The education of the blind is given a thorough scrutiny in this story about a boy in his Junior year of high school who loses his sight as the result of an accident. The physical and some of the mental stumbling blocks that must be overcome, and the process by which this is accomplished are particularly well described. Following a summer of reconciliation to his new ambition, Mark begins his next school year at a boarding school for the blind. He is determined to become as independent as possible and his rigorous training is geared toward that end. Living at the school he must adjust both to the new curriculum and to the separate and sometimes variant obstacles posed by the other students. On a personal, level, he manages to continue as a ham radio operator and with his electronic experiments, and to regain some of his skill as a sprinter (his injury had occurred during a sprinting match). Whenever Mark is described in any respect other then his blindness, he turns into a fictional nonentity; His hatred of the boy who had caused his fall is never resolved, his problem with a jealous, ambitious roommate is left dangling, his romance with a blind girl progresses too far, too fast, too smoothly. Then too, it is annoying to discover continually that except for his handicap the boy is without blemish, especially when he caps his success by rescuing some children from a fire. Since the book is quite long, these details seem like unnecessary embroidery to an interesting subject.
