Spooky Advent: 8th December

Dark Matter by Michelle Paver. Creeping horror in the far North set in the 1930s. Jack, a working class lad, gets the opportunity to join an Arctic expedition to the North East Coast of Svalbard. After a medical emergency he is left alone at the camp, and everything begins to deteriorate - the weather, the equipment, Jack's mental health, as the winter sun disappears completely and he begins to have visions of what may or may not be the vengeful ghost of a man who was killed there.
