ISBN Unwanted Guest

We can't choose the strangers we meet.
As the guests arrive at beautiful, remote Mitchell's Inn, they're all looking forward to a relaxing weekend deep in the forest, miles from anywhere. They watch their fellow guests with interest, from a polite distance.
Usually we can avoid the people who make us nervous, make us afraid.
With a violent storm raging, the group finds itself completely cut off from the outside world. Nobody can get in - or out. And then the first body is found . . . and the horrifying truth comes to light. There's a killer among them - and nowhere to run.
Until we find ourselves in a situation we can't escape. Trapped.
