What Happens, Part by Part (Contains Spoilers)
Two childhoods
Marie-Laure grows up in Paris, where her father is a locksmith at the Museum of Natural History. After she loses her sight, he builds a small model of the neighborhood so she can learn the streets by touch. Werner grows up in an orphanage in a German mining town.
The gift for radios
Werner teaches himself to fix radios. A broadcast he and his sister Jutta hear as children stays with him, and his talent catches the eye of the authorities, who send him to an elite military school.
The stone and the flight
As the Germans approach Paris, Marie-Laure's father is entrusted with a precious gem from the museum, and she and her father flee to Saint-Malo, where they live with her great-uncle Etienne. A German sergeant major is hunting for the stone.
Training and war
At the school, Werner sees how cruelty is taught and how a friend named Frederick is treated. Later he is sent to the front, where his skill at tracing radio signals is used to find hidden transmitters.
Saint-Malo, 1944
Marie-Laure and Etienne use a hidden radio to broadcast messages. Werner, tracking the signal, arrives in the town as it is bombed, and the two timelines meet in the same house.
After the war
The final chapters jump forward, showing what remains of the war's damage. Marie-Laure's life continues, and the book ends by asking what we owe to the people we never meet.
5 Key Takeaways
