A sincere attempt to portray tough family problems -- remarriage and the consequent jealousy, is the mainstream of popular Janet Lambert's latest book- which is still a bit too shiny and starry-eyed for our tastes. When 15 year old Paula Marsh, comes to visit her relatives the Hollisters, a big happy family in the East, there is a chip on her shoulder, for her mother has just gone off to Europe with a new husband. From the start it is Cinda Hollister, a year younger but an extrovert, who draws her out by asking artless questions and forcing Paula to answer both to herself and her family for the unreasonable jealousy of her mother's new love which has so far been interpreted as rejection. With the Hollisters, Marsha summer vacations in New England and the weeks of boys, good times and Cinda's own growing pains, prepare her for her mother's return with Daddy Fred and a new family solidarity. Right morals but facile solutions and the veneer of glamour which seems to cover little intellect dulls the edge.
