Pages of a weathered original sonata manuscript - the gift of a Czech immigrant living in Queens - come into the hands of Meta Taverner, a young musicologist whose concert piano career was cut short by an injury. The gift comes with the request that Meta find the manuscript's true owner - a Prague friend the old woman has not heard from since the Second World War forced them apart - and to make the three-part sonata whole again.
Leaving New York behind for the land of Dvorák and Kafka, Meta sets out on an unforgettable search to locate the remaining movements of the sonata and uncover a story that has influenced the course of many lives, even as it becomes clear that she isn't the only one seeking the music's secrets.
