Lord of the Zombies

Middle-Earth is ravaged by a continent-wide storm, which leaves the living dead in its wake. Thranduil's halls become destination number one for all who survive, whether the Elves like it or not. But Galadriel and Elrond know that it will be far from over even when they reach safety: whatever caused the storm, and the rise of the dead, was strong enough to topple Sauron himself.
