Alma Braithwaite was a teenager in Exeter when her boarding school was bombed in 1942. Twenty-one years later, she remains alone in the house where she grew up, teaching music at her old school, unable to move on from the tragic events of the war. It takes the arrival of an innovative new headmistress and a new pupil - the daughter of a man Alma hasn''t seen since 1942 - to bring back the painful yet exhilarating summer that followed the air-raids and jolt her out of the past.
