This is the most DIFFERENT Sci-fi book that I have ever read or conceived of, and I'm not sure whether I like it or not – furthermore, I can't assess whether it's any good :-(. Okay, let's just look at it from the review perspective. It certainly starts out as a normal mystery, and the sci-fi aspect really doesn't appear until near the end – well, halfway through, anyway. It may just be my belief in reliance on reality that's tripping me up, but I do enjoy sci-fi/fantasy books frequently without the need for reality or the truth of our world. Maybe the problem is the illusion of our world and reality, and I just don't deal with change of world and reality on the fly. Maybe that's an indication that I'm "close minded", but I really don't like to believe that.
For the most part, it actually was a good book, and it forced the reader to bend beliefs change hes views of the possibilities of the world.
