Memories come to Katya in her dreams - images and stories from a past that isn't her own. Are these ghosts real? And what of the memory she seems to have of a treasure, two centuries old? A novel that spans the history of Europe - from revolutionary France to the world wars, the Prague Spring, post Brexit Britain, and beyond - and the irresistible story of an extraordinary woman. The new novel from the author of "Not Forgetting the Whale".
