Something terrible has happened in the snowbound village of Kingdom Come, Wyoming, where twelve eerily identical houses stand dark and abandoned. Meals remain untouched on dining room tables, cars are still in garages, and the town's residents have vanished into thin air. This is the disturbing setting where vacationing medical examiner Maura Isles and her traveling companions find themselves trapped during a ferocious snowstorm. Thinking they've found a safe haven, they soon realize that they are not alone in the valley....someone is watching.
