["Star Rangers" is] an imaginative and moving historical novel. This is a historical novel of the collapse of a decadent Galactic Empire; but it obtains its powerful effect by restricting its action to a small area of the surface of one planet and to the problems of a group of spacemen, abandoned by the empire they had lived only to serve. No cut-and-dried star hopping here, but oddly all the more impact of the awe and wonder of space—as the ocean may have more meaning to a castaway than to a trans-oceanic plane passenger. The plot involves a surprise that should not be mentioned here—an old theme, but one I've never seen so well handled before. In all, an excellent book for the new science fiction reader, and even for the veteran a refreshingly readable one. (p. 9)
