A novel by Madeleine L'Engle, sometimes referred to as the fifth book in the Time Quartet (Quintet?) series, but more a part of the O'Keefe family series. In this book, Polly O'Keefe, the daughter of Meg and Calvin O'Keefe, is being sent to her grandparents' house in Connecticut, where she, Zachary Gray, and retired bishop Nason Colubra are transported three thousand years into the past, where the People of the Wind, from A Swiftly Tilting Planet, are facing dangers, and Zachary's own fears drive him to selfish actions.
Arbitrary Skepticism: Considering the other adventures the Murrys, even Meg's parents, have been involved in, it seems odd that they initially reject the bishop's claims about time travel. Mr. Murry explains that it was more a matter of pride than anything else.
Artistic License - History: Three thousand years ago is said to be the time of Abraham, Gilgamesh, and the Pyramids, all of which took place, or were set, between four and five thousand years ago.
Easily Forgiven: Averted. Polly is willing to risk her life to save Zachary, and to heal him later because it's the right thing to do. However, she makes it clear that, even though she would do it again, their friendship is over.
