“Annie loved pretend stuff. But Jack was eight and a half. He liked real things.”


(Chapter 1, Page 1)

The author introduces the contrasting personalities of Jack and Annie in this quote. Jack’s preference for “real things” highlights his skepticism and realistic approach. He does not quite believe that they’ve their way to the Cretaceous Period, and he approaches the dinosaurs like a scientist. In contrast, Annie’s love of “pretend stuff” signals her openness to the imagination. She accepts their circumstances and that something magical has happened, even if she can’t explain it. This initial dichotomy sets up the siblings’ differing responses to the magical events they experience.
