Once Jacob Gutgeld lived with his family in a beautiful house in Warsaw, Poland. He went to school and played hide-and-seek in the woods with his friends. But everything changed the day the Nazi soldiers invaded in 1939. Suddenly it wasn’t safe to be Jewish anymore.One afternoon, eight-year-old Jacob slipped through a hole in the ghetto wall to meet Alex Roslan, a kind Christian man who agreed to be his new “uncle.” The Roslan family, at the risk of their own lives, kept Jacob’s identity as a Jew hidden.Every day of hiding meant a new danger and a threat of discovery. Jacob worried about his real family and longed to go to school and play outside like the Roslan children. Yet the fear, the hardships, and the hunger brought Jacob closer and closer to all the Roslans–until at last the time of hate and war came to an end and a new chapter began in all their lives.
