Follows the journey of Boudica, a Celtic princess, and Lhiannon, a priestess who is Boudica's mentor on the Druid isle. When the Romans conquer Britain, Lhiannon fights them while Boudica is married to a king who has surrendered. Theirs is a great love story, but when he dies, the Romans brutalize her and her daughters. In rage, Boudica raises the British tribes and nearly succeeds in driving the Romans from Britain, claiming a place in history. Lhiannon survives and becomes the guardian of the Druid traditions in the new Roman Britannia as high priestess of the Forest House.
