Definitely an interesting story and I'll second Clell65619's comments. I, for one, do appreciate the spaces between paragraphs as it improves, IMHO, the readability of the posted story.
It should be interesting to see if Hermione warms up to Harry after her initial annoyance as, even in a different house, she could/should be a great friend. And without Harry there to restrain Ron, I fear for how well she'll do as a Gryf.
