Here's the link to the fic on Teaspoon
I had this fic planned for the week after next, but as long as everyone who wants to read it gets a chance to, that's all that matters. I've heard a lot of people praising this one, though it's made at least one person cry so I don't know whether it's a very sad one or not. Nonetheless, as a precaution, I've downloaded it - just to be safe. I really hate it when good writers take their fic away from us! =(
Happy (?) reading, everybody!
