Hi Laura! Finally getting around to answering these. Really, I'm glad that you came by to ask me questions at all.
1. The Jily AUs are written in a specific order. There was a Jily Valentine's Week on Tumblr, and each day leading up to Valentine's Day was a different AU--so that's why coffeshop, bookstore, etc. was written in that order. The last one, my 1920s AU, was a "write whatever kind of AU you want" day. To be honest, I'm basically finished with all of them, but I would love to expand some of them eventually.
2. Haha, stalk away! Playing for Keeps is troublesome because at the time I wrote that, I had about 20 chapters, but now I've got around 34 with basic (read: extremely basic) outlines. And each chapter keeps getting longer, so I keep turning one chapter into two... It's getting out of hand, to be honest! Right now, I'm working on Chapter Nineteen, which was originally Chapter Seventeen...
3. Lolol, me? Good at planning? Certainly not. I outlined those chapters for NaNo so that I would have some kind of idea, but there's really no telling if I'll actually follow it. I keep switching the events around to even things out, and I feel like there's way too much interaction between James and Annie and not enough detail about whatever's going on with Freddy & the gang (spoilers!). I really didn't think the whole Freddy thing through (you'll have to find out when you read the newer chapters--I don't want to ruin too much for you!), so I'm having to make up stuff left and right to reconcile it in my head. It's a massive trainwreck. Tldr: I'm actually terrible at planning and you should find someone else for advice. But thank you!
4. I would probably never write about Hogwarts era. Trying to write in "missing moments" or changing around canon just doesn't appeal to me that much, although I've read a lot of stories that did that and were good. I just couldn't do it. I would not want to write the Golden Trio for sure, because that's just too difficult for me to fathom. Although who knows? They might have a cameo in PfK if things work out...
5. I'm wrestling with PfK right now, but I would love to continue my Jily Road Trip AU chapter, perhaps turning it into a short story or novella. Other than that, I have this insane longing to write a Dudley Dursley/Marietta Edgecombe office romance, based on a Tumblr headcanon about them falling in love because they know how it feels to be on the receiving end of hexes and such. I don't know if I'm up for writing a romance, though--it just isn't what I do, you know? I also have dreams of continuing one of my one-shots, The Willow Tree, which is about Hugo Weasley. And I'm determined to write about the Hogwarts Orchestra, which is something that would allow me to wax lyrical about classical music. But I haven't actually written any of this down, so it's still up in the air.
6. ALL OF THEM. I love tea, especially this pomegranate green tea that I have, and coffee is really good as long as it has lots of cream and sugar in it. Hot chocolate is delicious because I love chocolate. So yeah, all of the above.
7. It always makes me so happy to know that you love PfK. When I made Freddy up, I wanted him to be a con man with a scheming mind. I expected him to be slightly sexist and underhanded, and fairly gross, too. But I didn't expect him to be into musicals/theatre, and I certainly didn't expect him to be into dressing in drag. He's a pretty zany character, but he's so fun to write.
8. My NaNo plans on 30 March were pretty much "Write PfK. Write business proposal. Write essay. Write reviews." And that's pretty much what I've done, surprisingly enough! If I could only get this essay finished (I have two pages right now and I need four more before Thursday), I would have the rest of the month to focus on PfK. But alas, procrastination is a real enemy!
Thank you so much for the lovely questions, Laura!
