Read the story.
Heart pounding, Feng dashed down the hallway to her apartment while a gang of ghouls and ghosts thumped up the flight of stairs behind her. With trembling hands, Feng tried to open her apartment door, but the old key resisted her desperate attempts. She rattled it, but it wouldn't turn.
