Winnie speaks in whispers at certain moments in the story, mainly because she wants to be discreet and avoid attracting attention.
Here are some reasons why she whispers:
* Fear of being discovered: She fears that her interactions with the Tuck family, who hold the secret to eternal life, will get them into trouble. She whispers to avoid anyone overhearing their conversations.
* Protecting the Tuck's secret: Winnie understands the gravity of the secret the Tucks possess and the danger they face if it's revealed. Whispering helps to maintain secrecy.
* A sense of reverence: The Tucks' immortality and their connection to nature inspire a sense of awe in Winnie. Whispering becomes a way for her to show respect and humility.
* Creating intimacy: Whispering can also create a sense of intimacy and closeness, particularly when Winnie is sharing her secrets with Jesse Tuck, the young man who is her love interest.
Throughout the book, Winnie's whispers are a symbol of her growing maturity and her increasing understanding of the weight of the Tucks' secret and its impact on their lives.
