How long can a secret stay buried? The Barnes family has lived in one tiny village for generations. Twins Madeleine and Grace, their cousin Elspeth, their mums and in-laws, old Aunt Susan - all there for ever, in a place barely touched by time. But then two things change - one twin dies, and the villagers are told that their beautiful valley is to be sunk underwater to make a reservoir. How can you live without half of yourself? And how can this tiny community rebuild itself when its past is drowning? As family secrets begin to surface, secrets of love, death and hope, the Barnes family learns that change brings hope as well as sorrow.
