Knowing my affinity for radio, my book eating 30 year old son gave me as a Christmas present the Pulitzer Prize winning fiction book "All the Light We Cannot See". A theme throughout the book is radio - from repair to quasi-pirate to military use to number station. It is mainly set in Europe during the 30's and 40's. Interesting story, 500 pages but a real page turner - I knocked it out in two days over Christmas.
