No. All the Light We Cannot See is historical fiction. Marie-Laure, Werner and the other main characters are invented, and so is the Sea of Flames, but the war and the Battle of Saint-Malo in August 1944 are real.

Doerr spent about ten years on the book, most of it on research.

Are the characters real people?

The central characters, their families and the legend of the diamond are products of Doerr's imagination. The novel's own story is told in a way that makes them feel real, which is why readers often ask.

What is real in the book?

The setting is real: the American siege of Saint-Malo in August 1944, during the Allied effort to free France. The town was nearly destroyed in the war and rebuilt afterward. Doerr read wartime diaries and letters and visited Germany, Paris and Saint-Malo while researching.

The book also includes real period detail, such as German radio technology and Nazi training schools.

How did Doerr come up with it?

In 2004 Doerr was on a train in New York when a passenger became angry that his phone call dropped as the train entered a tunnel. Doerr thought about how people take long-distance communication for granted, and wanted to write about a time when it still felt miraculous. His first idea was a girl reading to a boy over the radio.

A visit to Saint-Malo in 2005 decided the setting.

Is the Netflix series true?

No. The 2023 four-part Netflix series is also based on the novel, and the producers changed some of it, including aiming for a more hopeful ending, with Doerr's approval.
