Eleven-year-old Edie Jasmine Snow has a "perfect" thirteen-year-old sister, two loving parents, and a cat named Dusty. She also has a grandmother she suspects is a witch and a grandfather who insists on calling her Albert. Framed by family summer vacations at the lake, All-Season Edie follows Edie through a tumultuous year in which her beloved grandfather becomes ill. In the face of family tragedy, Edie tries to practice witchcraft, learns to dance the flamenco, meets the Greek god Zeus doing his Christmas shopping at the mall, ruins the most important party of her sister's life and realizes that her family is both completely strange and absolutely normal.
