A novel by Creator/MadeleineLEngle, 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 ''Literature/ASwiftlyTiltingPlanet'', are facing dangers, and Zachary's own fears drive him to selfish actions.

* AllGirlsWantBadBoys: Averted. Zachary's amorous interest in Polly is largely one-sided, even before his FaceHeelTurn.
* ArbitrarySkepticism: 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.
* ArtisticLicenseHistory: 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.

* ExactlyWhatItSaysOnTheTin: The People Across the Lake are people who live across the lake from the People of the Wind.
* GenerationXerox: Sort of. Polly has Meg's talents and some of the same issues with her looks, and her brother Charles is somewhat like Charles Wallace, though without the extraordinary abilities.
