I agree with "Cateagle" on all points.
I'd like to add that I don't think ring is good source of power, JUST BECAUSE if he looses the ring then he's powerless. I wonder if you should mention that only Harry can take the ring of. It can't be taken off or can't loose by accident or something.
And yes, I do hope its H/Hr and you plan on doing something about his "problem" soon.

- The fact that the ring cannot be removed by another will be shown in a chapter or two... This chapter I concentrated on showing that it only works for him.
- He's only 14, she's almost 15. It's a little early to be taking care of that 'problem' without it being kiddie porn, which I will not do.
- Though Harry is going to have to deal with his 'Special Purpose'...
and probably Hermione with hers...
