks the line between duty and passion. Amid heartbreak and sacrifice, music remains her one constant.
