All the Light We Cannot See, by Anthony Doerr, is a Pulitzer Prize-winning novel set during World War II. It follows two young protagonists: Marie-Laure LeBlanc, a blind French girl who flees Nazi-occupied Paris with her father, a museum locksmith carrying a possibly cursed diamond; and Werner Pfennig, an orphaned German boy whose gift for radio mechanics leads him into a brutal Nazi academy and the army. Their paths eventually converge in the besieged coastal town of Saint-Malo in 1944. Written in luminous, poetic prose, the novel explores resilience, human connection, and the invisible light of goodness persisting amid darkness.
