This is the 26th book of 29 to date in the length "Gorean saga" of novels, set mostly on the planet Gor, an artificial and beautiful earthlike world which supposedly shares the orbit of Earth but on the opposite side of the sun so that our astronomers cannot detect it.
If you have read all 25 of the previous Gor books (in which case you will probably read this one whatever the reviews say) you will get something out of "Witness of Gor".
If you have not read at least most of the previous books in John Norman's Gor series, do not touch this one with the proverbial barge-pole.
The story is set mostly in the Gorean city of Treve, and appears to overlap several of the previous five books. Tarl Cabot, central character of most of the books in this series, does not directly appear in this book at any point, though he is mentioned once or twice. The narrator is a slave girl from earth, who at various times of the book is given the names Janice or Gail, or at other times is not allowed a name at all.
The narrator has been planted in Treve in the hope that she will be able to identify whether a particular important prisoner is there. She has no idea who the prisoner is, and when she does find him, he appears to have lost his memory and doesn't know himself. Norman obviously intends the reader to work out the prisoner's identity for yourself: he is not named at any stage in this book and therefore I won't name him to avoid spoiling the story. Those readers who have previously seen the rest of the series may begin to form an idea what is going on. The reader will learn from the 29th book, "Swordsmen of Gor," the identify of the prisoner and what happens when he finally recovers his memory.
There are some quite good parts of the book: one is the development of the pit master character, who is horribly ugly but also honourable and intelligent and about as kind as Norman allows a Gorean male to be (which after about book eight has meant "not very"). You meet again an old enemy, Doorna the Proud, who attempted to usurp the throne of the city of Tharna in book two, "Outlaw of Gor". Naturally she has never forgiven Tarl Cabot for frustrating her ambitions, and Norman may be setting up something here for a future book.
The most nerve-wracking scene comes towards the end of the book when an entire hit squad of assassins comes to dispose of the prisoner, only to find that he is still much more dangerous than anyone had imagined.
No mention at all of the alien Kurri or "Others" in this book - those of us who have been wondering to what extent they were behind the attack on Ar by the island kingdom of Cos, and the subsequent war which raged from book 20 to book 25 will not learn anything from "Witness of Gor." In fact, although the humans who brought the central character of this book from Earth to Gor must have been working for one of two alien races - the Priest Kings or the Kurri - they do not share this information with her. As the narrator never discovers that she was taken from Earth on an alien-built ship, the reader does not find out which alien race was involved.
The narrator of this story will make a brief cameo appearance in the subsequent book "Prize of Gor." She will meet the narrator of that book in the city of Ar, when both slave girls will have been sent by their respective masters to Ar's equivalent of the public laundrette to wash their household's dirty clothes. By that time Gail/Janice will have been renamed yet again by her new master and be known as Corinne.

Books with (K) at the end of the description are "Kajira" novels, e.g. they are stories like this one, told from the perspective of slave girls, (Kajira is Gorean for slave girl.) Books 14 to 16 are told in the first person by a man from earth called Jason Marshall and tell his story. All other books have Tarl Cabot as the central character.
Norman's greatest strength is not that he is a particularly good writer, and the prose in this work is sometimes quite impenetrable. His strength is his ability to set your own imagination off, and at times this book does do that.
The catch is that to get to those moments you have to wade through reams of very undistinguished filler, and particularly the most turgid "women should be slaves" tosh. The very apposite title to one of the reviews of this book on the Amazon US site is "Why did the Pit Master want to throw himself into the abyss? Because he was forced to read the first 400 pages of 'Witness of Gor'!"
It is one thing to fantasise about things which you would never want to do in your real life, but the endless repetition of arguments for enslaving women eventually gets quite boring and almost makes you wonder if Norman actually means it. There was rather too much material of this kind in books 14 to 25, and Witness of Gor is worse. From this 700 page book you could cut out at least 250 pages of male supremacist lectures without losing any of the essential plot or action, and still have quite enough left to annoy any feminists or politically correct people who for some strange reason are reading it. And it would be a much better book.
