Gabriella stands on a gallows one day before her 19th birthday in 1718. She tells her story to a young blacksmith, a surly milkmaid, and a mute dwarf who is much more than the muckraker he seems. The pampered daughter of a count, Gabriella’s entire existence has been her music, until one afternoon’s sensual exploration leads to the shame of two noble families and her exile to a convent school for orphan girls, the Ospedale della Pieta in Venice, Italy. Antonio Vivaldi, the school’s Maestro of the Concerto, teaches the students and composes.

She tells of her friend, Veronica, a sublimely talented violinist whose cold eyes hide tragic secrets and of whose murder she now stands convicted. With tears in her eyes, she speaks of her love, Raphael, the handsome overseer whom she had planned to marry. The story of her desperate attempt to learn the truth of a terrible curse that took her own child’s life, and save Veronica from a dark affair, holds the crowd’s rapt attention.

Now she must escape with the help of her friends, from the Ospedale, and perhaps those in the crowd assembled to watch her hang.
