Er... why is the story called Zombie? What the hey - this was very well written; I would be happy to see it continued for a few chapters. It's an interesting stage in Snape's life, and canon has told us nothing about it yet.
Author's Response: Zombie was a song from the Cranberries that inspired me. I was going to have the lyrics intertwined in the song, buy it never turned out right for such a short fic.
It has a lot of hints for the plot in the song.
Well done! I like the dialog and I love how Snape stays in the shadows.
