Lost Undead

Zombies never stay dead.
They made it to the island. They managed to find a way to escape the burning cruise ship where they'd been trapped, and now they're facing a new problem.
The zombies didn't go down with the ship.
They're here.
They're everywhere.
Winter and her friends need to find a new way to escape, a new way to keep fighting.
If only the dead would stay that way.
