I do most of my reading on my kindle, so that definitely helps, but I have a massive collection of html files from before there was an AO3. There were just too many times when I was a wee fangirl that someone flounced or locked or couldn't pay for server space and now archiving is a kneejerk reaction.

Do you remember the title/author? Because I love both those things and I finally have things organized enough that if I have it, I could actually find it.
