One to the Other (Harry Potter/Avatar Xover)

Jake knows he should be over Tommy's death, but ever since he became Na'vi he can't seem to shake the loss. If that isn't enough to deal with, he is trying to make sure 'the Sky People' don't just turn up and blast the crap out of Pandora from orbit. When a sealed lab is found at Hell's Gate containing two very strange Avatars things just become even more complicated.
