The idea of Hermione coming charging to Harry's rescue is a nice one indeed.
I enjoy your stories, but I think all of them - that I've read so far - are much the same in that there's little 'friction', little possibility of things going wrong, H/Hr and everything else is a fait accompli, everything is plain sailing. Well, maybe that's unfair; I've just finished reviewing two of your shorter stories that *don't* have Harry and Hermione together, after all. But everyone (except Ginny) is still so *happy*!! It only takes Hermione about three milliseconds to cast Ron aside in this tale, he's left behind without a thought in the sonic boom as she rushes to Harry's side, no doubts whatsoever.
She'd been with Ron a long time, they'd lived together? Made love, et cetera ... I would have expected some inner turmoil, some measure of regret, some acrimony, before both Ron and Hermione acknowledged the truth/obvious and let bygones be bygones. Or maybe you could have shown us a bit more of the R/Hr problems that had been leading up to the start of this story?
You know, I had to put this down half-read for a day or two, and one thought kept popping up in my mind - how GOOD a friend Luna Lovegood was to Harry and Hermione. I was pretty sure you were going to have her end up with Ron (like you, I quite agree that canon!Luna showed definite signs of interest/crush in Ron, and he started appreciating her more, too, in the last two books) and I suddenly realised ... how wonderful was Luna, to put her own feelings aside and calmly wait for Ron and Hermione to break up? Rather than crash in, try and split them up, or otherwise interfere?
Maybe I'm being too magnanimous ... maybe your Luna, in your eyes, had enough seer to 'know' that she'd get Ron if she just waited (goodness knows you seem to give Luna all sorts of abilities :-)). Or maybe Luna just realised that her relationship with Ron would be strengthened if he was allowed to work out for himself that Hermione wasn't the girl for him, in his own time.
But I was still struck with the idea of good-friend!Luna, sitting by and giving her friends all the time and support they needed, placing her own needs for love on the side. I desperately wanted a scene to come up in the second half of this story where Hermione would, suddenly, be hit with this sort of epiphany - isn't it nice that Luna and Ron are together, it's what she always wanted, she -- wait, does that mean that, all those times when we were with Luna, she was, all along, desiring Ron ... but staying well clear of him, just because of our friendship? Oh my gosh, what a good friend she is, I don't deserve her a friend like her ... and then a big Granger-class hug for Luna would follow.
I know it's sappy, but I like stories that make me think of things like that; I otherwise have zero imagination, so it's nice when I can 'get into' the flow of a tale.
Anyway, I do note that you did insert the beginnings of R/Luna near the end of the story, even if you didn't have Hermione suffer a breakdown over the realisation of what her friend put up with for her sake. :-)
The image of Harry's parents warding off Ginny was cute, if a bit 'over the top' for this romantically deprived male reader. I didn't much like the caveat that they couldn't appear to the principles themselves, which made the whole artifice a bit too 'artificial' for me.
"Broken Arrow!", hey? I had thought it might be 'Hey, Rube!'. :-)
Thanks for the story!
