Award-winning BBC journalist John Sweeney is one of the few to have witnessed at first hand the devastating reality of life in the controversial and isolated nation of North Korea. Posing as a university professor, Sweeney went undercover to gain unprecedented access to the world's most secret state. He spoke to people who have seen the horrific dark side of the regime and saw things which have been hidden for years from the eyes of the western world: huge factories with no staff or electricity; hospitals with no patients; uniformed child soldiers; and the world-famous and eerily empty DMZ - the De-Militarized Zone where North Korea ends and South Korea starts - all framed by the relentless flow of regime propaganda from omnipresent loudspeakers. Sweeney also visited South Korea and met defectors from the North who told him the other side of the story: gulags within a gulag state, dire poverty, blunted lives, hideous torture, effective infanticide of disabled babies, stick-limbed children dying of famine and mass graves of political prisoners that could only be dug when the spring thaw set in. With the world's eyes focused on North Korea, Sweeney's timely account is a stunning piece of reportage from the country the author describes as the strangest place he's ever visited. A combination of first person experiences, new and revealing interviews, and history, North Korea Undercover examines the country's troubled history and provides a window into life there today.
