Jane Harper started out as an undercover whistleblower among a group of radical activists butting bulkheads with whaling ships in the Arctic Ocean. She ended up shipwrecked off the coast of Greenland and teamed with a pair of father-and-son whalers to destroy their own six-hundred-year-old Viking ancestors — resurrected as zombies by an insidious race of intelligent parasites. Quite a lot for even a tough-talking, two-fisted, former military brat like Jane to handle.But winning their battle against the undead Vikings was just the beginning of the war against the parasitic Draugr now that the relentless creatures have escaped their island prison…and seek to turn the earth into a planet of the living dead. With a sturdy vessel under her feet, a do-or-die crew at her side, and weapons of mass monster-destruction in both hands, Jane takes to the hellish high seas to face down zombie whales and an armada of seafaring ghouls.
