The six Mitchell children of Friendly Gables, Quebec, are suddenly thrust into a frenzy when mother Mitchell presents them with twins. Although they are a happy brood, the arrival of the twins seems to act as a catalyst, emphasizing whatever potential problems they have. The baby of the family becomes even more babyish; the oldest girl becomes a goody goody; one boy becomes a rebel, while a middle child feels particularly neglected. Ruling over the family is Miss Thorp who even further aggravates the situation until with love and understanding the family adjusts, happy at last, acceptant that they are now an eight-child household. A somewhat sentimental story in which the author pleasantly capitalizes on the large family, basing her plot more on the personalities of the children than on action or event.
