Oh, this is fantastic. The perfect combination of hilarious, plotty, and hot, with an ending that manages to be sweet without being saccharine.
Draco really does have the appropriate sense of dramatics for this line of work, I must say. And it would take some humbling circumstances to turn him into a better sort of person. His POV here is great; he's lost a lot of his egotism, but he's still proud and sarcastic, and has gained a bit of perseverance out of necessity.
The wand from Wicca Weekly made me giggle madly, as did the Luna cameos. Luna's great -- older, a bit more together, but still very much Luna at the core. I really liked Marguerite, also; you put an extraordinary amount of presence into a character who's only on screen for a very short amount of time.
Dirty-talking Draco; gnnnuh. And the rushed sex scene, with the customer just on the other side of the tent wall -- abjkefuh! I was absolutely on the edge of my seat with the tension through that scene. Awesome.
