I've never read anything quite like this. I don't know that I would have searched out anything quite like this. But, oh goodness me, I am glad to have stumbled across it.
From writing style to concept to character, and above all with the delicate balance of the dub-con, this piece is exquisite. I think I can fairly call it my favorite of the winter HP fics that I've read this year, and that's not something I would have expected. It's amazing that, for such a concept, it remains so plausible to the characters and within canon. It treads a delicate balance, maintaining the danger and threat of Gellert while still giving Albus every reason to return to him again. That takes skill.
Wonderful work, anonymous author, and what a lucky recipient. This is brilliant.
