Three years ago, when I first started looking for pirate stories on the internet, I ran across these vignettes by Amberlin on FF.net. They are Jack/Anamaria, and I still love them. They have a different, more innocent feel about them, have great characterizations, and are true to canon as I saw it back then. They may have been "jossed" by DMC, somewhat, but they are still very much worth reading. We don't get enough Jack/Anamaria these days. As the vignettes are no longer on Fanfiction.net, Amberlin very gave me permission to post them to Live Journal so I can rec and link them.
Here are the links:
