When Polly O'Keefe visis her grandparents in Connecticut, she plans a quiet fall, filled with study and frequent forays to the star-watching rock. A welcome diversion comes from Bishop Colubra, an old family friend, who is fascinated by the ancient hieroglyphics on stones found in the area. And a pleasant surprise is the appearance of Zachary Gray, the boy Polly had met in Greece the previous summer.
Zachary's sudden appearance is only the beginning of a series of events which turn Polly's quiet visit into an extraordinary one. While out walking, she encounters several strangers who are mysteriously compelling: Karralys, a tall, blue-eyed man who, Polly discovers, is a druid; Anaral, a beautiful young woman and a disciple of Karralys; and Tav, a fearless warrior. They all come from a society that existed three thousand years ago!
What seemed to be coincidences are gradually revealed as part of a pattern, an overlapping of planes of time. The bishop's research and Zachary's arrival are somehow related to the opening of a time gate which draws Polly into this ancient world. Traveling across the millennia to play a crucial role in a prehistoric confrontation, Polly discovers that time micans everything and nothing in the history of human relationships, and, finally, that love is the tie that binds.
