Book excerpt: The true story of nineteen-year-old Jordana Lebowitz’s time at the trial of Oskar Groening, known as the "bookkeeper of Auschwitz", a man charged with being complicit in the deaths of more than 300,000 Jews. A granddaughter of Holocaust survivors, Jordana was still not prepared for what she would see and hear. Listening to Groening’s testimony and to the Holocaust survivors who came to testify against him, Jordana felt the weight of being witness to history – a history that we need to remember now more than ever.
