Challenge: A story all from Snape's point of view. Must include Snape finding out about neglect/abuse subtlely. He must doubt what he is seeing due to cognitive dissonance. He resists acknowledging the small signs because he would then have to change his behavior and it's hard to change ingrained behaviors. Then something happens that he can't continue to ignore and it causes him to have a profound paradigm shift, rocking his world such that maybe even something in his magic is changed. (JKR established that thought and emotions are important to magic - i.e. Patronus changing forms.) This may cause his behavior to change, possibly at first without him realizing it.
I'm looking for a good character study with Snape as the voice of the story. I'd like to see what his life is like outside of classes, he's a person with a life outside of work, show that.
Nice to see but not required - a friendship-type relationship with McGonagall, could be ongoing or developed over the course of the story. Possibly starting with mutual respect but growing into actual friendship as Snape changes.
Must have some kind of relationship develop between Harry and Snape, but I want to see it all from Snape's perspective. Any level you'd like, but they no longer hate each other.
May NOT have Draco as a main character/be used in any way to move the story forward. This is a Snape and Harry story, not a Snape and Harry and Draco story.
Romance for either character is fine, but shouldn't be a major point in the story.
