A Wrinkle in Time takes place on different planets in the universe, including Earth, Uriel, Camazotz, and others. The setting affects the story because it allows the writer to comment on the way humans live on Earth. In the story, the characters' travels through space allow them to see the dark shadow that represents evil. By traveling through the universe, Meg, Charles Wallace, and Calvin gain perspective on the greater forces alive in the universe and on Earth's place in the universe. For example, Uriel, a planet on which they land to rest, is a tranquil paradise with "a garden even more beautiful than anything in a dream" (page 64). Uriel represents a better world than what is present on Earth. On the other hand, Camazotz, where Meg's father is being held, is a place filled with people who act like automatons and where an entity called "CENTRAL central intelligence" controls their minds. By setting the story on different fictional planets, L'Engle can contrast these worlds with Earth and comment on our own society.
