Stargate: Atlantis
Love Is a Long Long Road, by Hily and Telesilla. Slash, John Sheppard/Rodney McKay. (ca. 40,000 words)
If you like romance mixed with kink this AU is right for you. John and Rodney meet in college, get together and start a D/s relationship (with John as submissive). There are even two endings to choose from, one more fluffy, the other more angsty.
In the Nights When I am Lone, by Vain_glorious. Gen, John Sheppard, Ronon Dex. (2,768 words)
This is a sequel to the
Where The Ways Divide, a short role reversal story in which Sheppard is a runner and found by Ronon and his Satedan squad, which I have recced previously. This story explores some more how Sheppard might fare on Sateda.
Black Mountainside, by Whizzy. Slash, Rodney McKay/John Sheppard. (ca. 66,000 words)
I've recced the
Black Helicopters series before, but this new novel-length story has been posted since, so I thought I'd point it out again in case you missed it. In this AU Sheppard joined the SGC before Rodney, and then they meet when Sheppard crashes an alien craft in a test flight, and recruits Rodney.
Star Trek: Reboot
An Illogically Beautiful Mind, by Anonymous. Slash, Kirk/Spock. (ca. 5,100 words)
This is a fusion with Good Will Hunting.
A Little Left of Ordinary, by Anonymous. Slash, Kirk/Spock. WIP (ca. 6,300 words so far)
This one is a retelling of the movie in a vaguely steampunkish fantasy setting where magic also works. I really enjoy the worldbuilding so far.
Of Sentinels and Anchors, by Corpus Invictus. Slash, Kirk/Spock. (ca. 13,000 words)
The premise of this one is that Sarek died when Spock was young, so Amanda raised him on Earth and he lacks Vulcan training. As a result Spock has also problems controlling his telepathy. I really liked the Spock-angst and h/c. If you mind the "special mental bond" trope you might want to skip, but in that case Kirk/Spock is probably not your pairing anyway. I however have a soft spot for the same.
Nothing Lay Between, by Dancing Mercury and Jantra. Slash, Kirk/Spock, Pike/Spock. WIP (ca. 43,300 words so far)
Spock is given to Kirk by the Vulcans as a reward. The premise sounds as if it could only work if the setup is in alignment with your kinks, but this one actually has good worldbuilding, gradually gives background for the differences and isn't all that over the top when it comes to changing the characters.
The Hounds of Morrigan, by Hounds_morrigan. Het and slash, Kirk/Spock/Uhura. (ca. 20,000 words)
In this AU Nero was smart enough to destroy Vulcan, Earth and the Federation right away rather than wait for Spock to be able to gloat. The resulting apocafic universe is not that close to canon, but who could resist Uhura, Kirk, and Spock ending up as badass and somewhat traumatized crazy space pirates? It has the additional benefit of working for my slavefic kink and some others. On the flipside, if you don't share my fondness for a variety of non-con and power inequality kinks, you might not enjoy this as much.
Only Good for Legends, by Leupagus. Het and slash, Spock/Uhura and Kirk/Spock. WIP (ca. 19,300 words so far)
This takes place in the Star Trek universe, but Spock has become a police detective on Earth rather than joining Starfleet. I'm enjoying the worldbuilding and the bits of character background that have been revealed so far to explain the changes. It has some angst (the whole cynical detective aspect and some of Spock's backstory) but is also quite lighthearted and funny without being crack or parody.
Time's Divergence, by Logical_stimuli. Gen, Kirk, Spock Prime. (ca. 6,600 words)
This is domestic kidfic fluff that will make you feel warm and fuzzy: Spock comes through the wormhole at the same time as Nero, and because both of Kirk's parents are killed Spock raises Kirk.
Of Pilots And Groundbreaking Inventions, by Misfit_fandoms. Gen, Sulu (though the author labelled it as pre-Chekov/Sulu). (ca. 4,900 words) WIP?
The premise here is the Enterprise as a steampunk ship with an oddball crew. This feels more like a setup rather than an entire story, and the author said there might be more in this universe, but even as it is the atmosphere of this AU is neat and I enjoyed it as it is.
Twice Shy, by Sarka. Slash, Kirk/McCoy, implied Spock/Uhura. (ca. 20,000 words)
Bones is a werewolf, pining after Kirk. I never knew I wanted a Star Trek werewolf fic before reading this, but this was a fun scenario. It's a bit inconvenient to read posted as it is in a comment thread, and I hope the author will repost it elsewhere eventually. (eta: now available in in more
convenient format)
