The Sentinel

An angry clash between professional whale hunters and the environmental activists out to stop them takes a deadly turn when sabotage sends both vessels to the bottom of the Arctic Ocean. Stranded in the aftermath on a desolate island off the coast of Greenland, survivors from both sides reluctantly join forces to stay alive in the frigid wasteland. But they swiftly discover that those who perished in the unforgiving sea were the lucky ones... Jane Harper, an undercover government agent who's quick with her wits and fists, knows punishing cold and dwindling supplies are to be feared. But in the ruins of an ancient Nordic outpost, a centuries-old message warns of a threat far worse: the Draugar—the dreaded "again walkers" of Viking lore, the terrifying living dead that spawned the legends of vampires and zombies. Now, roused from their cursed slumber, these gruesome Viking warriors and their monstrous queen are hungry for living flesh—and eager to spread a ghoulish contagion from their long-buried prison across the globe.
