Livia and her family were taken to the gates of hell, Auschwitz. When Eva arrived at the gates of hell she was greeted by the angel of death himself, Dr. Mengele.
The story goes that the Germans immediately gassed everyone under 16 years old at Auschwitz, but Mengele spared her because she "looked Aryan", and told her to pretend she was 16.
Livia, her mother, and her brother Bubi all survived the "death factory" of Auschwitz.  It was a miracle!
Livia has a Holocaust Memoir of her own, titled "I Have Lived A Thousand Years: Growing Up In The Holocaust"
Quote from book:
At the moment of her liberation, Elli is approached by a local German woman:
'We didn't know anything. We had no idea. You must believe me. Did you have to work hard also?'
'Yes' I whisper.
'At your age, it must've been difficult.'
At my age. What does she mean? 'We didn't get enough to eat. Because of starvation. Not because of my age.'
'I meant, it must have been harder for the older people.'
For older people? 'How old do you think I am?'
She looks at me uncertainly. 'Sixty? Sixty-two?'
'Sixty? I am fourteen. Fourteen years old.'
She gives a little shriek and makes the sign of the cross. In horror and disbelief she walks away, and joins the crowd of German civilians near the station house.
So this is liberation . It's come. I am fourteen years old, and I have lived a thousand years.
