The bestselling author of National Jewish Book Award Finalist The Boy Who Followed His Father Into Auschwitz is back with another powerful nonfiction book for young readers, this time spotlighting twin sisters whose worlds were turned upside down when Adolf Hitler assumed power. Through trials and tribulations, hardships and disasters, the bond between twin sisters Friedel and Gina Rosenthal was unshakable. They were only nine years old when the Nazis came into power in Germany. When the girls were fourteen, they, along with their family, were deported to a refugee camp in Poland. After the Nazis invaded Poland, the family suffered even more heartache…and Friedel and Gina soon found themselves alone. Through the atrocities that followed – the ghetto and the concentration camps – they helped each other stay alive. They grieved their losses and learned to survive…together. “The twins’ courage and devotion to each other is inspiring, making this a worthy addition to books about the Holocaust.” - ALA Booklist, starred review Jeremy Dronfield is a biographer, historian, novelist, and former archaeologist.
