Tarnsman of Gor - John Norman (Gorean Saga, Bk. 1)

Well, this certainly doesn't pass the Bechdel test, but I knew that going in based on the lore that made me curious to read this book to begin with.  Rampant sexism aside:

It was slow to start, but once the main character gets his footing in the new world, the action flows quite well.  I did not like the authors use of "lucky circumstance".  It was too heavy and far too convenient in the plot line instead of forcing the character to think/work his way out of the problems he got into.  The author does, however, do a good job of not over-explaining.  He leaves enough myth and mystery that I am curious to read the next book.
