Oooo! I read and write Potc fanfic. The best way is to go to fanficion.net and go to the pirates of the caribbean section. After the title is a summery and so it's easier to find what you want. You can also narrow your search by saying you only want fics in a curtain genre or with a curtain character.
I have a story there to and I think it is rather good. It might be a little emotional but it's a tragedy. This is the summary.
On there way back from their failed quest to bring Jack back, Betrayal brings more than just sadness to Liz’s existence. It ends hope of a happy life “Waves didn’t have to feel pain. Waves could roam the sea freely and not worry about emotion."
Here’s the address,
