Winterhawk fandom, do your thing
I mean if you're asking me to rec Winterhawk fic, I'm the worst possible person to do that, because I'm bad at bookmarking and my favorite fic tends to be whichever one I read most recently, but I guess I'll give it a shot. None of these are super recent (I haven't had much fic reading time lately) but they're all worth a read (and you should probably check out anything else by the author mentioned - I limited my self to one fic per author).
everything in my own library - read my fic! 😂
here's an old rec list I made several years ago so it's old as hell but I stand by my opinions

Feel free to add to this list, I know it's hopelessly outdated!
