After her lover--a famous conductor--dies unexpectedly, a professional musician is blackmailed into completing the score for his unfinished viola concerto. As Suzanne struggles to keep her double life a secret from her husband, from her best friend, and from the other members of her quartet, she is consumed by memories of a rich love affair saturated with music. Increasingly manipulated by her lover's widow and tormented by the concerto's many layers, Suzanne realizes she may lose everything she's spent her life working for.    A story of love, loss, sex, class, and betrayal, this psychologically compelling novel explores the ways that artists' lives and work interact, the nature of relationships among women as friends and competitors, and what it means to make a life of art.
