Loved it! The carnival atmosphere is so great, and the mixed fun and bitterness of Draco ending up there without magic and harrassed by the wizarding 'authorities' worked extremely well.
The H/D was wonderful, hot and with real emotional depth (even though Draco tries not to let it show). And plot! Really good plot too :).
The ending, tentative and uncertain as it was, made me very, very happy. To see them trying fits the story much better than a perfect happy resolution would have.
And I've had 'Puff, the Magic Dragon' running through my head all day now... ;)
