1976: Peggy Hillcoat is eight. She spends her summer camping with her father, playing her beloved record of The Railway Children and listening to her mother's grand piano, but her pretty life is about to change. Her survivalist father, who has been stockpiling provisions for the end which is surely coming soon, takes her from London to a cabin in a remote European forest. There he tells Peggy the rest of the world has disappeared. Her life is reduced to a piano which makes music but no sound, a forest where all that grows is a means of survival. And a tiny wooden hut that is Everything. She is not seen again for another nine years. 1985: Peggy has returned to the family home. But what happened to her in the forest? And why - and how - has she come back now? As if laying a trail of breadcrumbs for readers to follow, Claire Fuller leads us on an extraordinary and heart-stopping journey as light as it is dark and as joyful as it is horrifying.
