I see why this made it to last year's Man Booker Longlist now. The writing is subtle and powerful, creating a gloomy atmosphere a little bit at a time, letting your imagination fall slowly into the endless dark of an Arctic night.
Then, when you are alone in the dark and the deadly cold, introducing a sensation of dread that is nameless only because you don't dare name it because naming it would make it real.
I've just read a passage about a man getting lost in fog on Halloween night, a short distance from the cabin he can no longer see. Nothing happened. Probably. Yet it the passage held more fear in it than any confrontation with a monster could have produced.
