Tension--more taut than in most juveniles--builds from the moment that Gail (fifteen), hiking alone, sees the car-stricken deer and the bright eyes of the young driver see her. The boy, Lew, follows her, giving her several explanations why he does, alibiing his nervous behavior. Gail's initial trust and liking, even attraction to him is shocked by the sight of a gun in his pocket, the sudden realization that he is the ruthless bank robber at large, that he wants to kill her for what she saw. A terrifying life and death chase over the mountain ends when the two are trapped high on a fire tower--one well-placed kick topples him, and Gail is found warming the broken body breathing its last. The author's skill at portraying and eliciting fear, at setting up an intriguing relationship, is undermined by her insistence on constant exposition and explanation, by her trite tying up of ends at the finish, by her facile, shallow characterizations. But non-stop reading for non-readers.
