The Sentinel — Jeremy Bishop

Something sinister lives in the frozen north. Something old. Something evil. Stranded in the aftermath on a desolate island off the coast of Greenland, the survivors of a shipwreck 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 that 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.
