It’s been three years since Hallie and Gertie’s brother Pete vanished on Tasmania’s Mount Mercy; three years during which Hallie and Gertie haven’t spoken to each other. Their dying mother issues one last request: that the sisters get down to Tasmania and do what the police and SES couldn’t, and find out what happened to Pete, who was last seen at an isolated commune on the face of the mountain.

As soon as they arrive at the town of Pine Peak, near Mount Mercy, they hear the rumours everywhere: that the mountain claims people. Whatever lies beyond those trees is dangerous, and Pete isn’t the first or the last person to go missing there. The two sisters, with years of bitterness and trauma between them, will go up there anyway – but there’s no guarantee either will return. Utterly chilling (and it is Tasmania, so I mean that in both its terror and temperature definitions) and tense, this is a perfect winter thriller.
