The Unopened Score

Some things can't be said out loud. They have to be played.
Six months after the events of Forbidden Notes, Christian Russo has built a quiet life at Ashwood University - except for two sealed boxes that have followed him from Rome to Milan to Lyon, never opened, never explained. Inside them: his father, and a composition he abandoned seven years ago.
Then Catalina Claire asks the question no one else has dared to. What's in them?
Told across two timelines - Now, where Christian and Catalina are falling into something neither can name, and Then, the story of the boy who packed his grief into cardboard and taped it shut - The Unopened Score is a novel about the music we're too afraid to finish, and the people who make us brave enough to try.
Forbidden Notes, Book Two. You don't need to have read Book One - but if you have, you'll hear the echo.
