A sequel to a book we'll meet later. Reviews:
Groff Conklin described the 1952 edition as "a fascinating book . . . despite its bombast and its blithe impossibilities." Boucher and McComas described the novel as "a grand fantasy-melodrama," although they questioned "whether its noble imaginative adventure has anything to do with science fiction."
Usual internicene squabbles. C'mon! Look at the cover. Tanks shooting energy beams, spaceships, futuristic buildings - how can it not be science fiction?
The cover wouldn't oversell the thing, would it?
