If you read Harry Potter fanfiction, you need to go read The Rain in Spain by Ishafel. It's a genfic about Frank Longbottom. The summary is A brief look at the aftereffects of Cruciatus. If you read the Niffled fic at Fiction Alley, you've probably read it already, but I thought I'd recommend it to those who don't usually check out the forums. It's short, but it's so good.
