The extraordinary, true story of the North Korean abduction of Japanese citizens, kept for decades in 'invitation only zones', and indoctrinated by Kim Jong Il's secret police. In The Invitation Only Zone, Boynton, an investigative journalist, speaks with the abductees, nationalists and diplomats, and crab fishermen, to try and untangle both the kidnappings and the intensely complicated relations between North Korea and Japan. Part spy thriller, part political investigation.
