Atonement(2001)

Ian McEwan

On a hot summer day in 1935, thirteen-year-old Briony Tallis witnesses a moment’s flirtation between her older sister, Cecilia, and Robbie Turner, the son of a servant and Cecilia’s childhood friend. But Briony’s incomplete grasp of adult motives—together with her precocious literary gifts—brings about a crime that will change all their lives.
