Two sisters in 18th century Venice, abandoned as babies, grow up to different futures. One marries into a great aristocratic Venetian family, and the other becomes a violin virtuoso and Antonio Vivaldi's muse.

A novel of music, intoxication and betrayal is inspired by the true story of Anna Maria della Pietà, a Venetian orphan and violin prodigy who studied under Antonio Vivaldi and became his star musician--and biggest muse.
