Ooh. This is going to be 100% Capaldi-character fic, because Twelve/Clara is the pairing that got me back into fandom after more than two years away. I fired up the browser & went looking for fic after they snagged me hard. Then I branched out & followed the PCap trail into other shows; hijinx ensued.
I just popped up about 10 stories that I’d re-read happily on a deserted island with my 10 records. Whittling it down to 5 is going to be tough.
Top 5 fanfics I read in 2014 (not necessarily written in 2014):
“With-holding” by silverarrow (Twelve/Clara)
“About Last Night” by kittenmommy (Twelve/Clara)
“In the middle before I knew” by jontinf (Twelve/Clara)
“Get your mouth open” by levendis (Twelve/Clara)
“Life During Wartime” by Aramley (Malcolm Tucker & CJ Cregg)
That fifth story — an utterly natural West Wing crossover— leapt to mind the instant I saw your question. Had to be on the list. So good.
Okay, fuckit, cheating with honorable mention “Promises, Promises (Explosions, Explosions)” by RandomBattlecry.
Oooh, some of these i have not read so I will check them out!
