Now THIS was a Larry Niven book out of the Known Space series that was pretty good. I wasn't quite sure where it was headed, and it certainly ended weird. But you could feel the influence of other Larry Niven stories and ideas, but set in their own world. As he said at the beginning, it was also well-edited: "...where the hell were you for Ringworld? If you own a first printing, it's rare. It's my only story where the Earth turns the wrong way!"
