Mary Craig's Tears of Blood is a masterful account of a history long overlooked and disregarded by the international community, the history of 20th century China's brutal invasion and occupation of Tibet. Ms. Craig has gone even further than most to support the struggles of the Tibetan people, refuting point by point the standard line of the Chinese government, "Tibet has always been a part of China." A must read for anyone even remotely interested in human rights or Tibetan independence.
