Wicked Game by planet_nasty_1
Fandoms: The Locked Tomb Series | Gideon the Ninth Series - Tamsyn Muir

Summary
Could it be that, despite years of hatred, Harrow and Gideon are actually falling in love?
Gideon looks soft, eyes slightly puffy from sleep and a pillowcase wrinkle pressed into her cheek. Despite the chill, she is wearing cargo shorts and a shirt reading “WENCHES DIG MY TRENCHES,” left behind by some long distant archaeologist girlfriend. Her hair glistens like copper and for an instant, Harrowhark is awestruck, faced by a golden-eyed god.
“Fuck, I gotta take a piss. Mornin’ night queen,” the god says. -

Summary
"What are you doing out here?" Harrow asked. She hadn't seen anyone else past the first few rows.
"That's a weird way to say thank you. And I'm drunk and eating cake, obviously."
"In the middle of the garden maze?"
"Yop. Guess we're both hiding."
Harrow wanted to protest that assumption, but she had just been witnessed crouching behind a statue.

Summary
Gideon is drunk at a party and needs to get his mind off getting rejected by girls. Ianthe begged Harrow to come to her party and somehow talked him into wearing a dress. Homosexual activities are bound to
I read PineAndPetrichor's "we're roommates. i use his condom after he uses it" and needed more Griddlehark as idiot gay boys. I don't want to talk about how I'm a lesbian and my first fanfic is a genderbend of a lesbian ship just let me indulge in smashing my gay action figures against eachother. The next fic will be very homosexual in the girl way. Also there's a hint at some gender stuff that I might expand on in later chapters. Right now I have two more as rough drafts and I plan on more though no promises.

Hey, Neighbor by royallyeffed

Summary
Like two eagles, claws so tightly dug into the other.
Spiraling, the world a blur around them, diving into something new.
Trust, the only thing keeping them from colliding with their inevitable end.
To save each other, to survive together—maybe this is what it feels like to fly.

“If you take the stairs, I’ll be offended,” Gideon remarked, still facing the elevator. Harrow heard the smile in her words nonetheless. She then did the dumbest thing she had ever done in her life: Harrowhark stepped away from the stairwell and joined Gideon in front of the elevator.
The silence hung thick in the air as the two women stood shoulder to shoulder. Harrowhark attempted to not notice how stark their height difference was, even despite the boost in height her boots gave her.
Gideon rocked back onto her heels and shook her hair out. An old habit, Harrow observed, one that she can remember so clearly. Memories came to her in a rush: metal bleachers, Gideon’s profile, the sun-rays illuminated behind red hair like a halo, sweat collecting on a top lip…
Old habits. Maybe this person wasn’t such a stranger to her after all.

Summary
Gideon would have held her breath and paused if by some miracle she managed to scrape together a do-over. Harrow probably would have, too, just to avoid having to say anything. Lapsed into a comfortable silence again with their fingers entwined the two of them could sit and stare and wait and wait and wait, witness their entire lives stretched elastic before them: St. Samael’s and the horror of the last week-and-a-half fading distantly into the horizon behind.
The stars currently floating above the elevator shaft were bright white and so sugary sweet they hurt Gideon’s teeth. No Southern Cross though— which sucked balls. She couldn’t really turn, either, to see if even a glimpse of it was visible from her second- (more likely third-) to-last resting place.
Okay, fine, pedantics: the place where Gideon Nav was most definitely going to die.

Summary
For Lyctors, the end is never near. So if you feel particularly keen on romancing the short lobotomized nun sharing your bed, well. You better not hold your breath. Or do it, who knows? You can't die anyways.
Harrowhark is haunted, Ianthe is horny and Mercymorn and Augustine are absolutely not having any of that.

Summary
Harrow was perfect; it was only natural for Gideon to respond in vitrail and follow her like a moth to flame.
Harrow only ever had eyes for bones. Or I just finished the second book and have a fun slight AU where the Reverend Daughter is blind except for seeing bones until she 'gets a new pair of eyes'

Summary
Gideon and Harrow are childhood friends using their university life to escape from their life spent growing up in a religious commune. Will they get together? (yes) How will they get together? (chapter 1) Will they stay together? (the rest of the fic) What will they think of the epic highs and lows of Canaan U's passionate rivalry with the College of the Blood of Eden that they settle on the basketball court? (read ahead to find out) Will there be cupcakes? (also yes)
Collection of stories from the students at Canaan University. Mainly focused on Gideon/Harrow and their relationship. Semi linear. This is my first time posting on AO3 and I am SCARED. Please feel free to suggest more shenanigans these goobers can get up to in the comments I love taking ideas and suggestions and turning them into fic chapters.

"Harrowhark, dear, we have got to get you laid."
or
After the worst breakup, Harrow is in desperate need of an outlet. Her annoying friend Dulcinea insists on trying an upscale escort service to work out the worst of her frustrations.

And then there's the security guard with the ridiculous hair.

Summary
Harrowhark Nonagesimus has come a long way from her sheltered Mormon upbringing. She's moved to the city, she's out, she has her dream job as a paleontology research associate at her favorite museum, she has friends, she's got a (begrudgingly alright) situationship that hasn't crashed and burned yet.
So why does she still feel like a fraud? And why do her thoughts always, inevitably return to the girl she abandoned more than a decade ago?
