These are for fandoms I follow but haven’t had much luck or time in finding goodies. This will be updated as I find more good things to share.
Buffy
Blood and Mistletoe (FF.net link)-Summary: Jilted with mingled feelings for the Slayer post the Will Be Done spell, Spike declares his feud with the Scoobies a Pax Romana for the holidays, and naturally ends up with a handful. [NC-17]
Dancing in the Moonlight (FF.net link) AU with Spike as a Slayer. [R for language and adult situations]
A Day Out-A cloudy day brings out the vamps (and Spike can shop!) [PG]
Three Vital Rules for Staying Stylish, Even (Especially) in a World Overrun by Monsters-Angel the TV Show. Very cute. [G]
Grey Gardens of Shadowed Rapture- Cross over with West Wing [NC-17]
Gardens of Crimson Roses-second in the Garden Club ‘verse [NC-17]
Sang et Ivoire-Diverges after Season 6. Interesting. [NC-17]
As The Romans Did-very interesting storyline set around Angel Season Five, Episode 22, but left unfinished. [T or PG-13]
Card Captor Sakura
Sakura’s Christmas Surprise Very cute story and treats the characters well and believably [T or PG-13]
Shadow of the Dragon Done by the same writer as Sakura’s Christmas Surprise, just as well done. [T or PG-13]
Cowboy Bebop
The Cowboy’s Unofficial Guide to the Open Road – Very interesting story. Road trip! [M] I want to read some more but have nary a clue to start looking!
Disney: Mulan
Deal With It- Shang isn’t stupid. He is perfectly aware that he is attracted to Fa Ping. [PG-13] (ZOMG Slash in a DISNEY movie!) I loved this-funny and really interesting!
Dr. Who
Marked – Ninth Doctor/Jack-Jack is the Doctor’s — he just needs a little reminding every now and then. [NC-17] I really should find some more goodies, especially in LJ land.
The Doctors. Rose becomes ill, so the Ninth Doctor and Jack take her to the person most likely to help her. [T, Jack's innuendo] S1 for Dr. Who, S3 for House.
Escaflowne
On Wings “A pawn’s place is on the chessboard until it’s captured, or the game is over.” Visions call a reluctant Hitomi to Gaea once more, only to find something drawing former companions back as well: Atlantis calls for its own. [T or PG-13] Not finished but shows great promise. I’ve not had much luck in finding other goodies in Escaflowne fandom.
Forever Knight
A Song for the Road. Nick goes back in time before he was turned. Very well written and it brought back all my love for the TV show. [G]
Fried Green Tomatoes
Wild Honey. An expansion of where Idgie goes to fetch Ruth from Bennett. Fried Green Tomatoes. Absolutely beautiful and filled with subtext. [K+ for swearing, implied fem-slash]
Good Omens
Human Footnotes – Adventures in the 1920′s, [PG] Really nicely done and makes me hungry for more. I really should pick up the book.
Jak and Daxter
Mechanic Girl-after Jak 2, Written to blend with canon, but prolly AU (or IS IT…). Very twisted! Keira shaped more of the post-Jak2 world than anyone knew. She shares her terrible secret with Tess via a journal. Fixes annoying canon plothole. [T, or PG-13]
One Piece
Turn On – The things Zoro loves. [PG-13] Very funny and well done!
PopSlash
Features members of either *NSYNC or Backstreet Boys or both bands together. I used to read fics back in 1997 for BSB and just now got interested in the fandom, mostly for the fic.
Hark. Joey and Chris are angels. Really cute, nothing graphic, and so adorable. [Joey/Chris, T]
Gratuity. Hookers and students and Lambs, oh my! [Lance/Justin, M] Really cute.
Sandman
The Visceral Latitudes – written for yuletide by dreaming_trees. I’ve not gotten very much into the Sandman fandom, but will once I read the graphic novel. But this is gorgoeusly written and doesn’t delve too much into canon, so an excellent introduction to the characters.
SGA
Freedom’s Just Another Word For Nothing Left To Lose. Beautiful. SGC finally stops calling him by December. Rodney celebrates by writing a final exam for his relativity class so difficult that it reduces four students to tears in the exam hall. Upon reflection, he decides to be merciful and offer partial credit. Part 1, Part 2 [T]
And The Band’s Playing “Hail to the Chief”. Ten Years after Freedom. Just as beautiful.
Slayers
H is for Hentai-the crew get sucked into a game world. Not finished and won’t be as the writer has gone on to concentrate on original fiction. Crossover with Ah! My Goddess! [PG-13]
Zelgadis on the Couch- Zel meets the woman of his dreams. The bad news is, she’s Xellos. The good news is, Lina and Amelia were spying on them. [R]
Zelgadis on the Road (sequel to Couch) It’s three days after their arrival in Seyruun, and Zelgadis, Princess Amelia, Lina Inverse and Gourry Gabriev are finally being allowed to visit Dr. Sorez’ tomb [R]
Smallville
Reconcilable Differences- My First dip into the waters of Smallville fandom. I swear DC writers smoke crack. 
[R-NC-17] I should finish reading this.
Sorcery and Cecelia
Portents of Magic and Might. Returning to London, Thomas and Kate are tossed into another magical mystery. Lovely and written in the style of the novels. [K+] Sorcery and Cecelia series. Wonderful stuff.
Spirited Away
Orpheus Descending- Ooh Greek mythology and an older Chihiro with just as much attitude as her younger self. [K or G]
Tsubasa Reservoir Chronicles
The White Tower- an interesting alternate view of the storyline. Nicely done by a former writer in the InuYasha fandom.
Weiß Kreuz
Dream of Crimson-AU, violence, character death, supernatural themes [R-NC-17]
West Wing
Hollow Lake State Park-Author’s Note: Just felt like briefly visiting these guys in the wake of the 2006 midterm elections. [G]
Yu Yu Hakusho
A Coin Worth Spending-nicely done OC but incomplete [T]
A Very Traditional Conversation-Kuwabara and Hiei have a man to man discussion regarding Yukina. [T]
