KEYWORDS: Nagini, Wormtail, Snape, Malfoy, Sirius

Sands of Time (chapters)
By Ariana Deralte
KEYWORDS: Dumbledore, Salazar Slytherin, Godric Gryffindor, Severus Snape, Harry Potter, Conspiracy, Immortality
SUMMARY: Harry has always trusted Dumbledore, but does Dumbledore truly deserve that trust? Strange things are happening at Hogwarts (well, stranger than normal…) and Harry has no one to turn to with his suspicions except Snape?!

The most elaborate spin on the "Dumbledore is Evil" theories yet! Really good.

The Unknown Witness (novel, abandoned)
By Athena_Arena
KEYWORDS: Harry Ron Hermione Sirius Summer Lupin Arabella
SUMMARY: What if, when Sirius Black was framed for murder, there was a witness who'd seen the truth? A Muggle who held the key to Sirius' freedom? Well now it's time for her to speak out. The Unknown Witness is a wanted woman, and it's not just Harry and co. who are trying to track her down...

The last thing she heard before passing out, as her brain began to scream out in the agony the loss of one of her vital senses caused, was a laugh. Not a laugh filled with happiness at a job well done, not at the satisfaction of the destruction caused, but the laugh of the dark haired man. She could imagine it, as if that image had been burned on her memory forever, etched into her skin as a reminder of how he'd been betrayed. It was the laughter of a man driven to the edge. A man who knew, in that instant, that he'd lost everything. A laugh at the cruel fate the world had awarded him. And as she felt the movement of a deserting rat across her feet, she would have sworn that underneath it all, there was the inner howling of the blackened, stray dog.

Balance (chapters)
By Rabbit
KEYWORDS: Harry, Draco, Snape, McGonagall, Hogwarts Founders, Student Body, Dumbledore, Forest, Castle
SUMMARY: Hogwarts is under siege, and it's going to take everyone to find a way out of danger.
Guest appearances by everyone, including dead people and people who should-be-grown-up-but-are-not-thanks-to-the-time-warp. Really cool. Very visual and the atmosphere is expertly incorporated. Lord of the Rings reference.
It's a nice break from all the Action/Adventure fics with Voldemort as the only danger.

Dimelo (novel)
By Malena
KEYWORDS: Azkaban, Dementor-Depressed!Harry, Weasleys, Lupin, Sirius
During the summer after the Triwizard Tournament things take a turn for the worst. Cedric is dead, but most are unsure of who killed him. Now it's up to Harry's friends to get him out of a sticky situation, but will Harry ever be the same?

Draco Dormiens (chapter story)

The first part in the Draco Trilogy you've heard so much about from the Draco fans.

Sirius is kidnapped by Voldemort. Hermione drags Draco [in the guise of Harry] on a rescue mission. Ron and the Twins show up, too. D/Hr, H/Hr

The REAL Chamber of Secrets! (a few chapters)
By Ges

They made it to Snape's dungeon, and gloomily walked in. Snape was sitting there, smirking his head off. Literely.

"Opps." Snape picked up his head, and screwed in back into his neck. "That happens sometimes. Anyways, as punishment for being alive, you must clean OUT MY CLOSET! And it hasn't been cleaned out for the last... Fifty Years."

Gryffindors and Slytherins (long chapters, but not a moment of boredom)
By Ayla Pascal
"What happens when most of the Slytherins decide to leave Hogwarts? When the Dursleys decide to move to the USA, it’s only the beginning of a very exciting year for Harry Potter. Mysteries, house switching and Mentally Disturbed!Snape galore!"

This is a brilliant fic by an author who obviously did her homework. There are some things you might scoff at (house switchings, for example), at first, but you'll soon see why I added this fic to my list of favorites.
