Synopsis: From the front flap Severn US edition: "Creatures from a glacial hell, the whites of their eyes bulged red with bloodlust... When American scientist Tony Stevens hears that his young sister has been killed in a skiing accident in Oslo, he refuses to believe it. She hated heights, would never risk descending the treacherous glacier slopes so rapidly - unless she was fleeing for her life... On arriving in Norway, he learns that Ann had been working with an archaeology team excavating a preChristian burial site in the frozen wildness of Trolltinder. Something terrible has been disturbed - surrounding villages are in uproar, fear and superstition cloud the air like a mist of chilling malevolence. And Tony realises that whatever it is out there that devoured his sister has picked up his scent, and is poised to wreak its ancient, inhumanly agonising vengeance once again..."
