Dark Matter by Michelle Paver

January, 1937. Twenty-eight-year-old Jack is poor, lonely and desperate to change his life. So when he’s offered the chance to be the wireless operator on an Arctic expedition, he jumps at it. Five men and eight huskies, cross the Barents Sea from Norway by the light of the midnight sun. At last they reach the remote, uninhabited bay where they will camp. Gruhuken. But the Arctic summer is brief. As night returns to claim the land, Jack feels a creeping unease. One by one, his companions are forced to leave. He has to decide, stay or go. Soon he will see the last of the sun, the point of no return – when the sea will freeze. And Gruhuken is not uninhabited. Something walks there in the dark.
