AI The oak trees beyond the deer path were wrong.
Rory stopped where the grass gave out and stared. She had run deliveries all over London in the rain and the dark, had cut through Richmond Park a dozen times with a backpack full of someone else's dinner going cold, and she knew what English oaks looked like in late November . Bare. Patient. A little bleak.
These had leaves.
Not a few stubborn brown scraps clinging to the branches, but a full, impossible canopy, green shot through with gold , and beneath it a drift of wildflowers so thick the ground seemed to move when the wind touched it. Bluebells in November. Poppies. White flowers she had no name for, opening and closing in slow rhythm, as if they were breathing in their sleep.
"Tell me you're seeing that," she said.
Nyx stood beside her, or near enough to count as standing. At a little over six feet in solid form they cut a thin, humanoid silhouette against the grey park, but the edges of them never quite settled, darkness feathering off their shoulders the way heat lifts from tarmac. Their violet eyes glowed faintly in the murk.
"I see it," they said, in that voice like a whisper carried across a field. "I would prefer that I did not."
"Brilliant. That's reassuring."
"It was not intended to be."
Ahead of them, half lost in mist, stood the stones. Seven of them, if you counted the one that had fallen and lay sunk to its middle in moss. They were not tall, not like the postcards of Stonehenge Rory's mother had stuck to the fridge when she was a girl, but they were old in a way that made her teeth ache to look at them. Ancient oaks grew between and through them, roots buckling over grey rock, trunks twisted together as though the trees and the stones had been arguing for centuries about which of them had arrived first.
Rory pulled out her phone. No signal. That was not unusual out here, but the clock was wrong. It read 16:04, then 16:03, then 16:04 again, the numbers flickering each time she blinked at them.
"Nyx."
"I know."
"You know about the clock, or you know in general, because those are very different levels of comforting right now."
"Time does not sit straight in such places." They drifted forward, feet making no sound in the wet leaves, and where their shadow fell across the fallen stone it pooled too deep, too dark for the thin afternoon light. "It pools. It slips. An hour in her grove may be minutes beyond it, or days. Do not trust anything here that measures."
Rory tucked the phone away and felt, stupidly, a little bereft without the lie of it. Her thumb found the small crescent-shaped scar on her left wrist and worried at it, an old habit. The Heartstone pendant hung cold at her throat on its silver chain, the crimson stone, no bigger than her thumbnail, dull against her skin. It had been warm this morning, almost alive , when she passed that boarded-up arch near the river. Now it lay inert. Whatever this place was, it was not Hel, and the pendant knew the difference even if she did not.
"So what do we do?" she asked. "Knock?"
"We cross, and we are polite, and we do not eat, drink, accept a gift without counting its cost, or give her our true names in full."
"You used my name to get us here."
"I used the path," Nyx said. "That is different. She will know you regardless."
Of course she would. Three hundred years old, Isolde had time to learn the names of most things. Rory swallowed a laugh that was not entirely humour and stepped over the line of stones.
The air changed on her skin before her mind caught up. It was not a door, exactly. There was no click, no fall. It was the feeling of wading from shadow into sun-warmed water, a faint shimmering distortion that bent round the edges of her vision and slid, cool and resisting, over her face, her hands, the back of her neck. For one vertiginous instant she heard Richmond Park twice, the distant traffic and a dog barking somewhere toward the road, and under it something else, something vast and slow, like a chord struck on a string too large to see. Her ears popped. The barking dog was gone .
The cold went out of the world.
It was warm inside the grove, a deep, green warmth that smelled of crushed leaves and honey and rain that had not fallen. The light had changed too. It fell through the canopy in long amber shafts, though the sun outside had been a watery smear behind cloud, and motes of gold hung in it, drifting not down but sideways, curling in patterns that made her eyes follow them against her will. When she looked up, the branches met so far above her that the leaves belonged to another season and perhaps another sky. Trunks wider than a bus rose into that green distance, bark silvered and scarred with shapes that might have been carvings, might have been faces worn smooth by time. If she did not look at them directly, they seemed to turn, very slightly , to watch her pass.
"Don't touch the trees," Nyx murmured.
"I wasn't going to."
"You were reaching."
She was. Her hand had lifted of its own accord toward a knot in the nearest trunk that gleamed wetly, like an eye half open. She shoved both hands into her jacket pockets and kept walking.
The path, if it was a path, was only a place where the wildflowers grew a fraction thinner. They brushed at her ankles through her jeans, leaving pollen on the denim that glittered. Every colour here was too much. The bluebells were not blue so much as the memory of blue at dusk, the poppies a red that hummed at the back of her eyes. Small insects, or things shaped like insects, stitched light between the stems. One landed on her sleeve and she froze. It had too many wings, all of them translucent as soap bubbles, and a body like a drop of amber with something dark curled inside it. It tasted the cuff of her jacket with a tongue like a thread of silk , considered her, and lifted away in complete silence .
"Was that—"
"Not dangerous," Nyx said.
"Right. And you'd tell me if it was?"
"I would tell you after, if there were time to learn from it."
"You're a terrible guide."
"I am an excellent guide. I am a terrible comfort."
That startled a real laugh out of her, and the grove answered it. All around them, very softly , the flowers chimed. It was not a sound she heard with her ears so much as one she felt in the fillings of her teeth and the small bones of her wrists, a clear, high ringing that rose and fell with her breath. The gold motes in the light turned toward her, curious. The hair stood up along her arms.
"Stop laughing," Nyx said, gently , which was worse than any warning.
She pressed her lips together. The chiming faded, reluctant. In the quiet that followed she became aware of other sounds, layered under the hush. Water running somewhere to her left where no stream showed itself. A slow, regular creaking, like a ship at anchor, from the great trees. And beneath everything, just at the threshold, voices. Not words. The shape of words, conversational, unhurried, as if a crowd were talking in the next room of a house whose walls were made of leaves.
She kept her voice low. "Is that them? The Courts?"
"No. This is only the edge of what was left behind when they withdrew. An echo in a shell." Nyx had gone more solid as they walked deeper, the violet of their eyes deepening. She had learned that meant they were uneasy, though they would sooner dissolve entirely than admit it. "Isolde lives in a pocket, Rory. Between Earth and what lies on the far side of the Veil. Pockets collect things."
"What kind of things?"
"Lost things. Old things. Things that fell through the cracks between one realm and another and could not find the seam again."
As if the grove had been waiting for her to understand, the trees opened ahead.
The clearing was perfectly round, and perfectly still. A pool occupied its centre, black and smooth as polished glass, ringed with stones worn into soft, seated shapes. No leaf floated on it. No ripple broke it, though Rory could feel a breeze moving in the flowers at its edge. It reflected the canopy and the strange gold light and Nyx, a violet-eyed smudge of night standing in defiance of the afternoon, and when Rory stepped close enough to see herself, her reflection looked back at her a heartbeat too late.
She recoiled. Her reflection smiled after she had stopped.
"Don't look long," said a voice behind them, "unless you wish to be looked back at."
Rory turned so fast she felt her shoulder-length hair whip against her cheek.
The woman stood among the wildflowers on the far side of the pool, and Rory could not have said whether she had been there a moment before. She was smaller than Rory, five foot five perhaps, and slight in the way a reed is slight, because it bends instead of breaking. Her silver hair fell unbound to her waist and moved though the air around her was still. Her face had no age in it at all, and her eyes were a pale, unsettling lavender, clear as spring water over stone. She wore something long and grey-green that might have been a dress centuries ago and had since decided to become part of the landscape. When she crossed toward them she left no footprints in the soft, damp earth. The flowers did not bend where she passed. They leaned toward her.
"Aurora Carter," Isolde said, and smiled as if she had tasted the name and found it interesting. "And the Nightwhisper, who was Aldric once, before the spaces between took his shape from him. You are a long way from the shadows you keep, Shadow."
Nyx inclined their head, a fraction. "Seer."
"I did not invite you," Isolde said, pleasantly .
"No," Rory said. "You did, actually. Indirectly. Through three dreams, a magpie that kept leaving buttons on my windowsill, and a vision Nyx said would get worse if I ignored it. So. Here we are, ignoring it in person."
The lavender eyes settled on her and Rory had the sudden, crawling conviction that Isolde could see not merely her face, her bright blue eyes gone wide, but the whole untidy line of her twenty-five years laid out behind her like footprints in snow. Cardiff. Her father's careful voice. Her mother. Evan, whose name she still flinched from in the dark. London rain on the flat above the bar. Eva's hand pulling her onto a train. All of it, read at a glance, and weighed, and found neither wanting nor sufficient. Just known.
"You seek what hunted you to the river arch," Isolde said. "You seek why the warm stone wakes, and what slipped its leash when the Veil grew thin."
"I seek a straight answer," Rory said.
At that, Isolde laughed, and it was a lovely, terrible sound, like the chiming of the flowers only given intent. "Then you have walked into the wrong wood, daughter of the barrister. Straight answers die young here. They cannot bear the air."
"Can you lie?" Rory asked.
"No." The word was simple, and absolute, and somehow sad. "The Courts took much from me when they cast me out for telling mortals what I saw. They did not take that. I cannot lie to you, Aurora. I can only choose which truth to set upon the path, and watch to see whether you step on it." She lifted a hand and gestured, not at the pool, but at the trees, at the grove entire, as though it were a room she kept. "You have questions. I have seen the asking of them, on water, on glass, in the hollow of a dead king's hand. Ask one. Only one, this first time. The grove dislikes greed in its guests."
Rory glanced at Nyx. Their face was a silhouette without expression, but their shadow, cast long across the wildflowers, had reached out without their body moving, and curled, protective and unmistakable, around her ankles.
She thought of the Heartstone warming at her throat beside a bricked-up arch that should not have breathed cold air in summer. She thought of the thing she had not seen, only felt, that morning , a pressure against the world like a thumb against a bruise.
"When the winter solstice comes," she said carefully , "and the Veil gets weak. What comes through the arch under the river?"
Isolde went very still. The gold motes stopped their drifting. Even the slow creak of the trees seemed to hold.
"Not what," she said at last. "Who. And not through, child. Not yet. It stands on the far side with its face to the thinning glass, and it learns the shape of your name the way frost learns a window." She came closer, silent over the earth, and Rory saw that her eyes were not lavender at all when near, but filled with a moving light, as if something were swimming far down in them. "It will not be first through, either. The little hunger comes before the great one. Teeth before the mouth. You will know it by the smell of a feast in a place where no one is eating. You will know it because your cold stone will burn."
"Dymas," Nyx whispered, and for once the whisper held no wind in it at all. It held dread.
Isolde inclined her head. "The amber place. Prince Belphegor's orchard, where nothing is ever refused and everything is owed." Her gaze returned to Rory. "You will go there. I have seen you at the long table, refusing the cup, and I have seen you in the vineyard with black earth under your nails. Which of those women survives, I have not seen. That seeing is withheld from me, and things withheld from me are rare enough to frighten me on your behalf."
Rory's mouth had gone dry. "That's— You call that an answer?"
"I call it the truth," Isolde said, "which you mistook, as mortals do, for the same thing." She reached into the folds of her strange, rooted dress and drew out a dagger.
The grove changed around the drawing of it. The light thinned to something silver, though no moon hung above the canopy, and along the blade's leaf-shaped edge a faint luminescence woke, pale and clean. It was moonsilver, slender as a willow leaf, and Rory could feel the cold coming off it from three feet away, a winter that had never heard of spring. Isolde held it across both palms, offering it the way one offers something holy or something dangerous, which in Rory's recent experience amounted to much the same.
"This was forged in the Courts before your city's first stone," Isolde said. "It cuts wards. It cuts what wears flesh it did not earn. Against the children of Hel it bites deepest of all. Take it."
Nyx's shadow tightened round Rory's ankles. "Isolde. We counted costs on the path here."
"And this cost is mine to carry, Shadow, not hers. It is a gift." The lavender eyes never left Rory's face. "Do you understand me, Aurora Carter? A gift, freely given, with no debt laid upon it by me. What the blade itself asks of the hand that holds it, I cannot answer for. Such things are hungry in their own way. Will you take it still?"
Rory looked at the dagger. She thought of the arch, and the cold, and the pressure of a face against thinning glass. She thought of being twenty-five and part-time and ordinary, except for all the ways she apparently no longer was. Her hand, when she reached out, did not shake, and she was fiercely proud of that, and suspected Isolde saw the pride and the fear beneath it both.
The hilt was cold enough to sting. The cold travelled up her fingers, into the crescent scar on her wrist, and settled there like remembered pain, and then, strangely, like steadiness. The blade hummed, very faintly, in a note she felt rather than heard, and in the black pool at her side her reflection, her true one, her timely one, closed its hand around empty air in perfect unison with her own.
"I'll take it," she said.
Isolde released the dagger and stepped back among the flowers, leaving no mark of where she had stood, and beyond the clearing the great trees of the grove resumed their slow, ship-like creaking, and the hidden water ran on toward no stream, and the voices beyond the leaf wall took up their patient conversation again, as if a door somewhere very far away had just been quietly, irrevocably, unlocked.
