The Enchanted Castle follows three children—Jerry, Jimmy, and Kathy—who discover a magical country estate during their school holidays. There, they encounter Mabel, the housekeeper's niece, who pretends to be a fairy-tale princess. The children find a ring that grants wishes, leading to enchanting yet chaotic adventures, especially when their vague wishes result in unexpected outcomes. This charming story blends childlike imagination with subtle magic, appealing to both children and adults alike, reminiscent of E. Nesbit's earlier works.
