The novel interweaves two realities (or is it only one?) in an intriguing way that builds towards a climax that neatly encapsulates the paranoia of terrorism that is increasingly becoming a feature of our modern society . The ending will make you smile in a rather cynical way - not at any shortcomings with the story though. Rather at the way it so aptly captures the way in which politicians in recent years have played the 'fear' card, as it were, to justify increased surveillance and other strategies that erode traditional freedoms. It may not be a classic but its a good read.
