For fiction based on astronomy this offers a less lurid story than the usual science fiction and turns out to be a good yarn with some dignity. 1960 is marked by strange happenings throughout the world for which Russia is blamed and war is a question of minutes. At Palemar, Dr. Dawson, checked by internationally famous astronomers, announces the coming of a new planet -- Y -- which will overtake the earth and end the world in 1962 at Christmas. The story of how our universe adjusts to the idea, of how peace becomes, for a little while, permanent, and prosperity, global good will and christian living come into their own, packs a surprise finish of some moral interest. A relief from the pulps.
