A holiday in the Highlands turns into a hostile trap in this vicious thriller about a family who will stop at nothing to keep their dark past buried.

In this family, some secrets are worth killing for.

When Patrick accompanies his girlfriend, Holly Grant, to a remote village in the Scottish Highlands for the holidays, he's braced for an awkward first meeting with her enigmatic family-not a fight for survival.

But tensions are high among the Grant siblings, all of whom are unsettled by the arrival of their father's much younger fiancée, Jasmine, who bears an uncanny resemblance to their late mother. As suspicion and paranoia grip the household, Patrick is drawn into a sinister plot involving the Grant family, Jasmine and the frozen corpse of a young man found in a nearby cave.

With the clock ticking towards New Year's Eve, Patrick finds himself in a den of vipers, unsure of who he can trust and who is poised to strike with lethal precision.

From the mind of Mark Edwards, whom Lisa Jewell says "is in a league of his own," comes a venomous thriller about the lengths one family will go to conceal their darkest secrets.
