Summary
He shattered. Lost himself in so many bits and pieces that when one blow - wrong place, wrong time, wrong person - hit just right there was nothing left but to break. To drop. To shatter.
No amount of molten gold, duct tape, or superglue could put Shane Hollander's pieces back together again.
Not on his own.
Fortunately for Shane, at the same moment he was collapsing under the weight of it all, an infamous sports attorney/manager/problem solver was there to sweep him up off his skates and help him back to himself.
Stiles Stilinski had never met a problem he couldn't solve - one way or another. Including with a baseball bat or molotov cocktail if necessary. If whoever had used one of the sweetest men he'd ever met and left him to Drop ever came back around they just might find that out the hard way.
As for Ilya Rozanov, ignorance may be bliss - but it also has consequences.

Summary
Lady Enora Dominique Rosier had been born for one purpose and one purpose only: to secure the heritage of the Noble House of Rosier. Born into privilege and power, in a society that required nothing less than duty and sacrifice to keep it. Two paths to glory laid before her: first, a marriage to the House of Black. Or second, nothing short of entering the Harem of the Emperor himself, the only other choice that would prevent her godfather from being offended on his grandson and House's behalf if she refused him.
Protocol said that it was the Emperor's Choice that mattered.
Rose begged to differ.
An Imperial Harem A/U, bridging the Riddle and Marauder Eras, focusing on Harem Politics and a dash of romance and smut.
Let the games begin.

Summary
The Fourth Shinobi War wasn't going well. Shinobi were dying right-left-and-center. Ono Toshiko had done what she could to avoid it - and failed.
Her little brother had a plan. A fail-safe. A seal attached to her heart, mind, and chakra network so that if his latest knuckle-headed scheme to fix their world failed, there would still be hope.
She agreed but prayed nonetheless that a miracle would occur and after the war was over Naruto would take the seal off of her.
She should have known better.
After all - if there were deities listening, they clearly had no mercy for a reincarnated soul. Especially not enough to *not* force her to do it all over again. Only in a new body, and a new time.
An A/U of Reincarnation for the Win.

Summary
The first visitors the Earth ever knew were the Alterans, an advanced alien race who seeded two galaxies with life in their own image - even as they fled from their mistakes, leaving their abandoned children and aborted experiments to struggle without them.
First among their descendants were the Tau'ri - humans of Earth who had spawned a secondary evolution when their creators weren't watching: Sentinels and Guides, stretching back as far as humanity could remember or their artifacts recalled, their protectors and defenders facing every threat from without *or* within.
All that came after: Ori, Replicators, Goa'uld, Wraith; slavers, Nazi, colonizers, NID, the Trust; all came to find that the first obstacle was never the last, not so long as the Sentinels, Guides, and their Council still lived.
So it made sense that the greatest defender Earth had when they realized that humanity wasn't alone in their universe was a Sentinel.
Just as it was fitting that the greatest protector all of humanity had would be a Guide, whose fierce loyalty was almost as legendary as his ruthlessness.
And then there was Atlantis: the Lost City, abandoned and waiting for her people to return.

Summary
Baelor is thirty six, the crown prince, and has buried one wife already. He did not ask for another but a rebellion does not care what you ask for, and so he found himself wed to a brother half his age in the name of Targaryen unity.
Maekar is eighteen, an omega, and has spent three years at Summerhall understanding exactly what he is to his husband; an arrangement. A political necessity. An afterthought, not that this is anything new.
With the rebellion reshaping itself and a unified front to maintain, they are summoned to King's Landing to begin the marriage in earnest.
Neither of them is particularly pleased about it.

Summary
What if Aerion, though insane, has a point?
In which, Aerion is more like Daemon Targaryen and refuses to bow down to Andal traditions, and well, that’s it.
That’s the plot.
House Targaryen with actual balls to back up their insanity.

Summary
In Westeros, Baelor Targaryen and Jena Dondarrion had a daughter between the births of their two sons, their Alysanne. Then by dark magic, she was snatched from her cradle right in front of their eyes with no answers or leads to follow.
On another world entirely, in Great Britain, a prophecy foretelling the one to defeat the Dark Lord was uttered, but no one knew who it could mean. Yet Voldemort was never one to merely accept any fate prescribed of him. Through a powerful ritual, he summoned the child to him intending to kill this girl before she could be his doom, but the girl was saved, adopted by the very Potters who had helped save her, and years later defeated him exactly as foretold she could.
Allie Potter was a young woman who never knew where she had come from or where she would belong. By a strange twist of fate, the answers would land directly in her home when she least expected them to. Such was her life.

Summary
“Let me help, love.” The new pet name was only used when they were alone like this. Somehow the word was both too weak to describe what their coupling actually meant and a far more intimate endearment than what Derek felt that he deserved. What they were doing wasn’t love so much as need. He could sense his wolf curling protectively around what belonged to him, what anchored him, and what strengthened him as the Alpha. True, his pack was small: just him and Peter. But that was enough – for now.
A spicy reimagining of Season 2. Old foes and a new threat emerge, all while the Hale wolves begin to fall for a very human high schooler with deep brown eyes and a loud mouth. Expect a lot of familiar plot points from the canon, just with a twist. Mostly an excuse to write uncle/nephew werewolf smut.
