All the Light we Cannot See by Anthony Doerr
This beautiful book reveals darkness imbued with light. Not the light from the bombs that fall on St. Malo late in World War II. Nor the brilliance of the world's largest natural diamond, smuggled away from the occupying army by an employee of the Paris Natural History Museum.
Not even the light of knowledge put out over the radio waves in scientific broadcasts for children. Nor yet the light of courage in a blind girl conveying messages to the French resistance.
All this light is impressive, of course. Still more inspiring is the hidden light in the human heart: the love between a father and his blind daughter, and the love for a friend and an enemy that beats in the heart of an orphan boy from the Hitler Youth.
