This book is a real slap! At the beginning its quite difficult to get into the story (the beginning 30p) on a love story between a university professor and a girl a bit lost, it then enters the heart of the matter: the activities of an extremist revolutionary group. Capitalism exacerbated, citizens with grades, ranking the "merit", social determinism, eugenics ... many themes are about the colony located on a Saturn's sattellite. Earth has been ravaged by biological weapons. This book awakens the citizen in you, it makes you sign up for the causes that are important to you, thanks to a free pen, spirited, optimistic. The style is beautiful, superb verbal jousting, bold ideas, icy concepts so topical. Read This! ( )
