It's winter 1947 when newlyweds Ellen and Tony Wylde move into an abandoned Cornish farmhouse overlooking the sea. For both, it's a new beginning in the country, and together they're bringing Carreg Cottage back to life. Yet Ellen can't hide a creeping unease. There's the ominous iconography painted on their bedroom ceiling, the sinister doll hidden away in the chimney. And Tony seems more familiar with the peculiar villagers than he's letting on.

Meanwhile, after nearly a decade away, young Iris returns to Cornwall seeking sanctuary in memories and longing for what she lost as a child. It was here that her mother died on the moors under a shroud of mystery and rumor--and was last seen alive in the isolated, long-shuttered cottage the Wyldes now call home.

Discovering more about each other and themselves, Ellen and Iris soon unite in a quest to uncover every dark secret this village--and the West Country mist--holds before it destroys them.
