I agree to look at work by the masters; For "light", there is none more renowned than Rembrandt, though many exude the similar control and quality.
One book that I recall was "The Shape Of Content" by Ben Shahn
Overall I believe composition is not easy to teach or learn from a single book, but by practice and patience once the concepts are grasped.
