Molly and Neil Sloan wake to find an eerily luminous downpour drenching their small Californian mountain town. As the rain continues to fall, TV pictures relay disturbing news of extreme weather phenomena across the globe. With the evening comes a ghostly fog. Their sense of isolation is complete when first TV and radio, then the internet and phone lines go dead. Molly and Neil gather with neighbours, sensing an awful danger approaching with the night... It's like a scary movie made real. But what is really happening? Is it science gone wrong or a technology beyond human understanding? Or something deeper, more fundamental. Something to do with fate and purpose.
