I've read this years ago and remember how much I loved it, even if most of the finer plotlines had escaped my memory. It seemed like the right time for a re-read and I'm very happy I did!
The story is well thought out and very elaborate. I love the first two chapters, even though I know it's quite a stretch the guys wouldn't recognise her at all, especially after talking and having lunch with her and still not catching on. But the idea of it and the banter in those chapters is great and I laugh every time I read it. Most of the OC created by MissFantastic are really horrible people, they're dumb, stuck-up and vindictive, but they are well written and the situations they're a part of are mostly funny.
I can't help myself, I love a story where Hermione is this Goddess (literally in this one) who has it all: beauty, intelligence, friends and (an) amazing wizard(s). Which then mostly means there is a storyline about someone being jealous of that and trying (and failing) to ruin it for her.
I loved the lore and background involving Sorcery that was created for this story, it was very detailed.
