THAT summer when Sudy and Prill met and became best friends was an important one for both girls. To Sudy, an only child, new to the little New England coast town, Prill's big, musical, very merry family was the complete realization of a lonesome girl's dreams. She didn't know that Prill often felt left out of her own family's group, nor guess the secret hurt that made Prill feel thus. Sudy had her own hidden problem too, an ever deepening sense that she wasn't brave enough to live up to her father's standards. This isn't a problem story. It is full of good times and small adventures, but the way in which each girl solved her difficulty, unconsciously spurred on by her affection for the other, brings this narrative of a true friendship to a very satisfying conclusion.
