I’ll sound like a broken record if I say Some Things Last again, so I’ll talk about my second favorite.
Under the Surface. (AKA Dean gets captured a whole fucking lot.) It’s a destiel, fantasy-ish, pirate au. Because you know what’s awesome? Pirate Captain!Cas, that’s what’s awesome. I actually had a lot of fun writing this fic and I got to be really nerdy about pirates! I spent a lot of time thinking about it and how to do it and what would work. It’s Prince!Dean, Pirate!Cas, kidnapping, pirate battles, adventure, stargazing, and a smidge of political/monarchical stuff. I don’t want to give too much away because I actually like the way it evolved but I think if you like aus that are less “romance” and more “falling in love and oh, shit, we’ve got a problem” I think you’ll like it. I know I did. (And the ending is cheesy.)
My favorite fic by someone else? Absolute favorite?
Put Up Your Dukes by saltyfeathers. (Destiel, canon verse)
Dean’s got enough neurotic shit goin’ on in this fic to last me a life time, but what really sold me was chapter four. Like, holy shit. Dean gives this whole long, rambling explanation about parallels and it’s the funniest fuckin’ thing I’ve read in a long time. Also, shout out to Sam for being the most patient dude in the whole universe, and for the line “Do I get the bedroom eyes for not using my radio, too?” It’s such a good fic and it includes a lot of my favorite things, too. (Dean being anxious about all kinds of shit, Cas being a sassy and clever fucker, and Sam being a loving little brother but a little brother none the less.) It’s also got a neat monster!
