The new thriller from Dean Koontz is a novel of surpassing suspense and visceral terror as doomsday dawns. On the morning that will mark the end of the world they have known, Molly and Niel Sloan awaken to the drumbeat of rain. It has haunted their dreams through the night, and now they find an eerily luminous and golden downpour that drenches their small Californian mountain town. As hours pass they hear news of extreme weather phenomena across the globe. An obscuring fog turns once familiar streets into a ghostly labyrinth. By evening, the town has lost all communication with the outside world. First TV and radio go dead, then the Internet and phone lines. The young couple gathers together with some neighbours, sensing a threat they cannot identify or even imagine. The night brings strange noises, and mysterious lights drift among the trees. The rain diminishes with the dawn but a moody grey-purple twilight prevails. Within the misty gloom the small band will encounter something that reveals in a terrifying instant what is happening to the world -- something that is hunting them with ruthless efficiency.
