THIS is the winner of the Red Book-Dodd, Mead $10,000 Prize Novel Competition, and so is worth respectful consideration by any reader. It is the story of a family divided by divorce, leaving an intense, unhappy young girl to look after an almost imbecile, good-natured mother. To them summering on the Maine Coast comes the mother’s sister, a young widow with four sons. Hildreth’s half-unrealized love for a young, proud, poor young man, Geoff, runs into grave complications. The characters are well drawn, several of them remarkably so. The story has a slight tendency to drag, owing to the author’s preoccupation with her characters as against incident. It is, however, a well-achieved novel, even it if is not a great one.
