So, you're not into puppy shipping. Or maybe you don't usually read marauder's era fics. I DON'T CARE!! Some of the best writing I've ever read in fanfics is being posted there.
The stories feel so real, and the characterizations are so spot-on. Most of the fics are of a managable size, and so much is written in this lush, believable, thoroughly readable style that it's just blowing me away day after day.
And even if you can't commit to reading, you have to see the art.
Anyway, go there, read, comment, give them some love. It's on livejournal and insanejournal.
