This? Is amazing. The amount of research and love you put into this is so clear. The details, the narrative voice, the dialogue, and even the characterizations all felt just right for the period. And the gentle development of the relationship between Severus and Harry was lovely.
“Do you have a family, sir?”
Albus chuckled warmly. “Of sorts. One is in his study, doing something terribly serious, I assume, and the other is turning the pie crust to leather as we speak."
If I had not looked again at that very moment I would have missed the boy's awkward swallow as well as the overwhelming gratitude that shone out from his damp eyes. I had forgotten how striking hope looked on the face of a child.
I adored your Albus, and found this passage very moving. ♥
Incidentally, this bridge was my favorite site in London. :-D
