When pages of a worn sonata manuscript come into the hands of Meta Taverner, a young musicologist, it appears to be the undiscovered composition of a master. But there is no indication of who the composer might be. Leaving New York behind, Meta sets out on a search to locate the remaining movements of the sonata, even as it becomes clear that she isn't the only one after the music's secrets.
