The few that survived Auschwitz relied on wit, skill or just plain chance.
Lale Sokolov is one of the few who did survive Auschwitz. He did so by becoming the Tätowierer (responsible for carving the numbers into the arms of his fellow prisoners). His story is recounted in the novel The Tattooist of Auschwitz. Written by Heather Morris, the book follows Lale from his first days at the notorious death camp until the end of the war when he and the rest of the survivors are freed from captivity. Instead of outright murdering him, the Germans use his multi-lingual ability for their own uses.
While this is happening, Lale is trying to save as many of his fellow prisoners while he is falling in love with another prisoner, Gita. It is their relationship and mutual love that helps him to stay alive when he knows that death is all around him.
This book is amazing. If nothing else, it is a reminder that hope and love can still exist when it seems impossible that neither should exist.
I absolutely recommend it.
