I read this book originally back in the 1970s and hadn't realized that I had read it before until I was well into the current reread. I have always liked Heinlein and probably liked this one when I first read it, but I have to say that this novel didn't hold up very well for me. It's kind of a mishmash between fantasy and science fiction and borrows heavily from Edgar Rice Burroughs and Tolkien. The story is pretty outlandish and Heinlein views on sex and politics dominate the theme of the book. He denounces democracy and considers women to be like cats - when they want affection, you better give it to them, if not, leave them alone. Overall, I would recommend rereading one of Burroughs Mars stories rather than reading this drivel again!
