I don't usually read either of these pairings (I tend to read and write Harry/Ron and Remus/Sirius), but I was very impressed with so much in this fic. There was plot. There was incredibly beautiful writing. And the length of it. I know, size isn't everything, but this is a novel length fic for a GIFT.
I hope your recipient appreciates this fully. I know I would, because the amount of work that's been put into this is incredible.
