In the 'other media' category I can highly recommend 'Pyongyang: A Journey In North Korea' by Guy Delisle[1] which is a graphic novel detailing his few months working in North Korea for a more serious look and into the lives of those who actually live/have lived in North Korea is 'Nothing to Envy' by Barbara Demick[2] which is a detailed, if not somewhat harrowing insight.
