I have a confession to make. That confession being, that I absolutely loved this story, despite my general dislike of the sex magic deus ex machina, on which, in this case, Snape's reaction sold me.
The wonderfully spot on characterization; the believable maturity that both of them developed after the war, particularly Snape's inimitable voice, the detailed plot, Hermione's (and obviously your) passion for books and knowledge brought to live with gorgeously detailed descriptions.
This is fast becoming one of my favorite stories. Awesome work! <3
