What would have made the book successful is if it had either a) allowed the revolution to progress far enough that the narrator was genuinely outside the system, or b) had the narrator show awareness that her revolution was incomplete. As it was, the narrator (and, perhaps, the author) close the book as though the story is done, which is really unsatisfying -- it ignores the actual state of things and pretends there's been a climax, when in fact we're still in rising action.
