Marie-Laure is twelve years old when the Germans occupy Paris, forcing her and her father to flee to the home of her great-uncle Etienne on the coast. Marie-Laure has been blind since she was six, so her father quickly sets to learning the town and building Marie-Laure a miniature replica so that she can find her way around – not that he allows her to leave the house, for fear of her safety. But her father is hiding a secret, and a valuable one at that. Over in Germany, the young orphan Werner is building and repairing radios and catches the attention of the military. He’s immediately enlisted and begins on a path that eventually collides with that of Marie-Laure, and changes their lives forever.
