"Dumbledore's Army and the Year of Darkness" by thanfiction

http://www.fanfiction.net/s/4315906/1/Dumbledores_Army_and_the_Year_of_Darkness

I'm not really familiar with thanfiction's fandom history  but this is a pretty well-done fic with a fairly ardent fanbase. I usually try not to rec stuff that's already well-known unless I truly love it (like "My Immortal" or "Slytherin Spy") but I really quite enjoyed this and I figured, Why the hell not?

It's about what happened for the DA during year seven. Pretty enjoyable.

"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.

"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.

"'The Parallel Worlds' Series" by LouisaB

When I started this blog, I decided to only recommend one fic per author, and that was it. After just a couple of months, I'm already bending the rules, though in my defense, it's for an interconnected series.

I left out one story there - "Catch a Quaffle," technically second in the series, though it has nothing to do with inter-dimensional Marauders as it does Remus/Sirius fluff. And I just don't care about that.

After accidentally opening a portal and finding a parallel universe, the marauders (and Lily!) get into all sorts of adventures and wacky hi-jinks. These fics are actually really well-written, enjoyable, and pretty damn brilliant. The different marauders running around at all times is sure to make you smile. I doubt these fics would be half as popular as they are if it weren't for the RLSB aspect, but I actually feel like that's the weakest part to the whole series.

"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.
