Harry Potter • 2898 stories • Updated 18 Apr

Hot chicks with pointy sticks meet young wizards with, er, pointy sticks. Lots of pointy stickiness all-round as Harry, Ron & Hermione get a little help in the war against Lord Voldermort. And what will the Ministry of Magic make of wandless witches and DADA teachers that take a more direct approach to the defense aspects of the job?

On the other hand, see what happens when the Hogwarts student body gets exposed to not quite so muggle life in Sunnydale. All this and more to be found in our massive collection of Harry Potter crossover stories.
