The common theme in all these narratives is the search for identity by memory. Each character is assigned a psychological defect that makes him see things his way and deeply affects his quest for me. The main protagonist, Richard Grey, has become amnesiac following the attack which he suffered. He remembers nothing of weeks before the attack. So logically it proceed by paramnesia to rebuild, that is to say, his memories are nothing more than fabrications within its own imagination. Kewley Susan, her friend, who carries within her the gift or curse called glamor, is mostly invisible physically, socially and thus erased. This feeling makes erase, to her as to all the "glam" (carriers of glamor), more or less paranoid and schizophrenic. She said also persecuted by another glam, Niall, who through jealousy rots it literally his emotional life by interfering slyly into it. It will try, despite these difficulties, help Richard to rebuild instilling his own memories.
Roman for several voices built to put constantly undermined our common sense, Glamour is probably the most complex book by Christopher Priest, as it pushes to the extreme one of the favorite themes of the author, which is the constant questioning of reality through play divergent perspectives. As in many other of his works (The petrifying fountain, Separation, interior Future Archipelago dream) the psychological dimension occupies a prominent place.
Therefore an important book, but I advise foremost connoisseurs of Priest. For others rather start reading the novels cited above, that are most appropriate for my taste to become familiar with the author.
