Winnie Foster

Winnie Foster is the 10-year-old main protagonist of the novel. Unhappy with how overprotective her family is, Winnie runs away from home and is taken in by the Tucks, an eccentric family of immortal humans.

As the novel progresses, Winnie is faced with her fair share of conflicts; however, perhaps the most important is her internal conflict over immortality. Despite her young age, Winnie finds herself having to think about life and death, and whether eternal life is worth the risk of eternal unhappiness.
