By the time we get to "Guardsman of Gor," the 15th of John Norman's Counter-Earth novels, we are clearly in a transitional period. I did not like the idea that instead of Tarl Cabot we were now telling the story of a different Earth man who ends up on Gor, although the Jason Marshall trilogy was more interesting to me than the story of Judy Thornton, a woman brought to Gor as a captive in "Slave Girl of Gor." In the first volume of the trilogy, "Fighting Slave of Gor," Marshall ends up on Gor when he tries to save Beverly Henderson from a Gorean slave trap. The next thing the civilized Earth man knows he is a slave on Gor. Starting out as the silk slave of the Lady Florence of Vonda, Marshall then becomes a Gorean gladiator, which gives him the opportunity to become free so that he can find Beverly, who now also a slave on Gor.
"Rogue of Gor" is the middle volume in the trilogy and the novel and has Marshall searching for Beverly. But since this is a trilogy you know that he is not going to find her until the final volume, "Guardsman of Gor." Instead, Marshall travels along the River Vosk to the port city of Victoria, north of Port Kar, and finds himself in the middle of a war between Glorious Ar and the Salerian Confederation as the pirate fleet seeks to control the waterways of Gor on which the cities are so dependent. In terms of providing more action than sex, this is the one volume of the trilogy that delivers on that score and if you are waiting for Jason and Beverly to consummate their relationship in Gorean terms you have the last half of the next novel for all of that to play out (after a giant naval battle). In this one he finds her on the slaver's block, buys her, and sets her free even though she insists she is a true slave and therefore does not desire freedom.
There is a sense in which Norman is trying to get back to the basics, since the fight between Ar and the Salerian Confederation is not, at face value, part of the gigantic struggle between the Priest-Kings and the Kurii. But the sexual philosophy of Gor is now becoming the dominant theme of Norman's stories. The back of the original paperback declares, "Jason Marshall learned the meaning of manhood and the power of women, both dominant and submissive" on Gor, but clearly he has yet to fully accept his role in this society. This time around Norman is educating a male rather than a female, which is usually the case in the Gor novels, and I think that you have to take such instruction at face value.
The obvious assumption might be that most men would not need to be persuaded to live a life being a master, but when you consider the discussion that Jason and Beverly were having at the start of the trilogy before they ended up on Gor you have to admit that it is not exactly the sort of lifestyle to which a "civilized" man would aspire. Clearly Norman is arguing men have to be carefully taught such beliefs almost as much as women, although you will never convince me the male of the species would require as much persuasion. Consequently, whether you judge "Rogue of Gor" by the standard of either the best Gor adventures ("Nomads of Gor" and "Assassins of Gor") or the main testaments of Gorean sexuality ("Slave Girl of Gor," "Kajira of Gor," and "Dancing Girl of Gor"), it falls short. For the most part only true believers are going to proceed beyond this trilogy to complete the series.
