The Haunting of Draco Malfoy

After the War, there are many new ghosts, lost and uncertain. Draco Malfoy is a Peacebringer, working hard to help these and any other troubled ghosts move on. He finds himself in a Gothic mystery of his own when a recently missing Potter appears, spectral and silent, at Malfoy Manor. Warning: suggestions of possible main character death, but overall I'd say this is gentle angst.
