What does the bond between Denny and Zoë symbolize?

The bond between Denny and Zoë symbolizes the strength of family love in overcoming adversity. Throughout the story, their relationship exemplifies how deep familial connections can provide support during difficult times. Denny faces numerous challenges, including personal loss and legal battles, yet his love for Zoë remains a powerful force that motivates him to persevere. Their interactions illustrate the unconditional love and dedication that exists within a family, showcasing how this bond can help them navigate life's hardships together.

The other options do not capture the essence of their relationship as effectively. While financial success, independence, and the challenges of parenting are relevant themes in the book, they do not directly represent the core symbolism of the bond between Denny and Zoë, which is primarily about the resilience and strength that comes from familial love during adversities.
