You had me worried here...briefly. Thank goodness Fleur happened along or Harry'd be a slave for sure. I'm glad to know that Zoe, Marisa, and Laret aren't bad, just thoughtless. I wondered if there was going to be fire-fight, but was glad to see that Fleur was able to bring those other three to their senses.
I have to agree with Arkenstone007 on the reason Harry's not usually open to Veela allure. It IS his ability to throw off the Imperius curse as the Thrall works much the same way. He probably would be immune to the Vampires' Thrall as well.
I notice you stick with Harry's innate nobility and honesty in your fic. Good. He may have to do some underhanded things, but he never does it to directly hurt anyone and it's usually associated with his or a friend's safety. That Harry took the unbidden Wizard's Oath to prove the veracity of his story speaks volumes. If he'd only done that when his name came out of the Goblet for all the school to see, he might have been spared a lot of grief and Ron's jealous nonsense. But teenagers must be teenagers, and they'd find another reason to harass Harry, I suppose.
Anyway, you've kept me interested and yes, you have some spelling and usage problems, but nothing we, as readers, can't get past. And shrink that room in Chapter 1. LOL
GOOD JOB!
