By Alan Dean Foster
A team of scientists have arrived to explore the virgin world of Xica, an earthlike planet with oceans, continents, plants and animal life. Their mission is to collect specimens and study them. They set up base camp and are enthralled with the alien creatures they discover. But they are even more enthralled when they find a village of attractive humanoids who seem harmless and friendly. These people have a stone-age technology and are eager to learn about the Earth people and they are eager to improve themselves. So scientists and the natives are spending a lot of time together and getting along fairly well when the scientists are amazed and dismayed to discover that they are not the first humans to land on Xica. A man from Earth has been on the planet for decades, and according to him, Old Con, he pretty much taught the natives everything they know. The scientists are upset that he has contaminated the natives with his knowledge. Once Old Con is part of the story, everything goes from good to bad to awful.
This is a pretty superficial look at humans encountering a primitive alien culture. We don't get to know the scientists or the aliens very well, not even Old Con, who is portrayed as some kind of superman without it explaining how he got that way other than the school of hard knocks. So when the author kills off most of the humans, it doesn't mean much at all since we really don't get to know most of them. The team includes three female scientists, and we are told several times that they are gorgeous, but then the author never does much with that information. All in all, a rather unsatisfactory novel.
