Two stories that cross Discworld, Doctor who, Harry Potter, & House.
Fandoms: Discworld, Harry Potter
Title: A Sudden Witch
Author: Raven Aorla
Summary: Tiffany Aching is minding her own business when a teenage witch appears in her dairy shed. Usually this sort of thing only happens to wizards, but this 'Hermione' needs some counseling and a lesson in what witchcraft really is about. Post Wintersmith.
Who wouldn't want to see Tiffany and Hermione team up? May contain spoilers for Half-Blood Prince and beyond but I'm not sure since I bailed on reading HP canon within the first few chapters of HBP and the things mentioned may not be canon.
Fandoms: Doctor Who, House
Title: As the Crow Flies
Summary: Ten falls out of the sky and ends up at Princeton Plainsborough and then e and House ggo on a wondrous journey of self-discovery in a giant motor home named Princess Love Machine. To Canada. Where they eat eggs and bacon on a magic hill. Tragically.
I've never gotten to see an episode of House and I still loved this one. Empatheia has mixed whimsy and sorrow and two of the loneliest men in the universe into a really touching story.
