The garden had a wall on its east side, old brick gone soft and green with moss, and it was over that wall that the cold was coming from — Thomas felt it before he saw anything, the specific drop in temperature that Niall's earth magic never produced and Carlyle's water never produced either, a cold that had a direction to it, that was reaching rather than simply existing.
KaSandra was already moving.
She did not stand so much as she arrived somewhere else, the bench empty where she had been a half-second before, her long coat — she had not been wearing it, Thomas registered dimly, and then she was, the dark fabric settling around her like something that had been waiting for permission — already between Thomas and the wall.
"Show yourself," she said. Not loudly. She never needed to say things loudly for them to carry.
For a moment nothing answered her.
Then the top of the wall was simply occupied, the way a shadow occupies a space without anyone seeing it arrive — a figure crouched on the moss-softened brick, and Thomas's first thought, absurd and immediate, was how quiet the figure was. No fabric sound. No breath he could hear. A person-shaped absence of the ordinary noises a body made.
She dropped down into the garden.
She was small — smaller than Thomas expected from the cold she'd brought with her, a compact economical build under a coat the color of old rust, the kind of coat that had been designed for someone to disappear inside of rather than to be noticed in. Her hair was cropped close and silver-white, not with age — her face was young, younger than Katherine's, sharp-boned and entirely without expression — but with something else, something that had bleached the color out of it the way frost bleaches color out of grass. Her eyes were the palest blue Thomas had ever seen on a person, so pale they were nearly colorless, and they moved across the garden once, cataloguing it, before settling on Thomas with the specific unhurried attention of someone who had already decided the outcome and was simply confirming the details.
"You're later than I expected," KaSandra said. "I thought you'd come before the ring."
"I like an audience," the woman said. Her voice matched the cold — flat, precise, without inflection that Thomas could read as anything human. "It's more honest. Everyone shows you who they really are in the half-second before they understand what's happening."
"You're the one who took the families," KaSandra said.
It was not a question. Thomas heard something underneath KaSandra's voice that he had heard only once before, the night she'd said Sebastian's name to a room full of people and held the grief to the size she believed he would have wanted — something contained with tremendous effort, a door held shut by hand.
"I'm the one who was sent to take the families," the woman said. "There's a difference. I only do the sending's math. Eleven names, eleven debts, eleven closings. Tierney Duke's people. Katherine Vaughn's people. Carlyle's mother." A small, terrible pause, weighted like she was tasting the words. "Yours, if your grandmother hadn't been faster than I was."
KaSandra's hand moved.
Thomas felt the temperature in the garden change again — not the assassin's cold now, something else, something that came off KaSandra in a wave he had felt only in fragments before, in training, when she demonstrated something and stopped herself short of finishing it because finishing it was not a training exercise.
"You have one thing left on your list," the woman said, and her pale eyes flicked to Thomas, and Thomas understood, in the half-second she had promised was honest, that the something else on the list had never been KaSandra at all.
She was fast.
Thomas had trained fast people. He had built formations around fast people, had drilled Kristen's blink-light against exactly this kind of speed, had run the math on reaction windows a hundred times in the basement with a stopwatch and a whiteboard. None of the math accounted for what he saw — the woman crossing the six feet of grass between the wall and the bench in a movement that did not look like running so much as the garden simply rearranging itself around her, a blade the length of a finger already free of her sleeve, dark-bladed, wet with something that caught no light at all.
KaSandra's power hit her a half-second too late.
It was not a clean hit — Thomas understood that even in the moment, some cold analytical part of him still running the observation even as the rest of him was screaming at a register that had no words in it. The woman had planned for KaSandra's speed. She had built her approach around losing an arm, or a hand, or whatever KaSandra's power took from her, because the trade she was making did not require her to walk away intact. It only required her to close the distance once.
The blade found the side of Thomas's neck.
It was not a deep cut. He knew, distantly, that it was not a deep cut — a shallow line, barely more than a scratch, the kind of wound that in any other circumstance would not have registered as an emergency at all. He felt the cold of it before he felt the pain, a specific cold that had nothing to do with the assassin's magic and everything to do with what was on the blade, spreading from the cut in a line down his throat and into his chest with a speed that had no business belonging to something that small.
He went down onto one knee in the grass.
"Thomas."
KaSandra's voice had lost every trace of composure it had ever had.
What happened next, Thomas would only ever have in pieces — the specific mercy and horror of a body shutting down its higher functions to survive something, leaving him fragments instead of a memory. He remembered the assassin's arm gone, taken clean at the shoulder by something he couldn't see the shape of, gone the way a candle flame is gone, simply absent where it had been present. He remembered the woman not screaming — some detached part of him registered that as strange, that she made no sound at all, even then — and he remembered KaSandra's face above him, the composed and careful thing gone completely now, replaced by something Thomas had never seen on her and hoped never to see again, something that belonged less to a person than to whatever the word for grief becomes when grief runs out of ordinary places to go.
He remembered the sound the assassin made when KaSandra finished it.
It was not fast, the finishing. Thomas understood that even through the cold spreading down his arms now, even through the grass going soft and strange beneath his other knee. KaSandra did not kill the way she trained the chosen ones to kill — efficient, economical, the fastest path to the safest outcome. She unmade the woman the way the cold had been unmaking Thomas, slow and total, the power that Thomas had felt only in fragments during training finally allowed to finish what it had always been capable of, and the garden that had held a proposal ten minutes before held something else entirely by the time it was done, something that the old dead tree looked down on with the same indifference it looked down on everything.
KaSandra was beside him before the sound had finished.
"Look at me," she said. Her hands were on his face, and they were shaking, and Thomas understood distantly that he had never once, in two years, seen KaSandra's hands shake. "Thomas. Look at me."
He tried.
The garden had gone strange at the edges, the gold light bending in ways gold light did not bend, and somewhere behind KaSandra he could hear the house erupting — Tierney's voice, sharp and afraid, and under it Dean's, and under that the sound of the basement door slamming open, feet on the stairs, the specific chaos of a house that had felt something wrong through its walls the way houses full of people who loved each other always did.
"It's not the ritual poison," KaSandra said, and Thomas understood she was talking to herself more than to him, running through possibilities the way Thomas ran through formations, "it's not the same as the vial, it's cut differently, it's meant to—" She stopped herself. Her hands tightened on either side of his face. "It's meant to be slow. That's good. Slow I can work with. Slow means there's time."
"KaSandra." His voice did not sound like his voice.
"Don't talk."
"I have to say—"
"You already said it," KaSandra said, and there was something fierce underneath the fear now, something that Thomas recognized because he had built his entire life out of the same material. "You said it in the garden ten minutes ago and I said yes and that is the last thing either of us needs to say today. Do you understand me? That's finished. That's done. Everything else is logistics, and I am very good at logistics, and I am not losing you to logistics."
The others were in the garden now — Thomas registered them as shapes more than people, Katherine's voice sharp with something he'd never heard from her, Niall already on his knees beside the wall, feeling for something in the ground with both hands flat against it. Carlyle's water was already moving toward him, cool and searching, trying to find the poison's edges the way Carlyle found the edges of everything.
"Coven of light," Niall said, not looking up. "It has to be the coven. Nothing here touches this."
KaSandra's jaw tightened.
"I know," she said.
"KaSandra, that's—"
"I know what it is," she said, and there was something final in it, the sound of a decision already made, weighed, and accepted before anyone else in the garden had finished forming the question. She looked down at Thomas, at the cold spreading through him, at the ring still half onto her finger catching what was left of the light.
"Hold on," she told him. "You don't get to be careful about this one thing and then die being careless about it. Hold on."
Thomas held on to the only thing he had left to hold on to, which was her voice, and the world went dark around the edges of it, narrowing to that single point, the way the whole eleven days had narrowed to a single moment in a garden that no longer looked like the garden he remembered.
~
Later — Katherine would not be able to say how much later, because time in the garden that evening had stopped behaving like time — she would remember the specific quality of the silence that fell once Carlyle's water pulled back from Thomas's throat with nothing more it could do.
"It's not touching it," Carlyle said. His voice had none of its usual steadiness. "Whatever's in him, it doesn't read as poison. It reads like it's not supposed to be found."
"Because it isn't supposed to be found," KaSandra said. She had not moved from her knees in the grass. "That's the design of it. It's built to survive being looked for."
Niall was still on the ground near the wall, both hands flat against the soil, his face turned inward the way it went when he was reading something through the earth that no one else in the garden could read. "There's more of them," he said. "Not here. Somewhere else. I can feel the shape of where she came from and it isn't a shape one person makes alone."
"Later," KaSandra said. "That's a later problem."
Tierney had reached the edge of the garden with Dean half a step behind her, favoring the arm he'd insisted was fine, and Thomas heard — from somewhere very far away, from the narrowing dark at the center of himself — Tierney's voice break on Katherine's name, a mother's specific fear translated instantly into checking her own child was whole before it allowed itself to register anything else.
"He's not going to die in this garden," KaSandra said. She said it the way she said most things that needed to be true — flatly, without room in it for anyone to argue, including herself. "I won't allow it. Do you understand me. I have spent three weeks learning what this house can survive and I am not adding this to the list."
"KaSandra." Katherine's voice, close now, kneeling on Thomas's other side. "The coven — you haven't been back since—"
"I know exactly how long it's been since I've been back," KaSandra said, and something in her voice made even Katherine go quiet. "I know what it will cost to walk back through that door and I am going to pay it, because the alternative is watching him die in the grass, and I have already watched enough people die in gardens and hallways and basements to last several lifetimes, and I refuse — " her voice caught, the first crack Thomas had heard in it since she'd said the word don't move an eternity ago, "—I refuse to add his name to that list today."
She looked down at him.
Thomas's eyes had gone half-closed, his breathing shallow and uneven, the cold that had started as a line at his throat now sitting somewhere behind his ribs, patient and total the way the assassin herself had been patient and total, as though the poison had learned its manner from the woman who carried it.
KaSandra gathered him against her, careful of the wound, careful of everything, and stood with a strength that should not have belonged to someone her size, the long dark coat settling around both of them.
"William," she said, not loudly, but the name carried across the garden the way her voice always carried when it needed to. "I need a door. Not a normal one. I need the one that goes to the mountains, and I need it in the next five minutes, or I need you to tell me honestly that it can't be done, so I can start finding another way."
William was already moving before she finished the sentence, and the last thing Thomas heard clearly, before the dark at the center of himself closed the rest of the way over, was the particular sound of the air folding itself open at William's hands — the sound, he would think much later, of a door being built out of nothing but urgency and love, which was, he supposed, as good a material as any to build a door out of.
