In 1941, aged twelve, Helga Weiss, her mother and father were forced to say goodbye to their home, their relatives and all they knew, and were interned in the Nazi concentration camp of Terezin. For the next three years, Helga documented her experiences there, and those of her friends and family, in a diary. Then they were sent to Auschwitz, and the diary was left behind, hidden in a wall. Helga survived the Holocaust, managed to retrieve her diary and complete the journal of her experiences.
