Summary
Nona is seven months old when she stops having the salt water dream. Gone is the painted face. Gone are the arms around her, squeezing. Her subconscious fishes for replacement material; it finds things she doesn’t want to remember in the morning.
Nona(?), Pyrrha, and a kinder method of consumption.

Summary
On second glance, Gideon realised it wasn’t quite accurate to describe the Sixth as equally grey-wrapped. As she edged around the corner and the pair came into better view, she saw the necromancer’s trousers were around his skinny ankles, and the cavalier’s mouth was wrapped around his—
Gideon needed to lie down.
(AU where the Nine Houses interpret “one flesh, one end” in the “free-use cavaliers” sense. If only someone had warned Gideon before she agreed to pose as Harrow’s…)

seventh!cam AU by arithmonym

Summary
Camilla Hept didn’t let go. It was her one thing. Growing up on the Seventh House, a House with a fatal longing for the picturesque — a House incapable of half measures — why should that surprise anyone, least of all herself?
AU where Cam is Dulcie’s cavalier instead of Pal’s (and it only worsens her self-sacrificial tendencies).

Summary
Gideon Nav is the defensewoman New York needed, although she prefers defensebutch, thanks. Six feet of absolute dynamite on the ice, with a weapons-grade slapper and smothering shutdown play. And she's finally free, a year ahead of you-know-who in the draft. Her sophomore season is everything she could have asked for.
Then they play the new expansion team in Denver, and who else but four-foot-nothing Harrowhark Nonagesimus lays the highlight reel hit of the year on her at the blue line.
Gideon wants payback, and soon.

we'll embrace that much longer (make more of a mess) by SmallishWormMasterOfTheUniverse

Summary
Tim feels a bit of schadenfreude at the whole thing. He’d feel a lot more schadenfreude if he wasn’t the unlucky bastard on the other end of the chain. Why hadn’t he just gone home? Then the cuffs could’ve snapped shut on both of Jon’s wrists, and Tim would have returned to find him tied up and penitent and thoroughly incapable of skulking around like a creep until Tim damn well felt like letting him out.
After a scuffle over a mysterious package in the Archives, Jon and Tim end up locked together in a pair of handcuffs that don’t seem interested in letting them out. Surely this will end well.

Summary
“Harrowhark,” says Father Gaius, rolling the sounds around his mouth with the air of an unintentionally patronizing uncle. “That’s quite a…vivid name.”
“It reflects my late parents’ wish for me to free their community from the hell of Earthly temptation before the new millennium,” she explains in a deadened tone. If the pastor correctly hears free as a euphemism for lead in mass suicide, he gives no indication. “They believed my birth was prophesied.”
“Now, that would have been an interesting tidbit to list in your qualifications.” He grins, brandishing her resumé; when the joke falls utterly flat, his grin falters into something more pathetic. “The charismatics do tend to get carried away, don’t they.”
In the year 2000, Harrow gets a job at John Gaius's church, meets his handsome and pious daughter, and things go to Hell in a handbasket.
