Outside
(Book)

"Four friends. One night. Not everyone will come out alive . . . When a deadly snowstorm strikes the Icelandic highlands, four friends seek shelter in a small, abandoned hunting lodge. It is in the middle of nowhere and there's no way of communicating with the outside world. They are isolated, but they are not alone . . . As the night darkens, and fears intensify, an old tragedy gradually surfaces - one that forever changed the course of their friendship. Those dark memories could hold the key to the mystery the friends now find themselves in. And whether they will survive until morning . . . "--publisher's website.
