Quick Rose/Scorpius fic rec:
All Our Tomorrows by
sandrine Most of the Rose/Scorpius stuff I've seen has been slightly pants, clearly written by 14 year olds rehashing Draco/Ginny (or Draco/Hermione), but this was really, really good. And there's House stuff. I love it when people discuss the Houses, because I think it's the one giant flaw of Hogwarts, and I don't think JKR did enough to show that it shouldn't matter.
