 As dated in the 1959 version of de Camp's essay "The Krishna Stories" and James Cambias's "GURPS Planet Krishna" (a 1997 gaming guide to the "Viagens" series authorized by de Camp), the Krishnan events of "The Queen of Zamba" take place in the year 2138, falling between "Perpetual Motion" and "Calories", and making it the third story set on Krishna in terms of chronology.The primary portion of the story is preceded and followed by scenes on Earth, each of which is over a decade removed from the main action.Early reviewers of the Ace edition were not terribly impressed by the book.
