How does the author use symbolism in the novel, Torn Thread?

The two symbols used repeatedly in Torn Thread are thread, which represents the tangled and interwoven fate of the Jewish people living under the Nazi regime, and stars, which represent hope, beauty, and the presence of God in the world. From the beginning of the story, Eva uses thread as a way to stay connected to her family. She knits sweaters to keep Rachel warm, untangling yarn from old sweaters to make new ones.
