The medical experiments conducted in Nazi concentration camps by Dr Joseph Mengele - the angel of death - were amongst the worst atrocities of World War II. He was most notorious for his scientific experiments with twins. Few of the twins survived and those who did were inevitably traumatized and usually severed from their twin. The authors of this book set up the organization Candles to reunite and help the living twins and here dozens of them speak - usually for the first time - about their experiences at the hands of Dr Mengele, about coming to terms with the scars and with survival.
