A girl discovers a ghostly mystery when her family take a caravan holiday on the coast of Wales.
Lark needs a break. Her mother is ill, her sister has stopped speaking and she's fallen out with her best friend. When her family arrives at a caravan park on the Welsh coast, Lark and her little sister rush off to explore.
But soon this freedom gets frightening. Is there a figure in the fog? What happened at the ruined house in the woods? Why is her sister so fascinated by a girl in a green dress?
As the storm gets wilder and events get stranger, Lark must face a long-buried secret to try to save her family.
