All the Light We Cannot See

All the Light We Cannot See is a 2014 war novel by American author Anthony Doerr. The novel is set during World War II. It revolves around the characters Marie-Laure LeBlanc, a blind French girl who takes refuge in her great-uncle's house in Saint-Malo after Paris is invaded by Nazi Germany, and Werner Pfennig, a bright German boy who is accepted into a military school because of his skills in radio technology. The book alternates between paralleling chapters depicting Marie-Laure and Werner, framed with a nonlinear structure. The novel has a lyrical writing style, with critics noting extensive sensory details. The story has ethical themes, portraying the destructive nature of war and Doerr's fascination with science and nature.

Doerr drew inspiration from a 2004 train ride. During the ride, a passenger became frustrated after his telephone call disconnected. Doerr felt the passenger did not appreciate the "miracle" of long-distance communication and wanted to write a novel about appreciating said miracles. He decided to set the novel in World War II with a focus on the Battle of Saint-Malo after visiting the town in 2005. Doerr spent ten years writing All the Light We Cannot See, with much time dedicated to research on World War II.

Scribner published All the Light We Cannot See on May 6, 2014, to commercial and critical success. It was on The New York Times Best Seller list for over 200 weeks and sold over 15 million copies. Several publications considered it to be among the best books of 2014. The novel won the Pulitzer Prize for Fiction and the Andrew Carnegie Medal for Excellence in Fiction, and was shortlisted for the National Book Award. A television adaptation produced by 21 Laps Entertainment was announced in 2019 and was released on Netflix as a four-part miniseries on November 2, 2023.

All the Light We Cannot See is structured nonlinearly; sections taking place during the Battle of Saint-Malo in August 1944 are interspersed with sections about earlier times starting in 1934 and going in chronological order. Additionally, the point of view alternates between Marie-Laure LeBlanc and Werner Pfennig between chapters. For simplicity, their respective narratives preceding the Battle of Saint-Malo along with the events during and after the battle have dedicated sub-sections.

Marie-Laure LeBlanc is a girl who lives in Paris with her father Daniel, the master locksmith at the Museum of Natural History. She went blind at the age of six in 1934. Since then, Daniel has helped her adapt to her blindness by creating a model of Paris for her to feel and training her to navigate it. Marie-Laure hears stories about a diamond known as the Sea of Flames that is hidden within the museum; the diamond is said to grant immortality at the cost of endless misfortune to those around the owner. The only way to end the curse is to return the stone to the ocean, its rightful owner.

When Nazi Germany invades France in 1940, Marie-Laure and Daniel flee to the coastal town of Saint-Malo to take refuge with her great-uncle Etienne, a reclusive, shell-shocked veteran of World War I who spends his time broadcasting educational audio recordings, produced by his deceased brother, across Europe. Unknown to Marie-Laure, the museum has entrusted her father with either the Sea of Flames or one of three exact copies that were made to protect the original gem. Months later, while building a model of Saint-Malo for Marie-Laure, Daniel is arrested and suspected of conspiracy. Other than a few letters he manages to get out of prison, he is not heard from again, leaving Marie-Laure alone with Etienne and his longtime maid and housekeeper, Madame Manec.

Madame Manec participates in the French Resistance along with other local women. Their activities have some success, but Madame Manec becomes ill and dies. Marie-Laure and Etienne continue Madame Manec's efforts over the next few years, transmitting top-secret messages by radio transmitter. Eventually, while Marie-Laure is going home to deliver a routine Resistance message from the bakery, she is visited by Sergeant Major Reinhold von Rumpel, a Nazi gemologist who is searching for the Sea of Flames and has tracked the real one to Saint-Malo. Von Rumpel asks the frightened Marie-Laure if her father left her anything and leaves when she says "just a dumb model". Etienne takes over Marie-Laure's role of message-deliverer, and she later opens the model of Etienne's house on the Saint-Malo model and finds the Sea of Flames. Etienne is eventually arrested and sent to Fort National on false charges of terrorism.

In Nazi Germany, Werner Pfennig is an orphan in the coal-mining town of Zollverein. He is exceptionally bright and has a natural skill for building and repairing radios. He discovers this skill in 1934 at the age of eight after he finds a broken radio with his sister Jutta, fixes it, and uses it to hear science and music programs transmitted across Europe. In 1940, Werner's skill earns him a place at the National Political Institute of Education at Schulpforta, a draconian state boarding school teaching Nazi values, which Jutta hates. She has been listening to French radio broadcasts about Germany's war crimes during its invasion and is angered by Werner's accepting a place at Schulpforta. Before leaving for Schulpforta, Werner promises Jutta he will return to Zollverein in two years to fly away with her on an airplane.
