Anthony Doerr's 2014 war novel, All the Light We Cannot See, is a blend of historical fiction and fable that follows a blind French girl and a German orphan during World War II. The story explores themes of survival, isolation, and loss, and the characters' obsessions with radio waves, gemology, and locksmithing. The title references the electromagnetic spectrum beyond human sight, and metaphorically suggests the many untold stories of ordinary people during the war.
