The invitation arrived on actual vellum.
Ro held it up to the diner's fluorescent light, turning it between two fingers. The paper was too thick. The ink was too dark, the kind of dark that didn't come from any printer she'd ever seen. It smelled faintly of woodsmoke and something older — petrichor, maybe, or the inside of a church that hadn't been opened in a century.
"You are holding that like it might bite you," Caelan said, from the booth by the window.
"Everything in your world bites." She set it down on the counter. "What's the Twelfth Assembly?"
He was quiet for a long moment. Long enough that she looked up from the invitation.
Caelan had that look again — the one she'd started cataloguing in her head. Like he was doing rapid calculations behind those amber eyes. Like he was deciding how much to give her and how much to keep.
"It is a gathering," he said finally. "Of the high courts. Held every twelve years, in the Between."
"The Between." She'd been learning the vocabulary. The Between was the space that wasn't quite the fae realm and wasn't quite London. The layer of city underneath the city. "And you're presenting."
"I am required to present. On the cult threat." A pause. "On the anchor situation."
The anchor situation. Her. She was the anchor situation.
"Then I'm coming."
He didn't argue immediately. That was new. He picked up his coffee — she'd made it wrong again, two sugars instead of one, and he'd said nothing, just drank it anyway — and looked at it with the focused attention of a man choosing his next words very carefully.
"The Assembly does not admit humans."
"The Assembly hasn't had a human anchor before."
"That is precisely the problem."
Ro leaned on the counter. The diner was empty tonight, properly empty — Denise had gone home early with a headache, and the last customer had cleared out around two. Three in the morning, and London was doing that thing it did, where the streets went strange and quiet and the sky turned the particular sodium orange that made everything look like a memory.
"Caelan." She waited until he met her eyes. "If you stand up in front of your whole political circus and explain what I am without me there, you're giving them a story about me. You're letting them define it. That's bad strategy."
Something shifted in his expression. He hadn't expected that particular angle.
"You have been thinking about this."
"I think about a lot of things at three in the morning. It's a side effect of working the night shift." She picked up the invitation again. "Who sent this?"
"Lady Maren. She is... convening this particular session. She leads the Winter Court's political faction. She is not my ally."
"She sent you an invitation with your name on it. And mine."
She watched that land. Watched him look at the invitation properly — and yes, there it was, her name alongside his in that dark ink. Rowan Blackwood. Spelled correctly, which was somehow more unsettling than a misspelling would have been.
"She knows about me," Ro said.
"She has known for some time."
"You told me the anchor connection was subtle. That most fae would not—"
"I said most would not notice immediately." He set down his coffee. "Lady Maren is not most fae. She has been gathering information on me since the cult first appeared. Since the first anchor was killed." He paused. "She is politically motivated. If she can demonstrate that my connection to a human has made me vulnerable — or that I have been irresponsible — she can push me out of the Autumn Court's standing at the Assembly."
Ro was quiet, processing.
"So she wants me there to embarrass you."
"Or to interrogate you. Or to expose you as a liability." His voice was level, clinical almost — but his hands, resting on the table, were too still. "She does not intend your invitation as a courtesy."
"Great." Ro folded the invitation with the kind of care you give to a potential weapon. "Then we go in with a plan."
"Rowan—"
"Don't 'Rowan' me. You need to present on the cult. I am the single most relevant data point you have — I survived an anchor killing that should have worked, and I'm still functional, which nobody can explain. Right?" She watched his jaw tighten. "Right. So I walk in there as evidence, not as a liability. I walk in as proof that the Autumn Court did something right."
"That is not how fae politics—"
"I know it's not how fae politics work. I'm suggesting we do it differently." She pulled out a notepad — actual paper, she'd started keeping one for exactly this kind of conversation. "Show me the structure. The Assembly. Who's there, what the hierarchy is. Give me the political map."
He looked at her for a long moment.
She'd gotten better at reading those looks. This one was the one she privately called the *Vermeer* — like he was trying to figure out where the light was coming from.
"This is inadvisable," he said.
"Noted. Tell me anyway."
---
He told her. It took an hour and most of a pot of coffee.
The Twelfth Assembly: seven courts, their representatives, their particular grievances. The Autumn Court — Caelan's court — held a midrange position politically. Old bloodline, significant territory in the Between, currently under pressure because of the cult activity and what it implied about Autumn Court security.
Lady Maren of the Winter Court had been building a case for six months. Caelan had known. He had been preparing his own presentation.
He had not planned to bring Ro.
She could see that, watching him lay it out. This was his world — precise, dangerous, stratified in ways that made the Tate Modern's board politics look like a playground dispute. He'd been navigating it for three hundred years. He knew exactly what he was doing.
But he'd been planning to navigate it alone.
"You were going to present me as a theoretical," she said.
He didn't deny it. "I was going to present the anchor connection as—"
"As something that happened to you. Not someone." She tapped her pen on the notepad. "That's your mistake. Lady Maren gets to show up to this Assembly with the real thing and you get to show up with a dossier. Who wins that?"
Silence.
"She sent me the invitation on purpose," Ro continued. "She wants me in the room. Which means she's already figured out I'm a problem for you. The only way to make that not a problem is to make me an asset." She looked at him steadily. "I need to be prepared. Tell me the protocols."
"You do not understand what you are asking."
"Explain it until I do."
Outside, a night bus rolled past. London being London. Somewhere in the sky above them — in the layer of city that wasn't city — something old and political was waiting.
Caelan looked at her face for a long moment. Whatever he was calculating, she watched him reach the end of the equation.
"The Assembly convenes in four days," he said. "We will need to work."
"I have four days off starting Thursday."
A pause. "That is convenient."
"I scheduled it when you mentioned the Assembly two weeks ago."
He stared at her. She picked up her pen and flipped to a clean page.
"Start with Lady Maren," she said. "What does she actually want?"
His expression — the one that wasn't quite surprise but was adjacent to it — settled into something she didn't have a name for yet. Something careful and intent and warm in a way he'd never acknowledge if she pointed it out.
"She wants the Autumn Court diminished," he said. "She has wanted that for forty years."
"Okay." She wrote it down. "What's she afraid of?"
He blinked. Stopped.
"You are asking what she fears."
"Everyone's afraid of something. It's the most useful thing to know about a person." Ro looked up. "What is Lady Maren of the Winter Court actually afraid of?"
Caelan was quiet for a long moment.
"Irrelevance," he said at last. "She has held power by being the most informed person in any room. For the past six months, she has been outpaced by events she did not predict." He paused. "She did not see the cult coming. She did not predict the anchor killings. She has been reactive rather than ahead, and it has cost her."
"So she's rebuilding credibility. Using us." Ro nodded slowly. "Then we need to make sure showing up to this Assembly costs her more than it gains her."
She kept writing. Caelan watched her.
"You are surprisingly good at this," he said.
"I spent three years in art history academia. It's just backstabbing with footnotes." She didn't look up. "Tell me about the rest of the courts. Who might be persuadable?"
---
They were still talking at dawn, when the city started coming back to itself. When the light through the diner windows shifted from orange to grey to the particular thin gold of early morning.
Ro had four pages of notes. Her hand hurt. She'd drunk too much coffee and not enough water, and she was aware, in the way you're aware of something when you've been trying not to notice it, that Caelan had been watching her differently as the night went on.
Not the *Vermeer* look. Something else.
She didn't name it.
"You should sleep," he said.
"So should you. Do you sleep?"
"When I choose to."
"That sounds exhausting." She capped her pen. "Four days. We have a plan and a half."
"We have an outline and considerable risk."
"Same thing." She started stacking the notepad. "Caelan."
"Yes."
"If Lady Maren tries to use me against you in there — if things go sideways—" She stopped. Chose her words. "I need you to trust that I can handle it. I know you're used to doing this alone. But you're not alone in this one."
He was very still.
"I am aware," he said finally.
She wasn't sure what that meant, exactly. But the way he said it — like the words cost him something — stayed with her longer than she expected, walking home through the London morning, her notes tucked under her arm, her mind already working through angles.
Four days.
She was going into the Assembly.
And she was going to make sure the Autumn Court walked out with its footing intact.
What she didn't think about — deliberately, carefully didn't think about — was the way he'd watched her at the end. Like she was something he didn't have a category for.
Three hundred years, and she'd apparently found the gap in his filing system.
She told herself that was purely satisfying from a strategic standpoint.
She mostly believed it.
