William Day should be an acclaimed Arctic explorer. But after a failed expedition, in which his remaining men only survived by eating their dead comrades, he returned in disgrace. Thirteen years later, his second-in-command, Jesse Stevens, has gone missing in the same frozen waters. Perhaps this is Day’s chance to restore his tarnished reputation by bringing Stevens --- the man who’s haunted his whole life --- back home. But when the rescue mission becomes an uncanny journey into his past, Day must face up to the things he’s done. Aboard ship, Day also must contend with unwanted passengers. Following a trail of cryptic messages, gaunt bodies and old bones, their search becomes more and more unnerving, as it becomes clear that the restless dead are never far behind.

In the wake of the First World War, Jonathan Morgan stows away on an Antarctic expedition, determined to find his rightful place in the world of men. But not all is smooth sailing: the war casts its long shadow over them all, and grief, guilt and mistrust skulk among the explorers. When disaster strikes in Antarctica’s frozen Weddell Sea, the men must take to the land. In the freezing darkness of the Polar night, where the aurora creeps across the sky, something terrible has been waiting to lure them out into its deadly landscape. As the harsh Antarctic winter descends, this supernatural force will prey on their deepest desires and deepest fears to pick them off one by one.
