There is so much fantastic fic being written in the Sherlock fandom it's almost impossible to keep up!
The Paradox series by
wordstrings An Act of Charity,
The Paradox Suite,
The Death and Resurrection of the English Language and
Entirely Covered in Your Invisible Name This series as a whole is absolutely stunning and some of the best fan fic I've ever read. I love the author's depiction of the Sherlock/John relationship. Its warped and unhealthy and hideously co-dependent and yet curiously sweet and touching at the same time. Brilliant characterisation (Sherlock is absolutely terrfying and sweet and awkward and brilliant all at the same time) and an impressive bit of world building makes for one of the strongest series in the fandom. Some minor americanisms creep through ("cream and sugar" - Donovan shooting someone in The Paradox Suite even though in reality a DS wouldn't have a gun, Sherlock rather incongruously saying "son of a bitch" that sort of thing) and Lestrade's name is Greg not Geoff (Gatiss tweeted categorically on that point) but they're minor quibbles. Fantastic stuff.
It feels like home when I'm with you by
etothepii Fantastic engrossing story featuring John as a ghost. When I read the summary I thought it would be rather silly but its very well plotted and characterised and the Sherlock/John relationship is rather sweet.
Monster by
Moony In the wake of the events of The Great Game Sherlock turns criminal. Or does he? A gripping, superbly plotted story which keeps you guessing throughout as to Sherlock's true motivations.
The Shape I Found You In by
irisbleufic and
moony Sherlock investigates a case in Sweden whilst John realises that absence makes the heart grow fonder. Really lovely, slow moving fic with the gradual realisation of the characters feelings for each other playing out in a way which feels entirely true and believable. The texts and e-mails that form part of the story are at turns funny and heartbreaking and even the tertiary characters are well realised. Wonderful.
Shift by
messageredacted More of a gen rec this one as Sherlock has to race against time to save the intended victims of a sniper loose in central London. Fast paced and tense with great characterisation.
House Rules by
nishi_shinji Hilarious and fluffy piece as Sherlock and John try to come up with the house rules for sharing a flat together.
Highly Intelligent, Observant and Destructive when Bored,
Feels Like Drowning and
Asteroidea by
etothepii (Whilst Asteroidea is the first in the series it can (and should) be read last if you don't want a major plot point revealed - Feels like Drowning is John/Sherlock/Mycroft)
Brilliant His Dark Materials cross over. I've never really cared for crossovers but the concept of daemons fits effortlessly into the world of Sherlock and the world created in these stories is so richly realised. Really lovely writing which left me wanting more. Also I completely didn't see the twist coming. Very well done.
