A lyrical, captivating and beautiful picture book by Carnegie Medal-winner David Almond, illustrated by Kate Greenaway Medal-winner Levi Pinfold. When a great dam was built by the Kielder Water in Northumberland, the valley below slowly filled with water. But just before this, when the villagers had been moved out, two musicians went back to the abandoned valley. They tore down the boards over the houses, stepped inside and started to play - for this would be the last time that music would be heard in this place. In this astonishing picture book that combines themes of loss, hope and music David Almond pays homage to all musicians, showing the ancient and unstoppable power of creativity.
