In a mountainous region of the Scottish Highlands, a young woman's body has been found on a remote stretch of road. Though the manner of her death suggests a terrible accident, a name carved into her arm hints at something more sinister.

And when a personal connection to the name is revealed, DIs Georgina Lennox and Richard Stewart are sent to investigate.

As George and Richie question locals, they discover that the road has a bloody history. Fearing that more women will be harmed, they track the killer through a rugged wilderness where ancient feuds, generational curses and the unforgiving elements fight for supremacy.

But there are more secrets to the road than just its history - and the people living along it will do whatever it takes to stop those secrets from coming out.
