I've been reading a fair bit of One Piece fan fiction recently so it seemed right to start a rec list for this fandom as well. Here you'll find a rather eclectic selection of recs - and my preferred characters tend to be Luffy, Ace, and Shanks, which shows in the list. Where pairings are concerned I'll give anything a try, and thematically I do have a tendancy towards dark and angst, but I have no problems with a bit of fluff and humour as well.
In summary: expect anything to pop up on here.
Where the list is concerned I just provide whatever rating and summary that the Author posted with the fic.
