The Raven

A battle to the death with six-hundred-year-old zombie Vikings in the frozen far North was just the beginning.... Undercover activist Jane Harper and father-and-son whalers Jakob and Willem Olavson thought they sent the walking corpses to their graves for good, but the intelligent parasites controlling the dead flesh lived on to keep fighting, and infecting. This time, though, even if Jane and her crew can conquer an army of murderous and cunning zombie whales, they'll still face a floating graveyard of ghost ships packed stem to stern with the next wave of the ravenous undead... who are hungry to settle the score with the last hope of humankind.
