El Domingo De Las Madres by Graham Swift

Set in post-World War I England, the story unfolds on a warm spring day in 1924, focusing on Jane Fairchild, a young maid who works for the Niven family. As the household staff is given the day off to celebrate Mothering Sunday, Jane seizes the opportunity to spend time with her secret lover, Paul Sheringham, the only surviving son of a neighboring family. Their illicit affair is marked by passion and poignancy, as Paul is soon to be married to another woman. The narrative delves into themes of love, loss, and the constraints of social class, while also exploring Jane's reflections on her life and the choices that will shape her future.
