Author has written 29 stories for Harry Potter, and Downton Abbey.
I used to write Harry Potter fanfiction (and occasionally still do, as fanfic retirement seems somewhat flexible), the majority of which features Remus Lupin and Nymphadora Tonks. There are also some Marauder-era tales and the odd venture into AU. Other stories, such as R/T drabbles not published here, can be found at my fanfic journal, gilpins_tales, over on LJ.
If you're an R/T fan as well, you may enjoy rt_morelove, a LJ community, which has an event about to start on December 12th, 2015, running over the holiday period into next year, with the most recent fic and art as far as I'm aware. And there is always metamorfic_moon, a LJ community which is no longer active, but with over 500 fanworks, both fic and art, archived there.
