"The Strange Disappearance of SallyAnne Perks" by Paimpoint

http://www.fanfiction.net/s/6243892

I love when stories uses flaws in Jo's writing to create a whole story arc. The only complaint I have about this story is that the author TOLD us the timeline in author's notes instead of leaving it up to the reader with clues in the texts, but really, this is something y'all should check out.

Do you know what happened to Sally-Anne Perks? To quote:

There weren't many people left now. "Moon" "Nott" "Parkinson" then a pair of twin girls, "Patil" and "Patil" then "Perks, Sally-Anne" and then, at last - "Potter, Harry!" (Harry Potter and the Sorcerer's Stone, Chapter 7)

Ten minutes later, Professor Flitwick called, "Parkinson, Pansy - Patil, Padma - Patil, Parvati - Potter, Harry." (Harry Potter and the Order of the Phoenix, Chapter 31)

~At some point between September 1991 and the spring of 1996, Sally-Anne Perks left Hogwarts. Perhaps she dropped out of school. Perhaps she fell ill. Perhaps she died. Or maybe she just vanished...

"Moving On" by LadyKatie

Fuck, I love this fanfic. It's Harry/Draco, post DH. It's canon compliant (minus the epilogue, natch), and just ... fuck.

It wasn't perfect. There were a couple of scenes where I rolled my eyes (and some cringeworthy sex), but nothing that made me stop reading. I also love how this fic explored the notion of Wizarding Britain after Voldemort's fall.

I mentioned in my last post that I was never a Harry/Draco fan, but if one fic were to make me like the pairing, this is it. This is my "Dating Disasters of Sirius Black" for all the Drarry shippers out there. This makes sense to me.

"Harry's Brom" by Hans van Hozel

Hans is one of the most interesting writers I've read in a long time. The way he plays around with the constructs of the English language is amazing. The way he continually references the moon, using it as this analogy for the emptiness of existence is amazing. Hans dares ask, "What does Harry's broom feel?"

The romance between Harry's Broom, Brom, and Harry's owl, Hedwig, is beautiful and realistic. They both can fly, but neither one has a concrete identity. They both "belong" to someone else - Harry. Can you belong to someone else, and still be your own owl or broom? It's a worthy question to ask. I could do a Marxist reading of this, and perhaps someday I will.

"The DADA Professor" by RJLupinFan

I don't really know what to say about this fic.

It's about a seventh year student who gets a crush on Lupin while he's teaching at Hogwarts. It's bit hackneyed in some respects, and the writing's rough, but it's charming. It's not about a Mary Sue gushing about a Professor, it's as canon as one of these fics can be, minus one eye-rolling, backbended way of getting Lupin and the student to kiss.

I don't know. There's something to this fic. It's worth reading.

"My Immortal" by XXXbloodyrists666XXX

I don't really need to talk about this story, I just wanted to post it because I genuinely love it. If I had to name my favorite fanfic, this would probably be it.

"Harry Potter and the Slytherin Spy" by Christine Morgan

What if there was another Hogwarts student in Little Whinging?

This fic, written/set right after Order of the Phoenix, is about Harry meeting a Slytherin girl and forming a friendship with her in his sixth year. It's fairly-straightforward and not excessively (wonderfully) violent at all. (Sarcasm.)

Morgan can imitate Rowling's writing style well, and there is something so satisfying about reading a fic you can confuse for the genuine article; especially when it gets to where Morgan is describing gruesome deaths in Rowling's simple, yet descriptive prose.

I'm not pretending this fic is without problems; it's focused on a female OC, which is a no-no to most in the fandom, though trust me when I say the writing is good enough you won't care. And there are a few canon things that would raise eyebrows - Kreacher's characterisation is all wrong in this fic, in my opinion, while I think Morgan's explanation of where Sirius was hiding during Harry's thirteenth summer is a brilliant twist. Morgan also abuses ellipses, and the ending seems a bit rushed and simplistic, but trust me when I say:
YOU SHOULD READ THIS.
