AI The oaks at the edge of Richmond Park were not where Rory had left them.
She stopped on the wet grass and checked the path behind her. The deer had vanished, though she had heard them moving through the bracken a minute before. The last of the London light hung low and iron-grey beyond the trees, and her breath smoked in the cold. December had stripped the branches bare. It should have smelled of rain and rotting leaves.
Instead, a thread of sweetness curled through the air, too faint to name. Honey. Warm earth. Something green and crushed.
"You see it too," she said.
Nyx stood beside her without quite standing on the ground. In the failing light they were taller than they had been on the street, six feet and more of shadow gathered into a human shape, their edges eating what little colour remained. Only their eyes burned clear, a faint violet glow where a face should have been.
"I see a door pretending not to be one," Nyx whispered. The wind carried their voice from somewhere behind her left ear, though their mouth, if they had one, never moved. "Doors in this place rarely open both ways."
Between the oaks, seven standing stones leaned together in a ring too small for comfort. Rory had walked this part of the park before, with takeaway coffees and Eva complaining about her boots, and she would have sworn on her unfinished law degree there had been nothing here but mud and a fallen log. Now lichen veined the stones in spirals. Snow had begun to fall beyond the trees, thin white flecks that melted before they reached the ring.
Her phone said 4:47. She watched the minute hold, refuse to turn, then flicker back to 4:46.
"Time's wrong," she said.
"Time is polite here," Nyx said. "It waits to be invited."
That was not reassuring. Rory rubbed her thumb over the small crescent scar on her left wrist, an old habit she had never quite broken, and took out the Heartstone without deciding to. The crimson gem lay against her palm, thumbnail-small on its silver chain. For weeks it had carried its own treacherous warmth , pulsing whenever something from Hel pressed too close to the world. Now it was cool. Not dead. Listening.
Beyond the stones, the air shivered.
At first she thought it was heat-haze, impossible in the cold. Then the shimmer deepened, a distortion like breath on glass, and through it she saw colours that could not belong to a winter evening in Richmond. Gold pooled where there should have been shadow. Flowers lifted blue faces from grass that was suddenly , impossibly green.
Rory's heart kicked hard once.
"That is the Veil," Nyx said, and for the first time their whisper came from directly beside her, as if even they did not trust themselves to be overheard. "Thin enough to step through. Thin enough to tear."
"And Isolde is in there."
"Isolde is the reason the grove tolerates visitors. Do not mistake tolerance for welcome."
"Noted." Rory tucked the pendant back beneath her coat. Her bright blue eyes stayed on the shimmer. Cardiff common sense, her mother's voice, her father's courtroom logic — none of it had prepared a vocabulary for this. She made do. "We don't eat anything. We don't give our full names to anything that asks. We stay on the path."
"There may not be a path."
"Then we stay together."
Nyx's head inclined. Their shadow thinned at the shoulder and rewove itself. "A sound plan. The grove will enjoy dismantling it."
Rory stepped between the stones.
The cold did not fade; it was taken . One stride her boots squeaked on frost, the next they pressed into warm, springy turf that gave off the scent of rain after sun. Sound changed in her ears with a soft pop. Traffic, dogs, the distant complaint of a plane over Heathrow — gone. In their place came water running somewhere out of sight, and a layered birdsong so rich it took her a moment to understand no single bird was singing . Each note arrived a fraction after its echo , as if the grove were remembering the song rather than making it.
She turned. The stones stood behind her, but Richmond Park did not. Grey winter showed through the gap in a narrow, wavering slice, already distant, like a picture hung at the far end of a corridor. Snow fell through that slice and stopped mid-air at the threshold, melting into sparks.
"Oh," Rory said quietly. "That's —"
Words failed in a way she resented. Wonder rose through the fear, clean and embarrassing as childhood. Wildflowers crowded the clearing in defiance of season: bluebells beside foxgloves, primroses opening under roses, white blossom drifting from branches heavy with autumn fruit. Every bloom she named belonged to a different month. Together they made the air thick and dizzying. Above them, the canopy braided oak and silver birch and trees she could not identify, their leaves turning slowly though there was no wind, showing first green, then gold, then a translucent underside veined with light.
The light had no source. It lay amber over everything, not sunset and not morning, and in it Nyx kept losing definition. Their form guttered. One moment they were solid enough that grass bent beneath them; the next, Rory could see flowers through their chest.
Nyx noticed her looking. "The shadows here are not empty," they said. "They object to being worn."
"Can you stay?"
"For now." Their violet eyes narrowed . "Do not follow me if I come apart. A shadow separated from its shape may return wearing another."
Rory filed that under things she would absolutely worry about later. She crouched and pressed her palm to the ground. Warmth pulsed up through the soil, slow and regular. For one horrifying second she was certain the grove had a heartbeat, and that it had just noticed hers.
She stood too quickly . "There's a path."
"Now there is," Nyx said.
The flowers had drawn apart ahead of them, revealing a track of pale earth no wider than her shoulders. It had not been there when she looked a breath before. Or she had not been permitted to see it. The distinction felt important and unhelpful.
They followed it deeper.
The grove expanded as they walked. That was the only honest word for it. Trees Rory had taken for a boundary kept retreating beyond new clearings. A stream crossed the path, running uphill over black stones, its water so clear that the pebbles below seemed magnified and edged in silver . Tiny fish turned in it, and each fish cast two shadows, one following, one darting ahead as though it knew where the fish would choose to go.
Rory stopped on the narrow bridge of roots. "That's not possible."
"Here, possible is a local custom." Nyx glided over the water without using the bridge at all, and landed less solid than before. "You are thinking too loudly. The place hears appetite better than speech. Want carefully ."
She wanted, suddenly and sharply , to run back. She wanted Evan's voice to stop being the thing that had chased her from Cardiff. She wanted her mother to understand why law had felt like a room with no windows . She wanted answers about the pendant and Hel and why a delivery job at the Golden Empress had become the least strange part of her life.
The flowers along the bank leaned toward her, faces opening wider.
Rory took her foot off the bridge and set it firmly back on the path. "Nice try," she told the grove .
Somewhere among the trees, something laughed with wet leaves.
They went on. The deeper they travelled, the more her senses disagreed with one another. She heard the scent of rain before it darkened the leaves. The amber light tasted faintly of copper on the back of her tongue. When she brushed a fern, the frond recoiled, then curled affectionately around her wrist until she shook it free. Her skin prickled. The small hairs on her arms lifted, not from cold, but from the attention of the place . Every branch seemed to hold its pose only while observed. Out of the corner of her eye, trunks shifted. Looked at directly, they were innocent.
The path forked around a tree whose roots had grown over a stone chair. On the chair sat a bowl of black water. In the water, Rory saw the flat above Silas' bar, her own narrow bed, the window lit as she had left it that morning. Then the reflection rippled, though no breeze touched it, and she saw the same room at night with the door open and a man standing inside whom she would not, could not, look at long enough to name.
Her hand went to the Heartstone. It had warmed by a single degree.
"Don't," Nyx said.
Rory jerked back. She had been leaning toward the bowl without knowing she had moved.
"The grove offers mirrors to the lost." Nyx's whisper scraped thin. "It rarely returns the same face."
"I'm not lost," she said, and was annoyed by how much effort the sentence required.
"No," said a woman's voice from behind the tree. "You are merely not yet found."
Rory turned so fast the world dragged.
Isolde Varga stepped from between two trunks that had definitely been touching a moment ago. Silver hair fell to her waist, unbound, unsnarled by branch or bramble. Her pale lavender eyes held Rory with an ageless calm that offered no comfort at all. She was shorter than Rory, ethereal in a way that made the flowers seem coarse, and when she walked down the path her feet disturbed nothing. Rory looked, because she could not help it. Damp earth. Fallen petals. No footprints.
Nyx bowed. In their shadow, the gesture looked like a candle bowing in its own flame. "Seer."
"Nightwhisper." Isolde's gaze moved over them, and the light dimmed where it touched their shape. "You bring me a Carter, a stone, and a winter that has forgotten its manners. Two of the three are dangerous."
"You knew we were coming," Rory said.
"I knew a coming," Isolde replied. "You have chosen to be its shape." She tilted her head, listening to something Rory could not hear. "Ask, then. But know that a true answer and a kind one are seldom sisters."
"We need to know what the Heartstone is opening," Rory said. "And why it pulses near Hel. And whether Belphegor—"
The grove stilled.
It was worse than any sound. Birdsong cut off mid-note. The uphill stream froze in its bright arc. Even the leaves stopped turning. The name lay on the amber air like ash. Rory felt Nyx gather abruptly solid at her side, cold pressing through her coat where their arm almost touched hers.
Isolde was no longer smiling. "Speak princes softly in borrowed gardens, Aurora Carter. Some hungers are flattered to be remembered where feasts are grown."
"Dymas," Nyx murmured. "She means—"
"I mean what I have said," Isolde said, and because Rory knew the old stories she understood at once: the seer could not lie. Every evasion was a shape around a truth, not a departure from it. "Walk with me. The heart of the grove dislikes being approached by those who stand still."
There was no refusing, because the path had already closed behind them. Flowers stood shoulder-high where they had come through, woven tight with briar. Rory's phone buzzed once in her pocket. She took it out. No signal, no battery icon, only the time crawling in a circle: 4:47, 4:46, 4:47, 9:13, midnight. She put it away.
They followed Isolde between trees older than London. Bark peeled in her passing to reveal eyes of pale wood that closed as Rory passed. The stream returned, whispering now in syllables just below recognition. At one point she heard Eva laugh, clear and close, and had to bite the inside of her cheek to keep from answering. At another, the smell of her father's study — paper, leather, rain on Cardiff stone — rolled from a hollow oak so powerfully that her eyes stung. Nothing emerged from the hollow. That restraint felt worse than if something had.
The grove's centre opened without warning.
A circle of grass lay under a sky that had no business above Richmond. Stars burned there in daylight amber, constellations arranged in spirals Rory did not recognise. At the middle rose a tree so vast its lowest branches vanished into cloud, its trunk split around a hollow filled with moonlight, though there was no moon. Beneath it, a pool reflected the stars. Along its edge, wildflowers bloomed white, all of them, as if colour itself bowed here.
Isolde stopped at the pool. "Kneel," she said.
"Why?"
"Because the gift has waited longer than your line has borne your name, and gifts of the Courts grow teeth when kept waiting." Isolde reached into the hollow of the tree. Her hand went farther than the trunk should have allowed, past bark, past darkness, into that improbable moonlight. When it withdrew, she held a dagger.
It was slender and leaf-shaped, wrought of a metal that was not silver but remembered it — moonsilver, cool and luminous, glowing faintly now as if the pool lent it light. Isolde offered it hilt-first. Even from a foot away, Rory felt the cold coming off the blade.
"I can't take that," she said.
"You can," Isolde said. "That is the difficulty the visions enjoy."
"What is it for?"
"Cutting what pretends a door is a wall. Parting wards. Reminding demons that older bargains than theirs still keep their edges." Isolde's lavender eyes flicked once toward Nyx, then back. "It will not love you. Fae things seldom do. But it may respect the hand that bleeds honestly."
Rory took it. The cold bit clean through her palm, bracing as river water, and the blade's glow brightened where her fingers closed. Around them, the white flowers turned their faces toward her in perfect silence . Her heart was hammering . The pendant warmed at last against her chest — not with the warning pulse she knew from Hel-touched places, but in slow answer, crimson to moonsilver, as if two distant things had recognised one another across her body.
From far beyond the grove, muffled and impossible, a church clock struck. Isolde looked up at the star-torn amber sky.
"When you step out," she said, "the park will tell you a story about lost minutes. Believe it no more than you must."
"How long have we been here?" Rory asked.
Isolde walked back toward a path that had not existed until her first step imagined it, and left no footprints on the grass. "Long enough," she said, "for the world outside to have missed you. Not long enough, I think, for what follows you to have given up."
Rory closed her hand around the cold blade and followed her deeper, while behind her Nyx came apart into the grove's bright shadows and gathered themselves again, step by uneasy step, in her wake.
