As a child, her decision to take the blame for another's mistake brings devastating punishment at Roman hands. As a young woman, Tiann makes a reckless offer to help preserve the strength of the Celtic tribes, but her plan goes horribly wrong. Alone and hopeless in a distant captivity, she hears news driving her to a desperate escape. How can Tiann respond to the light that calls her and still keep her vows?
