I really do not find in this novel a masterpiece which was recommended by several sources. To me, this book uses science fiction themes to convey an anthropological exploration of banal story much too human (in the sense that the exoplanet is almost similar to Earth, where aliens have thought patterns identical to land (just one (of) company (s) a bit special (s))) and end on a key human this time we would like in the psychological sense, but that has nothing to interesting.
