Light and darkness. Anthony Doerr uses the closing events to show what light and darkness costs or achieves, rather than simply stating it.
Technology and sound. The ending gives technology and sound a final shape, which is why readers often point to it when they explain what the book is really about.
Sacrifice. Even in the last scenes, sacrifice keeps shaping the choices the characters make.
