An Acceptable Time

An Acceptable Time, the final book in Madeleine L'Engle's Time Quintet, the series that began with the Newbery Award winner A Wrinkle in Time. While spending time with her grandparents, Alex and Kate Murry, Polly O'Keefe wanders into a time 3,000 years before her own.

A flash of lightning, quivering ground, and, instead of her grandparents' farm, Polly sees mist and jagged mountains — and coming toward her, a group of young men carrying spears.
Why has a time gate opened and dropped Polly into a world that existed 3,000 years ago? Will she be able to get back to the present before the time gate closes — and leaves her to face a group of people who believe in human sacrifice?
