Midge, a junior at a fashionable boarding school, fears an uneventful summer at her home in Long Island. But her cousin Debby's broken romance with a young minister, an inherited house in Mount Kisco, her self-centered older sister, and her myriad friends, turn Midge's summer into a kaleidoscope of adventure in which she not only is diverted but comes face to face with herself and her values. Mide is a ""good"" girl with just a touch of mischief to add piquancy. And though she has some bad moments, they only sharpen the happiness which inevitably awaits such ""good"" young girls of fiction. The whole, hopeful summer is topped off with a gorgeous wedding at the end, an icing to this cake which though it does not nourish guarantees to sweeten the palate of the less mature adolescent.
