OutTack, FarTack, HomeTack -- novels by GS Boughton in the DeepStorm trilogy
As OutTack opens, the world is beginning to experience the first tremors of the calamity reported on the Georama news channel. The UN meets around the clock in a desperate bid to devise a survival strategy, unrest mounts, military forces struggle to maintain order, and aid agencies gamely attempt to prepare citizens everywhere for the threat that lies ahead. Helplessly they look on as mankind's foothold on Earth, the Moon and Mars is relentlessly undermined by DeepStorm. All eyes are on the night sky, where it is known that a phenomenon is fast approaching through the Solar System to deal death and destruction everywhere.
