I´ve read five books of this author, The separation, Inverted World, The afirmation, The prestige and Dream Archipielago. This man is really incredible, I think is the most intelligent writter of sci-fi I´ve ever read. He doesn´t write typical sci-fi (Are The afirmation and The separation sci-fi?), but he´s so good, I don´t matter. What´s your opinion?
