Planes falling out of the sky with tremendous loss of life, a new drug causing people to display great strength, but also great rage, and a terrorist with an incredibly strong grudge. All this adds up to an extremely difficult situation for Sam Archer and all his colleagues whether in the USA or England, not knowing where the next strike might be.
At fist I thought that this was going a little over the top, but as the tension, and the explanations, developed, it became a very taut story with many last minute twists, whether at sea, at an airport, or in the air. Tunnels form an integral part of the story, some in USA and Mexico, others in France.
It became a book that I wanted to finish and could not put down. The plot behind it all is a very complex one, but one that could just possibly take place.
