Tess Gerritsen  book cover

In a shadowy antiques shop in Rome, violinist Julia Ansdell happens upon a curious piece of music and is immediately entranced by its unusual composition. Back home in Boston, from the moment Julia’s bow moves across the strings, the music has a terrifying and inexplicable effect on her young daughter, who seems violently transformed. Her quest beckons Julia to the ancient city of Venice, where she uncovers a dark, decades-old secret involving a dangerously powerful family that will stop at nothing to keep Julia from bringing the truth to light.
