Uh, regarding POTS I know some people who swear by Fallen, in which Kel becomes a Tortallan spy in Scanra after Wyldon forbids her from staying on as a page. It’s very plot-heavy, so give it a few chapters before judging it.
Otherwise, I don’t really subscribe to ff.net as a place of quality TP fanfic, haha. You could browse The King’s Own, they have a pretty good collection.
And thank you so much :)
