The neurolinguistic aspects of the story hark back to Neal Stephenson's brilliant Snow Crash, but this is a very different beast. Absent the futuristic dystopia, any reference to a cyberpunk like "cyberspace", this is a novel set very much in "contemporary" times with contemporary technology.
Absent too is much of the wry humour of Stephenson's Snow Crash, making this a much darker and far more brutal novel than the former.
That said, it is a thought provoking page-turner that grabs the reader with the initial questions and doesn't let go, dragging us through an adrenaline filled present interspaced with chapters of a fascinating past, and challenging us to guess how we got here from there - until all threads are tidily, and satisfactorily, resolved in the climax and denouement.
There is great tragedy in what is in some ways an epic, blood-stained love story, contrasted against another, very sad one.
In short, brilliant. Read it.
