It is May 1945 and as church bells ring out Victory in Europe over the Norfolk saltmarshes, Goose's daughter Lil is born. But as Lil enters Goose's world, her father leaves it, in a makeshift boat bound - or so the story goes - for Germany, his home.
Forty years later it is Lil's son, Pip, who begins to make sense of his family's fragmented history. Who was his grandfather, who fell from the sky into Goose's life and then disappeared as suddenly as he came? What was the truth of his mother, Lil, who lived and lost her way between the creeks and the samphire? And what does it all mean for Pip, whose heritage of flood, fireworks, fish and clouds, has left him ill-prepared for life beyond the marshes?
