Elinor Golden has had trouble reading and writing ever since a golf ball hit her in the head as a child and left her with permanent minor brain damage. Otherwise quite intelligent and fully functional, she has stumbled through school unable to perform assigned tasks, unwilling to make the nature of her problem any more public than she has to, and often alone with it, since few teachers, even those who know the problem, know how to help her. Even her father, a doctor, is baffled.

It is 1943 and, as the U.S. enters the war, her attention is diverted to problems bigger than her own. She joins a volunteer corps that keeps watch for enemy planes approaching the New England coast. In the course of this purposeful work, she is paired on watch with a young teacher who finds a way to help her read by having her trace letters with her finger. Both her new work and her new reading strategy empower her, and help her cope with the crisis of her parents' separation and the departure of her lifelong friend, Jed, for Dartmouth.

She leaves school and joins a group of paid volunteers to do war work, discovering new areas of competency and satisfaction after years of feeling like a failure. At the same time her friend, Jed, discovers something new in her, and friendship turns to romance as personal hope blossoms in the midst of trouble and war.
