This is a beautiful story of magical realism. I unintentionally gobbled it up in an evening. I love Luna as a character: full of fire and love for her home and her family in a place that is "cursed." If you drink the water it makes you sick. One day her sister Willow accidentally drinks the water, and Luna sets off to figure out a way to save her. Chapters of Luna's story alternate with a story of sprites getting ready to leave this world for a place that humans have not ruined.
