What a brilliant read! You made the characters and pairings really come alive, and I love the many references to intercultural themes, from the obvious wizard/goblin to British/French and Griphook's acceptance of making allowances for Fleur's different background (however right or wrong Auntie Muriel may have got it there.) And your portrayal of Muriel with her cherry-wood cane is a triumph.
Apart from how you wove those great pairings into a smoothly-flowing, so well-written story, I loved lines such as: --Muggles, unable to communicate through fireplaces or by sending patronuses to each other, had to leave their marks on walls, like wild kneazles. -- Ginny demands to know why you won’t let her visit you. She’s furious. She says don’t be stupid and Percy-like. -- Rita Skeeter’s piece Mysterious, Moody, Misunderstood – the Many Faces of a Reformed Death Eater had been mildly interesting; she had never known that that sour-faced skinny Yorkshireman had, in his youth, been caught in a love triangle with Lily and James Potter. -- eclecticity and tephelone. Sounds like Arthur is making rapid progress /g/.
