We meet Werner as a young orphan in a bleak mining town in Germany. Germany is already turning into a war machine, one fueled by the coal mines that Werner and all the boys in the orphanage are going to be sent down into when they get old enough. But Werner is a bit of a prodigy. He has the ability to fix radios everyone else has given up on, and when his talent catches the right person's attention, he's given a chance to escape from the mines. He takes this chance, getting a place at a national school that, with the use of shocking brutality, is molding the future leadership of the Third Reich.
Marie-Laure is a blind girl living in Paris with her father. She's a great character, extraordinarily brave, and indeed, she needs to be brave as she flees Paris, loses her father, and gets involved with the French Resistance.
The narrative alternates between these two characters and they do not meet until very close to the end of both the war and the book. The writing is lovely, and the book is full of interesting and well-developed characters.
Sometimes I look around at the books in the library where I work and despair-- the whole world of literature is darkness, except for those books I've inhabited for a while and made my own, and there are so many I'll never get to. If you enjoy fiction set during World War II, this list contains other good books that you may not want to leave in the dark.
