Okay, so I generally am not into AU, especially not AU where Draco isn't even a wizard, but this was great (even though I'm not familiar with The Dresden Files). The world you constructed feels natural and not as removed from the canon world as many AU fics are; I'm actually finding myself wanting to know more about Gabriel and his merry band of werewolves and how they fare in their struggle for equal rights, as much as I don't agree with their methods... OTOH, I'm kind of glad you left that open, because it served to bolster the world as one with ongoing problems that might not always be in the forefront or on the characters' minds, which makes it feel more real.
Ornery ghost!Snape was fucking brilliant. And from this day forward I shall maintain that accidental bottom!Harry is the best kind of bottom!Harry. XDD
