Sarah has given up her career to raise her children in the countryside, while her husband works long hours in London. Alone, she explores the fields and the woods near her home and discovers an enchanting lake, a memorial bench for a boy who drowned in mysterious circumstances, and Finn, a beautiful troubled teenager who plays truant from school. As Sarah pieces the mystery together, an uncomfortable attraction between her and Finn builds, climaxing over one hot summer, threatening to destroy everything that she holds dear. Woven into Sarah's story are the voices of the older generation—Maggie, the RAF nurse and Flavia, the Italian girl. As their stories unfold, a secret is revealed, binding Sarah and Finn in a way that they would never guess.
