17 year old Sally Rockwell's baby brother Larry Joe, who was born on the eve of her graduation dance, turns out to be Mongoloid. The family ignores their physician's advice to keep the baby in a home and not to see him at all. Sally, however, develops an interest in retarded children, she visits a camp for the handicapped and chooses as her serority pledging project to work in a school for educable children. Her first-hand knowledge of the problem helps her to fight off the prejudices of her neighbors and to convince her parents that Larry Joe should be cared for at home. The story tends to bog down around the drawn out descriptions of Sally's pledging activities and of the shocked reactions of her prejudiced housemother who is as opposed to the retarded as she is to foreigners. Her attitude, which is shared by most of the Rockwells, presumably progressive New England community, is unnecessarily exaggerated. There is a good deal of information about Mongoloids and how they can be helped, which makes this book potentially interesting to anyone with a limited knowledge about retardation, but its impact is weakened by the writing.
