Sure, here are a few examples of foreshadowing in Tuck Everlasting:
1. In the first chapter, when Winnie Foster is introduced, she is described as being "like a spring lamb." This is a metaphor that foreshadows the idea of rebirth and renewal that is explored throughout the novel.
2. When Winnie runs away from home, she comes across a toad that is stuck in a fence. She sets it free, and this action foreshadows her later decision to help the Tucks.
3. When the Tucks first meet Winnie, they tell her that they are "afraid of their own shadows." This is a metaphor that foreshadows the idea that the Tucks are living in constant fear of being discovered and that their immortality is a curse.
4. When Mae Tuck is in jail, she tells Winnie that "life's got to be lived, no matter how long or short." This is a statement that foreshadows the idea that immortality is not necessarily a good thing and that life is precious because it is finite.
5. When the man in the yellow suit appears, he is described as having a "sharp, eager face." This is a description that foreshadows the idea that the man is not to be trusted and that he has ulterior motives.
