Z for Zachariah by Robert C. O'Brien verges on science fiction. A young girl, apparently the last survivor of an atomic war, has been miraculously saved from radiation sickness in a hidden valley in the U.S. Her peace is broken by the intrusion of a man, a scientist who suffers from hallucinations or perhaps from memories of some wicked deed in the past. Efforts of joint survival go sour; the man becomes very peculiar indeed and the girl is forced to take direct action. The suspense is beautifully handles, frightening and all too realistic; the ending is inconclusive and all the better for that.
Zachariah Robert's immediate neighbors in , are 24 individuals in 9 households.
