Very nice -- not fluffy, but just enough hope. They're all wonderfully characterized, even Caelum with his longest-sentence-ever. I like Seamus's sense of humor, his honesty, the whole cash/cache gag. This section in particular sums up just what I like about the characters and tone:

Pansy rolled her eyes. “Cache, Finnigan, Cache. You’d think someone had tied your tongue. Just make sure you say it right. I don’t want my son ending up in a vault at Gringotts.”

Seamus grinned. “Sure thing. Hey, I bet this’ll piss Malfoy off, eh?”

Pansy raised an eyebrow. “Think you can handle it?”

“Do banshees scream?”
