The Raven (Jane Harper #2)

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.

Now Jane’s Nordic allies and a motley crew of mates are shoving off on a new monster-killing ship to take the battle to the insidious creatures before they take over the world. This time, though, they’re up against more than just a handful of ancient zombies on an isolated island. Even if Jane and her crew can conquer an army of the swimming dead—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.
