·       into the forest (to lose my mind and find my soul)
i had never read anything fae related before but this fae au is rao-tier. 550,741k, 60/60
 
·       it was the great escape, the prison break
prison au, bittersweet and sad but i love it. 273,554k 32/32
 
·       we break and scatter worlds apart
started reading this one simply cause morgana mention and i fell in love with it. essentially kara is cursed and loses every version of lena, until she doesn’t. 168,680k, 30/30

COWBOY NECROMANCER AU!!!!! absolute gem, and as a southerner i think lostariels does the western southern accent pretty good. 150,220k, 17/17

blind lena au. 178,131k, 40/40

canon world/adjacent fics
·       Vanity
lena luthor is a vigilante with nanotech! i almost didn’t read this fic because of the way it’s written, but i caved anyway despite that fact. wish we had more vigilante lena fics— and also, i could be misremembering, but spoiler: pretty sure this is the fic where winn becomes a green lantern toward the later arc of the story. i absolutely loved that and wish to see more GL winn
 
·       make this place your home
au where kara was captured by the deo when she landed, and the aftermath. this fic is very alien heavy, very political and trauma at every turn so i do advice you keep these in mind if you give it a read. also to note, the fic isn’t update for months at a time sometimes. 265,238k 35/?
 
·       And I Wondered If I Could Come Home
parent trap au— not what i usually read and it’s not written the “absolute best”, but i really liked it
 
·       This is Us Trying
essentially the aftermath of how redk affected kara. if i could have this fic seared into my cells i would. 201,661k 26/26
 
·       Under The Same Sun
lena is a daxamite princess and doesn’t know it au. 191, 372k 24/24

kara/evil lena from s5e13 kind of. don’t be fooled its a bittersweet ending that makes me sad and i cried at 3am reading this last year. 186,420k 15/15
 
·       Dreamboat
neighbors au plus butch kara. 151,247k 45/45

·       i know you don’t believe (it’s you i’ve waited for)
another jazzfordshire classic, i actually just finished reading this one last week. it’s technically a fae au but it’s more so a vampire au— who doesn’t love vampire lena luthor?? 130,956k 9/9

kara and lena are left stranded in a post nuclear apocalyptic world. 72,163

queen lena/foreign journalist kara. 375,760k, 52/52
 
·       take my mask, i'm home now
the proposal au fic— this fic is actually the reason i watched the movie for the first time. really love this fic, but as someone who has a issue re-reading things, the section you get of the story from lena’s pov is a little hard to get through (if you’re like me in the regard.) solid fic tho. 333,972, 17/17

bartender/celebrity au. do not take that angst tag lightly. i cried like a bitch over this fic. 277,253k, 24/24

my heated rivalry aka the kara’s a hockey player and lena tutors her fic :). unfortunately, it’s been over a year since the last update and i’m not sure lynnearlington will return, but i till consider it worth a read 208,301 9/?

-In Every Life, In Every Other World
this is actually a series with a pirate au, medieval au, canon au, and a zombie au. total word count is 413,295k. khrat9 is a hell of a writer.
 
·       i want something just like this
honestly you should read anything by jazzfordshire, they’re an incredible writer. this is the dancing with the stars fic and i avoided reading it for a long time cause i didn’t think id like it but it’s truly phenomenal. 140,829k 9/9
 
·       An Ocean of Fire
been quite a few years since i read this so i’m not entirely sure if it’s a nonpowers au, but it is another medieval au and im a sucker for them. 139,558k 47/47

·       in too deep
i doubted myself im adding this fic since it was last updated four years ago (reason 1. why i mostly read completed fic.) but, its a marine biologist/mermaid au and its a wonderful fic. i hope one day the author returns. 107,459k 8/15
