Winifred, 15, becomes a modern Cinderella in this rural fantasy. She loves her life raising horses with her dad in Oregon. Until her brother returns home from college with his future-in-laws. They take over her house for a month to plan the wedding. Losing her mother at birth, Winifred isn't prepared for the scary dictator, the bratty child and creepy cat who take over her bedroom. Where else can she escape except the attic, a quiet place with her mother's belongings? When her dad leaves to pick up a prized stallion and her brother deserts her to pick up supplies, Winifred is forced into drudgery. A Fairy Godmonster with a malfunctioning, magic whip shows up by mistake. Although Winifred admires her cool mentor, she's exhausted trying to keep her Fairy Godmonster from being discovered. Overwhelmed with strangers in her house, pregnant mares, ranch duties, household chores, and the handsome usher who makes her toes tingle, Winifred learns how hard it is to grow up.
