What Katy Did at School and What Katy Did Next continue the story of the high-spirited and rebellious American girl, Katy Carr, and her family, who first appeared in What Katy Did. What Katy Did at School is a compelling tale of the intrigues of life at the New England girls' boarding school which Katy attends. Her trials and adventures are all interwoven with a sense of fun and gently ironic good humour. What Katy Did Next describes a tour by Katy of Europe, as she evolves from the child of earlier books into a spirited young woman, and brings to a satisfying close this delightful trilogy.
