For readers of Schindler's List, The Man Who Broke Into Auschwitz, and The Boy in the Striped Pajamas comes a heartbreaking story of the best of humanity in the worst of circumstances. I tattooed a number on her arm. She tattooed her name on my heart. In 1942, Lale Sokolov arrived at Auschwitz-Birkenau. He was assigned to tattoo the prisoners marked for survival – he scratched numbers into the arms of his fellow victims with indelible ink, creating one of the strongest symbols of the Holocaust. Waiting in line to be tattooed, filled with fear and trembling, stood a young girl. For Lale – a dandy, a daredevil, a little gambler – it was love at first sight. And he was determined not only to survive himself but also to ensure that this woman, Gita, did as well. Thus begins one of the most life-affirming, courageous, unforgettable, and human stories of the Holocaust: the love story of Lale and Gita.
