Book that belonged to a Polish Jewish student in hiding with a false identity

Book that belonged to Roza Kwar. After Nazi Germany occupied L'vov, Poland (L'viv, Ukraine) in June 1941, Roza, 14, and her parents, Benzion and Tinka, were moved to the Jewish ghetto and assigned to forced labor. In August 1942, Benzion purchased false papers for her. She escaped and went to live with Krystyna Moskalik, a Polish schoolteacher, in Sieciechiowice. That area was liberated by the Soviet Army in January 1945 and in May, after the war ended, Roza went to Krakow to further her education. She continued to live under her false identity as a Catholic because of the intense antisemitism. Roza learned that her parents had died of typhus and only three of her large extended family had survived the destruction of the ghetto. Family members in New York, learning that she might have survived, found her in Krakow. They arranged for Roza and her maternal aunt, Frieda Herzer, to emigrate to the United States via Cuba in January 1948.
