At sixteen years old, Klara Wizel is full of life with a loving family. But her spirit quails when she and her family are swept up with fifteen thousand other Hungarian Jews and forcibly transported to one of the world's most infamous concentration camps: Auschwitz-Birkenau. There Klara comes face to face with one of history's most infamous Nazi doctors, nicknamed The Great Selector and the Murderer in White, Josef Mengele. Klara watches in horror as Mengele sends her parents, her younger brother, and her older sister to the gas chamber, leaving Klara and her two remaining sisters to be housed like animals in the women's barracks. They live in constant fear of Mengele choosing them for one of his cruel scientific experiments.

As the Russian allies close in, Mengele steps up his selection process and sentences Klara to the gas chamber. But in a miraculous turn of events, Klara escapes both the chamber and Auschwitz itself and makes her way across war-torn Europe back home to Sighet.

The only survivor of record to escape Mengele's notorious death selection process, Klara's is an extraordinary and inspirational story of survival and resilience in the face of deep loss and extreme cruelty.
