Heaven Becomes Hell: A Survivor's Story of Life Under the Khmer Rouge (Yale Monograph No. 50). A rare, first-person account of four harrowing years, mostly tragic, sometimes touching, and sometimes even humorous. Ly Y and his wife survived, but their 18-month old child died during the forced march from Phnom Penh after their family and the city's inhabitants were driven out by the Khmer Rouge in 1975.
