The novel “All the Light We Cannot See” follows the lives of three people whose paths cross when Saint-Malo, a French town under German occupation, is bombed in August 1944. Daniel Leblanc, the father of Marie-Laure Leblanc, is a locksmith who works at the Museum of Natural History in Paris, where Marie-Laure Leblanc is raised. Marie-Laure loses her sight as a young child, but her father builds her a scale model of the neighborhood so she may learn how to traverse it on her own. She is 12 years old when the prospect of a German conquest of Paris becomes too overwhelming to ignore. This occurred in June 1940. Daniel and Marie-Laure depart Paris and make their way to Saint-Malo, where they take up residence with Etienne, her great-uncle, and Madame Manec, his housekeeper.

Marie-Laure is unaware that Daniel departs Paris with a possibly important object in his possession. The Sea of Flames diamond, a fabled gem, is a property of the Museum of Natural History. The museum directors created three replicas in response to the danger of occupation. Daniel and other members of the staff send out three of the stones, but the fourth one stays at the museum. Nobody is certain if the stone they own is genuine or a replica. Once at Saint-Malo, Daniel works to create a scale model of the city so Marie-Laure may learn how to traverse it. He also conceals the diamond in the model of Etienne’s home that he creates. Daniel is called to return to Paris in December 1940, and while traveling there, he is detained. He is sent to a German detention camp, where he finally perishes.

Many of the French inhabitants have been mobilized by Madame Manec to take part in acts of resistance against their German oppressors. Etienne and Marie-Laure are initially apprehensive but gradually start participating. Etienne can make a unique contribution since his home has a powerful radio transmitter tucked up in a hidden attic floor. To preserve his brother’s memory before the conflict, Etienne used it to air recordings of his deceased brother giving scientific programming to kids. Now, to undermine the German war effort, he broadcasts codes and messages via the radio transmitter. By taking this step, he and Marie-Laure can maintain their optimism even after Madame Manec died in 1942.

Werner Pfennig and his sister Jutta were raised in an orphanage in Germany at this time. Werner possesses a remarkable aptitude for mathematics, technology, and science. Werner learns how to fix and rebuild electronics after he and Jutta accidentally come across an abandoned radio. Additionally, he has access to a secret French program where a man uses everyday language to convey complex scientific ideas. Werner’s abilities get local notice as the Nazi party gains power in Germany, and when he is fourteen, he is admitted into a specialist training school. He believes that having this chance would help him have a better future, but Jutta worries that her brother may become infected with Nazi philosophy. Werner does see a lot of brutality and cruelty while in school, including his close friend being severely brain-damaged by beatings.

Werner’s age is lied about when he is sixteen for him to serve on the German front lines. He travels for the next two years looking for any people who are using unauthorized radios in occupied German territory. Volkheimer, a fellow German soldier, collaborates with Werner. Werner struggles with moral dilemmas, but he is especially appalled when one of his fellow soldiers murders a lady and a child. By the spring of 1944, he and his colleagues are transferred to Saint-Malo, where he is shocked to learn that a guy transmitting secret codes has the same voice as the one from the show he listened to as a youngster. Unsure of what to do, Werner conceals this knowledge while simultaneously spying on the home that is broadcasting the signal and spotting Marie-Laure.

Von Rumpel, a Nazi official, has been given the mandate to collect and classify diamonds from German regions under occupation at this time. Due to his sickness and his belief that the diamond will offer him immortality, he becomes fixated on locating the fabled Sea of Flames. He progressively locates three of the four stones between 1940 and 1944, but the real stone remains a mystery. Finally, he follows the stone to Saint-Malo, the location of Daniel Leblanc’s last known dwelling. Allied forces started bombing Saint-Malo in August 1944.

The bombing has an impact on all three of the main characters: von Rumpel takes use of the chance to travel to the house to look for the diamond, Marie-Laure is left alone in her home and unsure of what to do, and Werner is trapped in a cellar when a building collapses on him. Marie-Laure hides in the attic with Etienne’s radio transmitter and the diamond as she hears a visitor enter the house. She remains undetected for four days, disseminating the signals Werner gets while he is confined to the cellar.

Finally, Werner gets out of the cellar and runs towards the house. When Von Rumpel attacks the young soldier, Werner shoots and kills him because he thinks Werner is also searching for the diamond. Then, Marie-Laure can emerge from concealment, and Werner assists her in reaching safety. Marie-Laure gives Werner the key to a secret grotto where she hides the diamond as they exit the town. 

After they split up, Marie-Laure meets up with Etienne again and moves in with him in Paris. In jail, Werner becomes unwell. A few months later, he accidentally stumbles on a landmine and dies while in a delirium. Some of Werner’s belongings are delivered to Volkheimer years later, in 1974, and Volkheimer delivers them to Jutta. Following these hints, Jutta ultimately runs across Marie-Laure, who has since become a scientist and given birth to a kid. Marie-Laure speculates that Werner may have returned to retrieve the diamond, although it is more likely that the precious stone was left in the grotto to be carried out to sea.
