Demons, mates and Vodka by DinosaurDread reviews
Kind of a self explanatory title. Harry x Sebastian. Demon!Harry. I can say that there are a lot of cats, demons, mates, and vodka shows up occasionally. No out-right bashing of any specific character that wasn't a canon evil, so if you're reading this to fuel your desire to see certain people be put in a corner of shame and embarrassment... . Rated T to to be safe.

Black Knight by dreaming of rocketships reviews
It seems like everyone is after the Boy Who Lived. With a Dark Lord on the rise, a Ministry doing its best to slander his name, and a Headmaster who won't tell him a thing...well, Harry Potter's pretty stressed out. Cue dramatic music, a mysterious crow, and a possible concussion and whole lot is bound to change. Maybe for the better but that's subjective at best. HP/SM.
