How to write a theme paragraph on family or hope

Hope is a theme throughout the novel and it is the underlying factor that keeps the children alive in the most difficult of circumstances. They hope they will be reunited with their parents; Ruth and Bronia hope to find their brother; and the journey to Switzerland is made in hope of a better life, and of being with their parents again. Even their new life is inspired by hope for a better day.

Family is a constant theme in the novel, and even the people affected by meeting the children are reminded of their own family. Everything that happens in the novel is driven by family. Joseph escapes from his imprisonment to go and find his wife and children. Ruth is wise beyond her years, acts as a mother to her siblings, and is determined to keep them together. When they meet Kurt Wolff and his wife, the couple wants to adopt the children even though they know they are intent on finding their real parents, the Wolffs identify with Edek and Jan because they had sons themselves.
