The Foretelling, by Alice Hoffman

This book is an acquired taste, it is short, sweet, and infintely deep. It has beautiful writing, and I recommend it to teen girls 10 and up.

Plot summary from Amazon.com:

This atmospheric coming-of-age fantasy tells the story of a teenager who is destined to become queen of the Amazons. The product of a rape and shunned by her distant mother, Rain struggles to find her identity and prove herself. Her first-person narration is accessible while evoking a sense of otherworldliness. She talks of animals and people as sisters. The story unfolds at a measured pace with little dialogue, but the language makes it compulsively readable. Readers will be drawn in by Rain's attempts to win her mother's approval even as the teen begins to question the Amazonian way of life and see a new future for her people. Like the best of myths, this story finds truths in details and emotional insights. Not for everyone, but a treat for fans of Tamora Pierce and Hoffman's other novels.
