When the Nazis invade Budapest in 1944, Margit Kassai begins to document her life in a diary in the form of a letter to her husband, who has been sent to do forced labour. With wry self-deprecation, dark humour and an incredible attention to detail, Margit describes the persecution of Jews and how she feels working in children's homes and living under a false identity. Even as bombs fall around her, she braves the streets to find food for the children in her care, writing unflinchingly of the suffering she endures and her determination to see her husband again.
