Alternate Career/Lifestyle (Sherlock)
(for internet-based AU, see below)
A Study in Squawking (Gen) by castiron. Parrot!Sherlock. I don't even know guys, but it's AWESOME. The autobiography of Sherlock Holmes, intelligent macaw, as told (under duress) to a therapist. AO3
Eyes of Sapphires, Smile of Pearls (PG) by
daisychains123. Cute AU in which Sherlock owns a jewelry store and John is a customer. Bonus Lestrade included. here on LJ
Ratiocination, or The Logic Behind the Perfect Coffee (Gen) by donutsweeper. Perfectly in character coffee chop AU. Barista!Sherlock is known for speaking to his customers bluntly, judging them by their orders, something John finds fascinating. here on LJ
{Sequels: Veridicality // Conviviality }
A Study in Pulling (NC-17) by flawedamythyst. Sherlock ran a website called The Science Of Seduction, on which he gave advice on the best ways to get laid, wrote blog entries detailing the results of his various sexual 'experiments' and generally contributed to the stereotype of 'every gay man is a sex-mad playboy'. John avoided the thing like the plague.
AU in which Sherlock treats sex like he does crime in canon. LJ | AO3
{Series: The Art of Seduction masterpost on LJ and AO3 }
The Thing That Happens To Other People (PG-13) by inkvoices. Sherlock is John's therapist. “Did you serve in Afghanistan or Iraq?” the man clarifies, steepling his fingers under his chin so that he looks like he’s praying for patience, and John reminds himself that he only has to attend six obligatory sessions with a psychiatrist. here on LJ
Alternate Career/Lifestyle (John or both)
(for internet-based AU, see below)
By Arthur Doyle (PG-13) by
agiddything. A clever, tongue-in-cheek take on the John-is-a-writer trope. John is a writer. Sherlock is a fictional character. here on LJ
Aptonyms (PG-13) by aheadofthecurve. Mr Sherlock Holmes and Dr John Watson are characters created by Sir Arthur Conan Doyle; Mr Sherlock Holmes and Dr John Watson are the unfortunate sods named after them. here on LJ
The Only Emperor (Gen) by coloredink. This is a completely believable ice cream shop AU, and made me fall in love with the characters all over again in their new venue. It never occurred to Sherlock Holmes that an ice cream shop might attract children. LJ | dreamwidth | AO3
The Orchard (NC-17) by dancinggrimm. Prostitution AU. “Now look, John,” Sherlock began, doing up his buttons. “This is very much not what I came here with the intention of doing.” “Oh?” John replied, puzzled. This was not, Sherlock admitted to himself, an unreasonable response. He had come to a brothel, he had recieved sex. To John’s average mind it must have made perfect, logical sense. AO3
Tornadogenesis (Gen) by imriebelow. Clever AU, set in the US though both S and J are still Brits. In which Sherlock is a genius forecaster, and John is an adrenaline-junkie expert storm-chaser. When they meet, chaos inevitably ensues. AO3
{Series: Vortex Breakdown }
Making The Connection (NC-17) by JessamyGriffith. John works for a phone sex hotline. Super hot, an not crack. It only started with phone sex.... Then it became something more. fanfic.net | AO3
A Study in Winning (NC-17) by
jupiter_ash. Easily the best thing since sliced bread: Sherlock tennis AU. John and Sherlock are professional tennis players and it’s Wimbledon. One is a broken almost was at the end of his career, the other an arrogant rising star tipped for greatness. It should have been a straightforward tournament. It really should have been. How were they to know that a chance encounter would change everything? LJ | AO3
Performance in a Leading Role (NC-17) by madlori. THE actor!AU epic. A must-read. Sherlock Holmes is an Oscar winner in the midst of a career slump. John Watson is an Everyman actor trapped in the rom-com ghetto. When they are cast as a gay couple in a new independent drama, will they surprise each other? Will their on-screen romance make its way into the real world? LJ | AO3
Murderous, Co-Dependent (Gen) by rageprufrock. As the person who recc'd this to me put it, this is " the ultimate John and Sherlock as animals" fic. Sherlock and John are Lestrade's cats. It's an uncomfortable and telling measure of the depth of Lestrade's parental guilt that he acquires not one, but two kittens. AO3
Untitled Forensics John Fic (PG) by stickstockstone. Forensics AU. What happens when John (who is the new head of forensics) meets Sherlock (...who is Sherlock)? "What in the fuck do you think you're doing?" here on LJ
{Sequel: The Inconsequential Death of Mr. Stevens }
Off on the Wrong Foot (NC-17) by unloyal_olio. Hot off the press! I can't shut up about how great this AU is. John and Sherlock aren't flatmates. Instead, John gets a job in Bart's morgue, and Sherlock attempts to abscond with body parts. Which is just not on. AO3
Meet Me Inside (NC-17) by wakeneve. A Prison AU that's somehow perfectly in character. John and Sherlock meet in prison. John becomes Sherlock's prison-wife. AO3
You've Begun to Feel Like Home (R) by yalublyutebya. Another fandom classic, in which John is a Catholic priest. Note: heed the warnings, but don't let them scare you off; this fic has more than earned its great reputation. Sherlock Holmes is everything Father John Watson should probably disapprove of. He's an atheist, a rationalist, an addict, and gay. But none of those things is enough to stop him from being the most fascinating person John's ever met. LJ | AO3
{Sequels: Where Hearts Are Sure // Too Close to Home }
Five Drinks Sherlock Turned Down, and One He Didn't (PG) by anonymous. John runs a bar. Sherlock is the newest customer. on the meme
Alternate Timeline
The Sign of Three (Gen) by emungere. Mycroft takes his little brother to the park, where they meet John and pretend to be pirates. AO3
Welcome Back (NC-17) by lamb_fic. Sherlock and John are in a relationship before John leaves for Afghanistan. John wrapped his arms around Sherlock, drawing soothing circles on his back, “When I come back, you’re going to have to move into a bigger place, I’m not living here. Can’t breathe here without knocking down an experiment.” Sherlock held on tighter, but the taxi honked and John pulled himself away. here on LJ
That Certain Night (R) by lotherington. The first in lotherington's epic series of WWII AUs, John follows Sherlock home after a chance encounter. ‘Are you in the habit of inviting queer men back to your flat, John?’ he murmured, his eyes half-lidded as he stared at John again. John huffed a breath through his nose. ‘None quite so peculiar as you,’ he said after a long pause, lifting his eyes to Sherlock’s. LJ | AO3
{Series: Long Ago And Far Away, masterpost on LJ and AO3 }
The Dangerous Book for Boys (PG-13) by
orange_crushed. Classic high school AU, with bonus casefic! LJ | AO3
Let's Make A Bed Out In The Rain (R) by theimprobable1. So good. John moves in with Sherlock after breaking up with his long-term girlfriend. John is devastated after his girlfriend leaves him. Sherlock helps him through it. LJ | AO3
A Study in Blue (PG-13) by TheShoelessOne. On 1st January, 1920, John Watson meets Sherlock Holmes. Jazz Age AU, eventual John/Sherlock. fanfic.net
Fairytale of London (PG-13) by thirdbird. How would things have been different if John and Sherlock had met earlier? In my opinion, thirdbird has the real story. What if John and Sherlock had met five years earlier? dreamwidth | AO3
{Sequels: The Correspondence // The Damage Done }
Arranged Marriage
The Pull of One Magnet to Another (R) by ellie_hell. A fandom classic. Mummy has arranged Mycroft’s marriage with an ex-army doctor. However, John meets Sherlock first, and sparks fly. AO3
The Engagement (NC-17) by thedeadparrot. Also royalty! AU. For political reasons, King Mycroft has his younger brother, Prince Sherlock, betrothed to a foreigner, Prince John. Sherlock is not pleased. here on LJ
BDSM world
You Need Someone (but it won't be me) (NC-17) by etothepii. Sherlock/Lestrade, sequels Sherlock/John. The first time he sees Sherlock's driving license, Lestrade is sure it's a skilled forgery, though why Sherlock would want the little black S as his role instead of a D, he has no idea. here on LJ
{Sequels: it's easy to trust someone who can't break you // everything you won't tell me (is mapped in your scars) }
The Great Amendment of 1998 (NC-17) by ihuntyoudown. Long and thinky, with excellent world building. In a world where everybody is a dom or a sub, John pretends to be a dom, but he isn't. dreamwidth | AO3
{Sequels: Vengeance Is Mine! // Moods }
If I Fell (NC-17) by thedeadparrot. Not BSDM world per se, but so good I had to include it. Sherlock knows that John sleeps with men. That much is obvious. What Sherlock doesn't know is whether or not John likes to fuck them or be fucked or if he likes to pull hair or leave teethmarks or if he likes being on his knees or if he likes forcing people onto their backs. Sherlock doesn't know if John wants to fuck Sherlock, of all people. LJ | AO3
The Pleasure-Dome Hotel (NC-17) by raiining and velvet_mace. Extraordinary, brilliant, amazing are just a few words one might use to describe this fic. Sherlock. Mycroft was paying for the whole thing, Sherlock's brain informed him. If he left without making full use of the hotel's services, it would be saving Mycroft half the bill. That would never do. Warnings for prostitute!John LJ | AO3
{Sequel: Once Collared by xixie and your_icequeen }
I Could Make Your Whole World Sweet (NC-17) by wallhaditcoming. AU in which everyone is either a dom, sub or switch. “An old friend of mine, John Watson,” Mike remarked from his position on the sidelines. Sherlock’s eyes darted over the man and he allowed himself a small internal sigh of disappointment. Hair-cut and bearing said military. Statistics and his refusal to back down from Sherlock’s stare said Dom. A pity. here on LJ
Cabin Pressure
Hunger Pangs (NC-17) by keelywolfe. So, so sad and so good. Warning for prostitution. It'd been years since Martin had been that desperate, desperate enough to consider just what he would do to get a bit of money. John/Martin. here on LJ
The End of the Road (PG-13) by theimprobable1. A post-TRF tear jerker, but with a happy ending. After Sherlock's death at the Reichenbach falls, John finds solace with an airline captain who bears an uncanny resemblance to the detective. Sequel is Cabin Pressure only. here on LJ
{Sequel: The End of the Day }
Canon (includes ACD, Granada and Ritchie)
Echoes Through Time (NC-17) by chellefic. Lovely ACD crossover, chellefic masters the period writing style perfectly. Mummy sends a trunk from the Holmes cottage in Sussex to 221B. Its contents alter the way John and Sherlock see themselves and one another. AO3
The Red String (PG-13) by Tora II. In which The Adventure of the Three Garridebs ends quite differently and Sherlock Holmes makes a wish. Also a crossover with xxxholic. fanfic.net
Untitled Fill (NC-17) by anonymous. RDJ! Holmes travels to the future and seduces an overwhelmed BBC!John. The worst week of Sherlock Holmes’ life started when Lestrade called him and John and asked them to come to Scotland Yard. Sitting in his office, Lestrade explained, ‘We’ve got a man down in the cells who claims he’s Sherlock Holmes.’ on the meme
Doctor Who (includes Torchwood)
Captain John Watson, Genetics, and Other Crazy Things (R) by cyerus. This is hilarious. The explanation for John "Three Continents" Watson? Jack Harkness is his father. Sherlock doesn't know whether he's going to die from jealousy or sexual frustration first. here on LJ
Temps (Gen) by humantales. John and Sherlock join the Torchwood team following TGG. Torchwood is down a technical specialist and a doctor. Mycroft is trying to keep a genius and a doctor safe from Moriarty without having to spend too much on repairing the damage that a bored, imprisoned Sherlock can cause to a safe house. The government wants Torchwood to hire replacements, but Jack isn't ready to replace Owen and Toshiko. AO3
The Detective (PG) by
lotherington. Adorable Doctor Who crossover. John Watson was seven years and three months old when he first met His Raggedy Detective. He wasn’t expecting the bright red telephone box to crash land in his back garden in the middle of the night, but then, who ever expected such a silly thing to happen in the first place? LJ | AO3
Two Doctors, A Nurse, A Detective and A Scot (PG) by TheShoelessOne. Sooo sweet. First a deliciously long series of fic. "Look, I'll be out of your hair soon as I find my friend," the short man tells him, craning his neck here and there. "Tall bloke, lots of curls, stinks of ego. Probably off somewhere pulling wires out of the wall." To his credit, Rory doesn't panic. Much. "That's. That's really not good." fanfic.net
{Author's Masterpost lists all seven fics in the series)
Harry Potter
Whispers In Corners (R) by esama. An amazing HP crossover with an interestingly apathetic Harry and a sexy, mysterious Mycroft. Everything started with a stumble - his new life in a new world as well as his surprisingly successful career as a medium. fanfic.net
The Mirror of Erised (Gen) by missilemuse. Cracky fluff, so enjoyable. Mycroft finds the Mirror of Erised; and a convenient sample group. Enter Sherlock and Co.! So what’s your heart’s deepest desire? LJ | fanfic.net | AO3
The Case of the Unwelcome Owl (PG) by pandarus. I'm dying for a sequel to this adorable, hilarious little fic, in which Luna is Sherlock's cousin. There was a medium-sized barn owl in the living room, perching on the back of the sofa. It didn't seem to be showing any immediate signs of being a ninja owl assassin working for an evil genius; on the other hand, John hadn't the faintest idea what on earth had led it to come and sit on furniture in the middle of 221B Baker Street. here on LJ
The Almost Empty House (PG) by rachelindeed. Sherlock Holmes and John Watson are on their way to Hogwarts. Sherlock is determined to live in an empty House, but things don't quite work out according to plan. here on LJ
{Sequel: Further Adventures of the Hogwarts Irregulars }
His Dark Materials
The Republic of Heaven (NC-17 eventually) by blind_author. A complex, plotty WIP, well worth following. Born to a witch and a human, people know Sherlock will be unusual from the start. John Watson, on the other hand, seems perfectly ordinary, except for his dæmon... LJ | fanfic.net
Traditional (Gen) by dameruth. A Holmesian Christmas dinner, with daemons. AO3
{Sequel: Auld Acquaintance }
Highly Intelligent, Observant, and Destructive When Bored (PG-13) by etothepii. This His Dark Materials crossover is actually the second fic in the series, but I recommend reading it out of order for the mystery. "I wonder what his daemon is," Kaliope says, when they're in bed waiting to fall asleep. "Do you think she doesn't like us?"
Eventual Sherlock/John/Mycroft. LJ | AO3
{Sequel: Feels Like Drowning; Prequel: Asteroidea }
Panes of Glass (Gen) by justwolf. Sherlock has an alethiometer. John is worried. Normal people don't keep an alethiometer in their pocket next to their keys and their phone. AO3
{Sequel: Whiskey and Take-Away }
Internet AU (includes gamer, internet dating, fandom, etc.)
The Internet Is Not Just For Porn (PG) by cyerus. John is Sherlock's internet boyfriend - from Canada. "Sherlock," Lestrade said carefully, "exactly how did you meet, uh, John?" "Over the internet." The poignant silence from before was back, along with its friends Awkward and Holy Fuck. here on LJ
The Dangerous Edge of Things aka Sherlock has a boyfriend who lives in Canada (PG-13) by dreamingrain. Another long fill from the prompt above, with clever use of emails/texts. LJ | AO3
{Fic masterpost on LJ; Extra: We See Thee Rise }
Level 65 Paladin Looking for Group (PG-13) by etothepii. Gamer AU. "I think I met someone," John says at his next therapist's appointment. "A friend." "Really?" Ella asks. She sounds pleased, and also surprised. "What's his name?" John nods. "Really. His name's Sherlock. He -- he plays the same game as me, the online one. We party together." Dreamwidth | AO3
The Theory of Narrative Causality (PG-13) by
falling_voices. The one. The only. Sherlock and John are BNFs in Sherlock Holmes fandom. Together, they fight crime. (Always.) And write porn, incidentally. here on LJ
LOTR & The Hobbit
Here There Be Dragons (R) by emotionanalysis. Crossover with The Hobbit. When John makes a bet with his friends to go and find the rumoured dragon of the mountain, he gets a dragonful more than he bargained for. Warning for mythic bestiality. here on LJ
A Scandal in Auenland (Gen) by OneMadCookie. Rare LOTR crossover, definitely a WIP to watch. One particularly arrogant wizard and one jam-loving Hobbit. When two worlds collide, a new one will be born. Fluff, comedy and adventure lie ahead! fanfic. net
Unexpected Journeys (PG-13) by story_monger. Slightly cracky crossover with The Hobbit. Looking back, John wasn’t really sure why he’d thought it was a good idea to get a flatshare with a dragon. here on LJ
Magic & Special Powers (for X-men powers see below)
The Shadowman (R) by ambikai. Written from the disturbing (yet strangely sweet) POV of soul-eating monster!Sherlock. Sherlock is a shadow, melting into the dark and consuming souls. Then John came along, human and so very bright. LJ | fanfic.net | AO3
Cost of Living (R) by americanjedi. Creepy, atmospheric post-TRF fic with monster!John. John Watson's family has always been a little different. He never thought about it until Sherlock died. Now John is running through dreams collecting hearts. here on LJ
Shadows on the Wall (PG-13) by aramuin (AraSigryn on AO3). So good! This fic will keep you on the edge of your seat. John comes back from Afghanistan psychic. AO3
The World on His Wrist (PG-13) by bendingsignpost. UN-freaking-BELIEVABLE time-travel AU. Makes me wish copyright would die so this could be published. First, he is shot in Afghanistan. Second, he wakes to a phone call in Chelmsford, Essex. Third is pain, fourth is normalcy, fifth is agony and sixth is confusion. By the eighth, he's lost track. LJ | AO3
{Series: Watches 'Verse }
Gone Is My Past (PG-13) by cyerus. People in this fandom are so creative, it's astounding. John is an army bomb detection dog who has been turned into a human. Angst. here on LJ
They Tell Me Their Secrets (Will You Tell Me Yours Too?) (Gen) by etothepii. John can talk to inanimate objects. Brilliant. In Afghanistan, the supplies tell him when they're running low, and the cars always, always tell him when strangers have touched them, and John gets known as having a knack (paranoia, his men call it, but he's never missed a single car bomb) for keeping his men safe. LJ | AO3
Quercus Robur (PG) by kikainausagi. One day John Watson turned into a tree. Touching and (somewhat surprisingly) not crack. LJ | AO3
A City On The Head Of A Pin (PG-13) by mad_maudlin. After the events of TGG, John gains a special ability. When John first woke up, he could that he was on powerful narcotics. Thus he was not at all bothered that the technician recording his vital signs was sporting a large pair of glossy white wings. LJ | AO3
A Mile in His Shoes (NC-17) by mamfidd. John and Sherlock swap bodies. Hijinks (yes, that is a euphamism) ensue. here on LJ
Time In Lieu Of (PG-13 ?) by squidwhisk. Cracky, excellent. John Watson has three siblings, not one...and together they are the four horsemen of the Apocalypse. here on LJ
Untitled Fill (Gen) by anonymous. A teensy, yet irresistible crackfill. BAMF!John punches Death. on the meme
John's Midnight Garden (PG-13? maybe?) by anonymous. John meets Sherlock in his dreams. For as long as John can remember he has dreamt of the garden. on the meme
Magical Creatures (for vampires and werewolves see below)
Faerie-Touched (PG-13) by blind_author. Fairy AU. In a world of sorcerers and magic, Sherlock is a Faerie-born and John, lacking any kind of magical talent, often seems a bit out of place. But he has a gift all his own... LJ | fanfic.net
Crossroads (PG-13) by keep_counting. Sort of Supernatural crossover, but works on it's own. Summon a demon by the crossroad, and get all your hearts desires. For a price, of course. here on LJ
Human For A While (NC-17) by fengirl88. Beautiful, angsty fic with Selkie!Sherlock. John comes home from a trip to the seaside with a pale-eyed young man in tow. Sherlock is tall, brilliant, and strangely sad, and seems incapable of leaving John's side. One day John brings a seal skin to Harry's house and makes her promise to hide it, and that she will never, ever tell Sherlock where it is. here on LJ
The Scent of Sherlock (PG) by heeroluva. John is part pooka. Sherlock is...well, let's not spoil that. here on LJ
I Know Thee, Stranger (PG-13) by
lotherington. Cuz there can never be enough lotherington recs. Archangel AU. ‘They’ve even accounted for dinosaurs, for goodness’ sake, and they were meant as a bit of a joke when we all got pissed that one afternoon.’ It’s 2010. Sherlock is bored. Mycroft is exasperated. Gabriel’s tired. Raphael’s missing. LJ | AO3
How To Accidentally Summon a Demon (PG) by patster223. Sherlock, John, and a demon. Sherlock is possessed by some sort of demon. It is not an absolutely evil creature, but it is definitely twisted and wicked and damned. John doesn't even notice the difference. here on LJ
Virgins Lure the Creatures (Gen) by shenaniganders. So Sherlock is a virgin. And it doesn't bother him. Why should it? If only it weren't for those damn unicorns! Short crackfill. on the meme
Splash (PG-13) by sostrangechild. Merman!John. In which John is pushed into the water, and Sherlock's brain exits left. on the meme
The Letter of the Lore (PG) by anonymous. Sherlock may be a faerie, but even faeries have rules to follow. The law is easily broken, bent and twisted. Its only enforcers are mortal and limited by the constraints of physics and the very thing they uphold. But the Lore: that is unbreakable, unbendable. on the meme
You Give Death a Bad Name (PG) by anonymous. Zombie!Sherlock. When Sherlock wakes, it’s Mycroft’s face he sees, bent and hovering over him like a branch from a weeping willow, blocking the artificial lighting and trapping Sherlock within Mycroft’s overbearing presence. on the meme
MPreg & Omegaverse
Two Words, Ten Letters (PG-13) by dorothydonne. John/Mycroft with John MPreg. There are no symptoms. None. Well, the nausea. But that’s the flu. People get the flu. Everyone gets the flu. I don’t get pregnant. AO3
Mummy, No Thank You (NC-17) by unloyal_olio. The fic that finally made me understand the appeal of Omega!verse. Mummy Holmes arranges a marriage for Sherlock.

Sherlock and John get along fine, but Sherlock refuses to marry and breed. Mummy decides that John should marry and breed with Mycroft if Sherlock doesn't want to. Sherlock is not happy at all. AO3
If You Can't Stand the Heat (NC-17) by velvet_mace. Moving with excellent world-building and perfect characterization. WIP. The omega was good at hiding his scent. Anyone other than Sherlock would have missed it, and as it was, Sherlock nearly did himself. Sherlock/John, eventual Mystrade. on the meme
Other Book crossovers
The Crown Princess of Gaaldine (PG-13) by AJ Hall. Part of a long series set in Gondal, a fictional world invented by the Brontë children, this fic features some of the best original characters I have ever read in fandom. The dying King of Gondal lays a solemn trust on John Watson, court physician: at all costs to keep the fourteen year-old Crown Princess Charis out of the clutches of the corrupt Heir of Gondal. Which means arranging her marriage to Sherlock, heir to the neighbouring throne of Gaaldine, Gondal's traditional enemy. AO3
{Series: Queen of Gondal Universe }
Equilibrium (R) by augustbird. THIS FIC. IT MUST BE READ. At Baskerville, John is infected by a virus that turns him into a genius. But when the infection progresses into neurodegeneration, it's a race against time to save himself. Flowers for Algernon fusion. AO3
The Beast Not Found in Verse (Gen) by coloredink. I love this Beauty and the Beast crossover to distraction. READ NOW. He wasn't sure if he was more shocked that the creature talked, or that it spoke the Queen's English. AO3
A Secret Doubt (PG) by life_downsized. Sad, moving and so heartbreakingly real. Tinker Tailor Soldier Spy crossover. When Sherlock is five, his Uncle Peter shows him how to conjure a coin from behind his ear, installing in the child a desire to unlock the wonders of the universe. Sherlock believes himself to have found a hero in his relative. Over time, this ideology is sorely tested by circumstance, and a strange man called George Smiley. here on LJ

Other TV/Movie crossovers
Synthetic (PG-13) by aslipperysloth. Lovely but hard-hitting Blade Runner crossover. Get the tissues ready. John is the best blade runner ever to have worked for the London police. Mycroft calls him out of seclusion to track down and retire one especially slippery replicant that used to be an invaluable asset to them in solving crimes, but over time began to believe that it was human. This replicant’s mind has deteriorated to the point where it now believes that Mycroft is its brother, and that it is a consulting detective. here on LJ
Sic Gorgiamus Allos Subjectatos Nunc (PG-13) by etothepii. I'm not any kind of Addam's Family fan, but this crossover (and its two sequels) is my absolute favorite fic bar none in the fandom. What are you waiting for? "Sic gorgiamus allos subjectatos nunc. It's the family motto." "What does it mean?" "We gladly feast on those who would subdue us." LJ | AO3
{Sequels: Woe and Arachnids // Your Body Before Me }
Quick Like a Bunny (PG-13) by
innie_darling. Sherlock/Queer Eye crossover. Only one of many brilliant fics by innie_darling, don't stop with this one. All five of the men were smiling at him, gleaming sets of American teeth; it was like shark week right there in his flat. LJ | AO3
Nothing We Could Judge (NC-17) by green_postit. Inception crossover. Eames is Sherlock's college roommate. "Exactly how long have you resented your brother?" Eames finally replies crisply. He watches the ripple in Sherlock's spine with a satisfied, smug smirk. here on LJ
VIP (Gen) by lindentreeisle. Crossover with the 2009 movie Push, first in a series. John shrugs. It's not like he hasn't met Assets before; not like they can tell he's one of them, unregistered and untapped, just by looking. All he has to do is act normal and he's fine, like always. He's not letting Bill's rampant paranoia infect him. AO3
{Series: Push!verse }
John Watson, Bachelor (NC-17 eventually) by rayonea. Yes, a Bachelor crossover. No, you should not run screaming. Read this, it's great. For those of you who aren't up-to-date on their Reality TV schedules, Monday night is The Bachelor night. This season, John Watson is the bachelor. Every Monday evening, there is a new episode. Tonight is the beginning of our journey. here on LJ
{Fic masterpost, as chapter links were iffy last I checked }
The New Hire (PG-13) by anonymous. Sherlock is the newest employee of Wernham Hogg. Crossover with The Office. on the meme
Untitled (R) by anonymous. Project Runway crossover. Sadly, this fill looks to be abandoned...but it's brilliant, fun and still very worth reading. And that's saying something. "The judges let you into the competition because of your simple, clean lines. But this. Dear god." Tim glowered at Sherlock, gesturing at the mannequin swaddled in black chiffon and lace. "That's just the hat." Sherlock continued snipping away at the fabric. on the meme

Two Of A Kind (R) by argyle4eva. The first in a lovely, long series. Sherlock's a Vampire. John's a werewolf. Together they fight crime. AO3
{Series: Being Sherlock }
Stranger at the Gate (NC-17) by bendingsignpost. This is...so amazing, I'm without words. Go. Read. Burn Twilight from your memories.

On a side note, bendingsignpost has a new fic with Vampire!John for a change. Still WIP, but I'm so excited: Nine Tenths of the Law
My Body When It Is With Your (NC-17) by mad_maudlin. First in a series. Lupercalia: the season when the werewolf takes a mate. John is unhappy. Sherlock is intrigued. AO3
{Series: Lupercalia verse }
A Priori (R) by rubberbutton. A wonderfully chilling look at vampiric slavery. In which vampires have enslaved humans and control, well, everything. Vampire!Mycroft insists his little brother get a slave -- even though it didn't work out with the dog -- and Sherlock chooses the one guaranteed to irritate his brother the most: an unassuming little doctor with an ugly past and absolutely no style to speak of. AO3
{Sequels: White Noise // Symbiosis }
Mate (NC-17) by velvet_mace. Mycroft has his life and ambitions pretty much order: First set his errant brother straight, next take over the world. But to do the former seems impossible, while the latter requires that he find a mate -- a rare human whose blood is capable of helping him create vampires. Both his answers come in the shape of one man: Detective Inspector Gregory Lestrade. The problem? Mates can't be forced and Lestrade has no interest in becoming Mycroft's. LJ | AO3
