This is not your typical Sci-fi book. If you are not familiar with the “Culture” Series by Iain M. Banks then you probably won’t even notice the science fiction that is going on behind the scenes. If you are familiar with the series then, like me, you will probably find this book simply brilliant. “Culture” often meddles with less advanced worlds, helping them evolve into a more advanced civilization.
Since the story is told from the point of view of person from the less advanced world there is no direct mention of the real story, because “culture” helps without the people they are helping having any knowledge.
If you are not familiar with “Culture”, you still get a get an enjoyable story (but will miss the sci-fi aspect of the story). If you are familiar with the “culture series”. You get 2 stories, the one that is told and the one that your insight will allow you see. Brilliant!
