Set in 1952 rural Wales, Go Through the Waves is an exploration of three generations of women. There is the grandmother, Gwyn Thomas, who continuously builds statues to communicate with unseen people, and who drowns in her search for them. Then there is Jane Evans who volunteers in the Korean War, and returns traumatised and haunted by the soldier who she killed accidentally and with whom she attempts to communicate through letters. Finally, there is the narrator, Megan, who believes that her unexpected pregnancy is caused by a woman she loves, and who embodies her family's legacy through remarkable visions.
