Summary
After returning from Canaan House, having refused the promise of Lyctorhood, Harrowhark Nonagesimus tries to make sense of an uncertain future and a Ninth House without Gideon Nav. Gideon joins the Cohort, and learns that sometimes getting everything you always wanted isn't always everything it's cracked up to be. Both try to clumsily navigate what a relationship is supposed to look like after years of mutual hatred, followed by trauma bonding and one single honest conversation about big feelings. They do it all through trading letters, and are totally normal about it. Palamedes Sextus is a good, long-suffering friend.

Summary
"You are being," Silas says severely, "completely and utterly ridiculous."
"Am not," Colum replies, tone completely devoid of amusement. "It's a real and serious condition."
"It is not."
"It is. And you would see your nephew die of it rather than administer remedy."
Colum falls victim to a rare illness. Silas is not pleased about being made late to mass.

Summary
The Eighth House only very rarely procured wine for its supplicants and visitors, for one very simple reason: drunkenness was said to lead to fornication primarily, and occasionally other sins as well. Imbibing alcohol was only permitted in small quantities, and Templars from the Eighth were thoroughly instructed as to what the consequences for overindulging themselves were. Silas had, in fact, only had a sip or two of wine before coming to Canaan House while meeting with important representatives of the other Houses and the messenger who brought the summons from the King Undying himself. Even the first time, when Lady Pent and her husband had used the thinly-veiled excuse of their passing anniversary (as uncomfortable as that entire union made him), Silas had refrained from anything more than half a glass.
(Or, Silas gets drunk for the first time. He has the time ever.)

Summary
"Oh, you’re an absolute embarrassment,” Harrow whispers, looking down at Corona with no sign of hunger or desire or attraction. Only clinical curiosity. “I can’t believe you like this.”
“Stop it,” Corona gasps out, even as she doesn’t mean it. “Please. I’ll go, I promise."
“Well it’s too late for that now,” Harrow says. “You’re vastly underestimating how little power you have here.”

Summary
Gideon was having a perfectly normal, perfectly pleasant evening (or at least, what passed for normal and pleasant in Canaan House) when Harrow looked up from her flimsy-strewn desk and said,
"In the interest of remaining transparent, you ought to know that I've asked Sextus to marry me."
OR
Harrow and Palamedes refuse Lyctorhood, and get married instead. Gideon and Camilla are totally fine about it, honest.
God, however, is not.

Summary
Harrow had never wanted to believe that God was trying to kill them. For all the long, lonely years of her childhood, it was service to Him and to The Tomb that had kept her alive; it would have been sacrilege to end her own life when her life was dedicated to Him (and when it had been bought for so high a price). It had been inconceivable to her, when first presented with the idea, that the Kindly Prince, the King Undying, would ever order the annihilation of his own subjects, the heirs to his Houses.
However, at this point there was no arguing with the evidence.

Summary
Therapy had been the Fifth’s idea. Apparently the effort of dicking around with locked doors all day was putting too much pressure on them, and Abigail was a “licensed therapist”, whatever the hell that meant. Gideon still hadn’t figured that one out yet. Could have been normal on other houses (like salads, or having an “afternoon”) and the bony old assholes back home on the Ninth just hadn’t bothered.
Or, when Gideon Nav goes to group therapy, she learns new things about Harrow, Silas, and herself.

Have some life-affirming "virgins independently inventing light BDSM" courtesy 3 separate kinkmeme prompts: bone bondage, nipple torture, and Harrow wanting to touch Gideon but not being comfortable involving her own body in it. Bonus cuddling!
Her own breath is coming hard, too; this does feel just like fighting Gideon, or like having already won. She pops out a third pair of bone arms, at waist level, which come up to cradle Gideon's ribs. -
