A thrilling new novel from the author of The Girl Without Skin. When Danish Journalist Matthew Cave’s half-sister Arnaq disappears, leaving behind only a trail of blood, he realises they are both pawns in a game of life and death. As a young US soldier stationed in Greenland, their father took part in a secret experiment with deadly consequences. Accused of murder, he was forced into hiding. Desperate to discover the link between these two disappearances, Matthew is joined by Tupaarnaq, a young Inuit woman, who returns to Nuuk to help her only friend—and to settle a few scores of her own. But, as things begin to unravel, Matthew begins to wonder: Is the father he has been searching for his entire life actually a cold-blooded murderer? And is Tupaarnaq really who he thinks she is?
