Photographer Isla Wilson is thrilled she’s landed her dream job, but the clients who hired her are getting stranger by the day.

It sounded so perfect - a month‘s assignment at the misty, sprawling Scottish Highlands property of brilliant architect Alban McGregor, and his wife, Jessica.

But deep in the woods, there is a chilling playhouse.
Two years ago, the McGregors’ daughter, Elodie, died after being abducted and taken there. Alban refuses to knock the playhouse down, and he keeps a picture of it on his wall.

Isla senses that both Alban and Jessica are keeping terrible secrets.
The closer Isla comes to getting answers about Elodie, the more the danger mounts. And with a dense cover of snow now blanketing the town, all chance of escape might already be gone.
