Seven schoolgirls form a club named for their suburban town under the energetic leadership of Adele and pledge to be kind, cheerful, and helpful. Their meetings and outings unfold as episodic adventures—secret sanctum discoveries, birthday and holiday parties, a playhouse production, school examinations, summer excursions, and local mysteries that they investigate together. Community service visits, a tense island adventure, and the arrival and rehabilitation of an orphaned girl called Eva provide moments of danger, compassion, and moral growth. The stories blend domestic comedy, schoolroom life, and gentle suspense while emphasizing friendship, cooperation, and practical kindness in everyday youthful enterprise.
