A young, sunlit child nicknamed Little Sunshine accompanies her busy parents on a family holiday and supplies the book's episodic focus. The narrative sketches her earnest honesty, quick tempers, and delight in domestic rituals as she helps pack, admires her curls and new boots, rides by steam and boat, and encounters water and unfamiliar scenes. Gentle vignettes show her interactions with servants and family, small mischiefs and prompt contrition, and a child's fresh curiosity about everyday objects. The work proceeds through illustrated, self-contained episodes that emphasize affectionate humor and observational detail rather than a single dramatic plot.
