description: 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?
  
 A quiet visit with her grandparents turns into a lesson in the fluidity of time for Polly O'Keefe when she meets several strangers from overlapping temporal planes and, with them, plays a key role in a prehistoric confrontation.
