Teaching The Boy Who Lived : A Multiple-fandom fanfic

When Percy Jackson, Katniss Everdeen and Doctor Who go to teach at Hogwarts, Harry is suspicous. Why does Percy have a Death Eater tattoo? Who is the new Doctor? Why is there a girl who constantly carries around a bow and arrow and jumps at every threatening noise? Why is there another doctor who has shaky hands teaching different magic?

Meanwhile, Percy is having difficulty teaching. He does not know magic. All he knows is fighting.
Katniss is having a hard time teaching at a school for wizards. She never knew that kids were being forced to fight in wars like she was forced to fight in games. She keeps having terrible flashbacks to the Games as well.

I don't really know much about Doctor Who. Apologies to all those whom I may offend!

I got this idea from GeekGalaxyGirl, she is a very good author, definetly reccomend reading her works.
