AI The oak standing stones rose out of the bracken like teeth pulled from the earth.
Rory slowed at the first one and stared up at its fluted face. Weather had worn grooves into the wood until the grain looked like river maps . Silver moss clung to the base. Wildflowers crowded the roots in a ring so dense it looked planted by a careful hand rather than chance.
Behind her, Nyx drew thinner than the air around them, a tall spill of darkness with faint violet light where eyes should have been. The shade paused at Rory’s shoulder and angled their head toward the stones.
“This place tastes wrong,” their whisper brushed the back of her neck. “Old. Watched.”
Rory slipped her hand into her jacket pocket and closed her fingers around the moon-cold leaf of the Fae blade. The metal bit her skin through the cloth, clean and sharp, no warmth in it at all.
“Comforting,” she muttered.
Isolde moved ahead of them without a sound. Her silver hair caught scraps of light between the trees, a pale river down her back. She did not leave a print in the damp earth. Rory watched the ground after each step and saw only bent grass springing up again behind her.
“Do not step on the roots,” Isolde called over one shoulder . “They listen.”
Rory gave the nearest oak a wary look. Its bark had split in long ridges that resembled knuckles and faces if she squinted. “I’ll keep that in mind.”
“Keep more than that,” Nyx murmured.
The grove waited beyond the stones, and the moment Rory crossed the threshold, the air changed.
It dropped cool against her face. Not cold. Not quite. More like the breath before rain when the clouds had not opened yet. The smell hit next: wet stone, crushed leaves, something sweet and sharp under it, like green apples cut with a knife. The sounds of Richmond Park fell away at her back, the distant traffic and dog barks and voices thinning until they seemed to belong to another day.
Ahead of her, the clearing stretched wide and still.
Wildflowers grew in drifts across the ground, not in neat patches but in swathes of colour that looked poured there. Blue, gold, violet, white. Their heads turned as if tracking them, though no wind touched them. The grass between them shone with a pale sheen, each blade tipped with dew that caught the light from nowhere Rory could name. The clearing itself sat inside a ring of ancient oaks so thick and twisted they might have belonged to a story older than language.
Rory took one step, then another.
The ground did not crunch under her boots. It gave a little, soft as felt.
“Does it always look like this?” she asked.
Isolde glanced back, pale eyes catching what little light filtered through the canopy. “No.”
Rory waited. Isolde only walked on, silver hair brushing the dark of her cloak.
Nyx leaned close enough that Rory felt the edge of their presence like a draft through a crack. “That answer gave us nothing.”
“It gave us less than nothing,” Rory said.
A dry sound from Nyx. Not quite laughter, not quite breath . “You’re learning.”
She shot them a look, then stopped dead.
The flowers ahead had opened wider since she first saw them. She could swear they had shifted from blue to a colour with no name, something between pearl and smoke . A cluster of stems bent as she looked at them, then straightened. She crouched before one and reached out a careful finger.
The blossom folded shut the instant her nail brushed it.
Rory jerked her hand back.
A line of laughter whispered through the grass.
She froze.
Nyx’s shape sharpened at her side, the edges of their shadow-body tightening. “You heard that.”
“I heard that.”
Isolde glanced over, her expression unreadable . “The grove noticed your curiosity.”
“That’s not supposed to be unsettling,” Rory said.
“It would be a poor grove if it did not know you were there.”
Rory rose slowly and scanned the trees. The trunks stood close in places, then opened wide in others, creating lanes and alcoves and odd pockets of shade. In one shadowed bend, she caught sight of something that made her chest tighten: a shape like a stag made entirely of light, thin as smoke, standing between two roots. It lifted its head at her, antlers branching like frost, then broke apart into a flock of pale sparks that drifted upward and vanished into the leaves.
She stared after it.
Nyx followed her gaze. “You saw it too.”
“I saw something.”
Isolde’s mouth curved at one corner. “Not all things wish to be kept.”
Rory rubbed her thumb against the scar on her wrist. The crescent mark tingled beneath her skin. She looked down and found the Heartstone pendant resting against her chest, its crimson surface pulsing once through her shirt, a dull beat like a hidden ember. Warmth spread from it in a quick throb , then faded.
Her stomach tightened.
Nyx noticed. Of course they did.
“That trinket recognised something,” they whispered.
“It did nothing of the sort,” Rory said, but her voice came out rougher than she meant .
The pendant pulsed again, faint and stubborn.
Isolde’s gaze flicked to Rory’s chest. “It remembers a door.”
Rory let out a short breath through her nose. “Brilliant. I hate that.”
Isolde continued into the grove as if the conversation had finished. Rory exchanged a look with Nyx and followed.
The deeper they went, the stranger the place became.
The oaks thickened into a hall of trunks, their branches interlacing overhead until they formed a living roof stitched with leaves. Pale shafts of light slipped through in slanted ribbons, but the colours of the grove did not come from the sun. Moss glowed along the roots in faint green lines, and tiny white things—moths, maybe, or stars given wings—floated among the branches with no sound of movement at all.
Rory brushed past a fern and nearly pulled back when its fronds shivered as if touched by a passing hand. She looked over her shoulder. No one stood there. Nyx drifted a step behind, their form dark against the luminous greens, and even they seemed quieter here, as if the grove pressed its own hush over them .
A narrow stream cut through the clearing ahead. Rory heard it before she saw it, a low chiming sound like water running over glass. She stepped closer and looked down.
The water ran clear enough to show a bed of smooth black pebbles, but the surface held reflections that did not match the sky. She saw clouds, then a spill of gold light, then the outline of a city she did not know, towers and bridges mirrored upside down in the current. The reflection shifted as she stared, and for one sharp second she saw her own face looking back from somewhere under the water, eyes bright blue and wide with surprise.
She stepped back so fast her boot skidded in the moss.
“Did you see that?” she asked.
Nyx knelt at the bank without touching the water. Their shadowed fingers hovered a breath above it. “A place that remembers other places.”
Isolde crouched beside a fallen log, plucked a white flower from the moss, and held it between two fingers. “The brook keeps what it is given. A sound. A face. A year. If you linger, it may take more.”
Rory glanced at the stream again. The water looked harmless now. That made it worse.
“Take more?” she echoed .
Isolde tucked the flower behind her ear. “An hour inside can steal a day outside. A day can pass like a blink. Time bends where roots run deep.”
Rory stared at her. “You could have led with that.”
“And spoil the surprise?”
Nyx’s whisper slid in from Rory’s left. “I hate that I understand her.”
Rory gave a bark of laughter before she could stop herself, and the sound seemed to lift the hush of the grove for a heartbeat. The flowers at her feet trembled . Somewhere above them, a bird called once, but the note came out in three tones at once, layered and thin, like someone playing the same voice through glass.
Rory looked up.
The canopy overhead had opened into a round space where the branches did not touch. In the gap, the sky showed through—not the grey sprawl she expected over London, but a wash of late evening violet shot through with a pale gold seam. Stars hung there, though the sun had not gone down outside yet, not if the light at the edge of the clearing still held any truth.
Her skin prickled. “That’s not right.”
Isolde’s eyes moved to the sky, then back to Rory. “What is right for one road is ruin for another.”
“That’s not a real answer.”
“It was not meant as one.”
They walked on.
The path narrowed between roots the size of walls. Rory ran her fingertips across one as she passed. The bark felt smooth in places, warm in others, and beneath it she sensed a slow pulse , low and steady, as if the tree carried a buried heart. Tiny pale flowers bloomed from cracks in the wood at shoulder height, each one shaped like a spiral shell.
Nyx stopped beneath one branch and tilted their head. “There’s a mark here.”
Rory looked where they pointed.
A ribbon of silver had been tied around the limb years ago, maybe centuries, its ends frayed to threads. Symbols scratched into the bark ringed the branch in a circle. Some had softened with age. Others looked fresh enough to bleed sap. Rory leaned closer and traced one shape with her eyes: a clawed spiral, a crescent, a line that forked like antlers.
“What does it mean?” she asked.
Isolde stood beside her, the hem of her cloak brushing the moss without leaving a trace. “A promise. A warning. A door left shut.”
Nyx angled closer, the dim violet of their eyes brightening. “From whom?”
Isolde turned her gaze toward the deeper trees. “From those who knew enough to fear what answered.”
Rory frowned at the sigils. They pulled at something in her head, not a memory exactly, more a feeling of standing on the edge of a thought she could not seize. The Heartstone pendant warmed again against her sternum, not enough to burn, just enough to notice.
The air around the branch stirred.
Rory glanced up sharply .
Between one heartbeat and the next, the shadow under the branch detached from the tree.
It rose in a slender shape, human for the span of a breath, then stretched longer and thinner than any body should have been able to hold. A face seemed to form in it, vague as smoke, and two pale points gleamed where eyes might live. The thing drifted toward the far side of the path, pausing as if to study them.
Nyx moved first. Their own form sharpened, dark and tall, shoulders squared. The two shadows faced each other in the undergrowth, one living, one borrowed.
Rory’s hand went to the Fae blade.
The moonsilver felt colder than the air.
“Rory,” Nyx whispered, “don’t—”
“I’m looking,” she snapped softly .
The thing in the tree-shadow bent like a bowing figure, then slipped sideways into the bark and was gone . The woods held still again.
Rory lowered the dagger a fraction and drew in a slow breath.
“Tell me that happens all the time,” she muttered.
Nyx’s shape eased, though their voice stayed thin. “Not in front of me.”
Isolde watched the place where the shadow had vanished. “The grove has begun to know your names.”
Rory held that look for a second, then shook her head. “That is not reassuring.”
“No,” Isolde agreed, already walking. “It was not meant to be.”
They followed her deeper until the trees thinned around a wide circle of standing stones half-swallowed by roots and ivy. Each stone rose higher than Rory, its surface carved with channels that held moon-bright water or sap or something she could not name. The marks on them formed spirals, ladders, and long elegant lines that looked almost like script. At the centre of the ring stood a bowl of black stone filled with rainwater so still it reflected the sky from the wrong angle.
Rory stopped at the edge of the circle.
The air here felt thicker, charged . The pendant under her shirt thudded once against her chest, warm and insistent.
Nyx drifted to her side and looked at the stones. “This place keeps its bones in the open.”
Rory took one step toward the circle and felt every tiny hair on her arms lift. The Fae blade cooled in her grip. The stream behind them chimed. Somewhere far off, deep in the trees, something answered with a note so low she felt it in her teeth.
Isolde reached the centre of the ring and turned back to face them.
“Come,” she said, and the water in the black bowl shivered, though no breeze touched it.
