The time is just a few short years from now. But already the signs of global disaster are multiplying. Freak storms, earthquakes, floods volcanic eruptions are sweeping the earth. The last violent spasms of a dying planet.

Then a series of ominous events signal the emergence of new and terrifying forces. While scuba-diving on the Great Barrier Reef a diver watches fascinated as a tiny light floats past him towards the surface. Moments later he is torn to pieces as the reef erupts with shattering power. In the Chinese city of Kashi travellers bring back reports of a strange light seen shining above the endless dunes of the Taklimakan Desert. And as the city's inhabitants watch for its return the desert rises up like a vast living thing to engulf them in a colossal tidal wave of sand.

All have seen a portent. A sign of unimaginable powers about to be unleashed. A sign that something incredible is about to begin.
