Not without my sister

Summary: "1944, Germany. After years of hiding from the Nazis, Rachel Epstein and her little sister, Mindel, are captured by the Gestapo and sent to the concentration camp at Bergen-Belsen. The only ray of light for either girl is that they are together. But on arrival, Rachel is sent to work in a brutal factory, while four-year-old Mindel is sent into the so-called "star" camp for Jewish prisoners. Rachel knows her sister will have no chance of survival--unless she can find someone to take care of her. As she works in the windowless, airless factory--filling munitions casings with chemicals that burn her fingers and make her eyes sting--the only thing that keeps Rachel going is the thought of her little sister. Separated by barbed wire and SS guards who ignore their pleas, can the orphaned sisters ever dare to hope that they'll find their way back to each other? And to freedom?"--Page 4 of cover.
