Plot Summary

Marie-Laure grows up in Paris, the beloved daughter of Daniel LeBlanc, master locksmith of the National Natural History Museum. Blind from the age of 6, Marie-Laure learns to navigate her world through the patience and persistent guidance of her father. He builds a scale model of her neighborhood so that she can learn her way around independently. He also gives her Braille books, opening her mind and imagination to a world beyond her own.

Werner grows up in a protestant orphanage with his younger sister, Jutta. Extremely intelligent, Werner builds his own radio, which picks up far away broadcasts from cities around the world. These broadcasts, particularly a scientific program for children given by a Frenchman, give him and Jutta hope for a better life. His is life marked by poverty and a fear of working in the mines where his father died, so Werner seizes an opportunity to escape the mines through admission to a Reich-sponsored school. Though he gets the education of his dreams in some ways, the price he pays for it is his humanity.

Werner and Marie-Laure each face considerable hardships while growing up: Werner confronts poverty without the help of his parents; Marie-Laure confronts the loss of her mother at her birth and must learn to deal with her blindness. However, their challenging histories also reveal their strengths: Werner’s intelligence and creativity; Marie-Laure’s imagination and love of the natural world.

The novel’s different sections converge upon their meeting, which forms an extended climax within the novel. While the novel is not a traditional love story, Werner, nevertheless, falls in love with Marie-Laure when he sees her walk down the street in Saint-Malo. Werner rescues Marie-Laure from death and helps her escape the city, which is still under siege, redeeming himself through this act of courage in defiance of his so-called duty to the Reich.

The story continues beyond the end of the war, detailing the consequences of Werner’s act of humanity, and revealing Marie-Laure’s survival. Jutta’s son, Max, represents the survival of Werner’s bright curiosity, no longer overshadowed by poverty or history.
