Jane Yolen uses three voices to tell the story of the white-haired child, Jenna, who is found by the warriors of the Hame: straight-forward story telling, folk songs, and academic analysis. Among the three sources emerges a world in transition, awaiting the white leader who is to take their world through a disruptive time to a new world order.
Jenna, also called Jo-ann-enna, learns that she is this white warrior. Her growth into the prophecy is rocky, resisted by the leaders of her world, accepted by some. The calling forth of her dark sister, Skalda, visible only by moonlight and candle light, helps her to accept her fate.
Jane Yolen has a gift for world building that creates an articulate, believable world for Jenna to come into her powers. This book, the first of three, is a solid introduction to her life and surroundings.
