Dusie always knew puberty was going to be confusing, but she never realized it was going to be catastrophic--until she wakes up one morning to find that her hair has turned into a writhing mass of slithering snakes and discovers the real truth about her family:  her mother is a Gorgon--right out of Greek mythology--and she was named after her mother's younger sister, Medusa. Her mother had hoped that Dusie's being half-mortal would protect her from inheriting the family curse.    Still reeling from this revelation, Dusie tries to keep her snakes under wraps. But after a boy she likes in school almost exposes her, she discovers another family secret--just one look from Dusie's snakes has the power to send someone right into his own personal Stone Age.
