Spoiler-Free Summary
Marie-Laure LeBlanc goes blind at age six. Her father, the master locksmith at Paris’s Museum of Natural History, builds her a detailed miniature model of their neighborhood so she can learn to find her way by touch. When the Germans invade in 1940, father and daughter flee to the coastal city of Saint-Malo, where Marie-Laure’s reclusive great-uncle Etienne lives in a tall, narrow house. They may be carrying the museum’s most valuable and dangerous jewel.
In a mining town in Germany, an orphan named Werner Pfennig grows up with his younger sister, Jutta, and discovers a talent for building and fixing radios. His skill wins him a place at a brutal academy for Hitler Youth, and later a special assignment tracking down illegal radio transmissions.
Told in short, alternating chapters, the novel follows Marie-Laure and Werner through the war until their stories meet in Saint-Malo during the siege of August 1944.
