The action takes place in the late 21th century on an asteroid near Saturn, in a city named Cerclon I. Without taking risks, we can already say that this settlement will not happen anytime soon, and that the author, Alain Damasio, is well aware. This "gap" unrealistic is not a problem, as the conquest of space is not the theme of the book. And to my dismay, that is about the only improbability ... Moreover we can not still read "1984" by George Orwell, without greatly benefit? It is more for Damasio create a context for thought experiments. The book deals primarily a system of governance that we all think we know: democracy. I Cerclon claims to a democracy, and it is true that every citizen expresses its will by voting. But "we" can play insidiously about what it means to want or believe the people ..... and I leave you the pleasure to discover all that I tried not to tell in this comment. Those who, like me, have greatly enjoyed "the horde of shutter" the same author can order without hesitation. The pen, you could check both freedom and dexterity, soaked in the same inkwell. I personally think that we will one day the works of Damasio among the lists of "essential" or "classic". But I leave you free intelligence to judge for itself.
