EVERYONE IS IN DANGER. ANYONE COULD BE NEXT.

An imposing, isolated hotel high in the Swiss Alps is the last place Elin Warner wants to be. But she's taken a sabbatical from her job as a detective, so when she suddenly receives an invitation to celebrate her estranged brother's recent engagement, she has no choice but to accept.

As Elin arrives in the midst of a threatening storm, she immediately feels on edge. Although it's beautiful, something about the hotel, recently converted from an abandoned sanatorium, makes her nervous - and her brother Isaac.

And when they wake up the next morning to find his fiancée Laura has disappeared without a trace, Elin is even more concerned. As the storm cuts off access to and from the hotel, the longer Laura remains missing, the more the remaining guests begin to panic.

But no one has yet realised that another woman has gone missing. And she is the only one who could have warned them about the danger they are all in...
