Un Momento Favorable

Polly couldn't be more surprised when discovering in her own flesh the mystical forces that surround her grandparents' farm. She will soon find herself in a landscape surrounded by lightning, fog, a trembling earth beneath her feet ... and a group of young men armed with spears that are heading towards her. 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?
