AI Rory regretted coming the moment the park swallowed the road noise behind her.
One second there had been the low, constant London hum beyond the iron railings—late buses, tyres hissing over wet tarmac, somebody laughing too loudly somewhere they shouldn’t—and the next there was only the scrape of her boots on the path and the hard, patient breathing of the dark.
She stopped under the spread of a bare-limbed tree and looked back.
The gate she’d slipped through sat thirty yards away, black bars slick with mist. Beyond them, the city glowed in a dirty orange haze. Near enough to touch, it seemed. Safe in the stupid, ordinary way of traffic lights and kebab wrappers and drunks arguing outside pubs. Yet the path between her and the gate already looked longer than it should have, stretched thin through the trees like something pulled.
“Right,” she muttered, because silence felt too much like permission.
Her own voice fell flat. No echo . No bounce. The night took it and kept it.
She wrapped her fingers around the Heartstone through her coat pocket. The deep crimson gem had been warm all evening, a small insistent heat against her hip while she’d tried very hard to do sensible things instead—wash up the mug by the sink in the flat above Silas’s bar, answer Eva’s messages, tell herself that strange magical jewellery was now somehow just another item on the list of things she lived with. But around half eleven it had gone from warm to almost hot, pulsing in a slow, living rhythm.
When it wakes, go to the grove alone.
The note had been tucked into the little box with the pendant months ago. No signature. No explanation. Just those six words in a neat, old-fashioned hand.
At the time she’d thought it dramatic nonsense. Now she was standing in Richmond Park past midnight, damp hair sticking to the back of her neck, because apparently her capacity for ignoring terrible ideas had limits.
She took out the pendant and let it hang free on its silver chain. In the dark, the stone held a faint inner glow, not enough to light her way, only enough to look indecently alive. It pulsed once against her palm. Warm. Waiting.
“All right,” she said quietly . “I’m here.”
Nothing answered.
She moved off the path and into the trees.
The grove was never obvious. That much she knew. Ask ten people about it and nine would laugh or tell you not to be daft, and the tenth would go slightly careful around the eyes and say it was in Richmond Park if it wanted to be. A hidden clearing. Fae-touched. A pocket place where the world folded badly.
Rory had found weirder things since coming to London. That did not make this feel less foolish.
Wet grass soaked the hems of her jeans. Thorny scrub snatched at her sleeves. The beam of her phone torch slid over roots and low branches and patches of pale flowers that should not have been blooming in February. White petals, open and immaculate in the cold. Then blue ones. Then a drift of foxgloves lifting their throats toward a moon hidden behind cloud. The air smelled wrong too—green and sweet, as if summer had been cut open somewhere nearby.
She crouched beside a clump of primroses and touched one. The petals were real. Cool, silky, beaded with mist.
Her left wrist brushed a bramble. The small crescent scar there prickled, an old sting waking in the skin.
No wind moved through the trees, but something clicked in the darkness ahead. A dry wooden sound. Then again. Like two sticks tapped together with patient, measured force.
Rory straightened slowly .
“Deer,” she said, though she didn’t know why a deer would make that noise .
Another click. Closer now. Then silence .
The pendant gave a stronger pulse of heat.
She followed it.
The ancient oak standing stones appeared one by one between the trunks, not looming exactly, but present in the way certain old buildings are present, as if the land has learned to think around their weight . They ringed a clearing no bigger than a village green. In her phone’s weak light they looked almost grown rather than carved, each stone dark and ridged like bark, thick as tree trunks and older than the oaks surrounding them.
Wildflowers spread inside the ring in impossible abundance. Bluebells, poppies, daisies, foxgloves, buttercups, things she could not name. Their colours should have looked absurd in the dead of night. Instead they seemed muted, secretive, as if they held their brightness in reserve.
Rory stood just outside the boundary and felt the tiny hairs on her arms lift.
The city had vanished entirely. Not faded—gone. No traffic. No aircraft. No distant siren. Even the park’s normal noises had thinned to nothing. No fox bark. No rustle of birds settling. No mutter of leaves.
Only her own breathing.
And beneath that, after a moment, another sound.
A soft humming.
She frowned and held still. The note didn’t come from any direction she could place. It seemed to rise from the flowers themselves, from the damp earth under them, from the stones. Not a tune exactly. Only a thread of voice, low and almost conversational. The kind of sound somebody makes without realising when they’re busy with their hands.
Her mouth went dry.
“Brilliant,” she whispered.
The pendant burned warm in her palm.
She stepped between two stones.
The shift was subtle enough that she nearly missed it. The air changed first. It thickened, carrying a sweetness too rich to be natural, floral and rotting at once. Then the dark sharpened. Edges grew cleaner. She could see farther into the clearing without her torch, as if the night inside the grove obeyed different rules than the night outside.
Her phone flickered . The light dimmed, flared, dimmed again.
Rory glanced at the screen.
00:17.
She walked three more paces, looked again.
00:17.
No signal. Battery seventy-two percent.
The humming stopped.
She lifted her head.
Every flower in the clearing seemed to be facing her.
Not all at once. Not in any dramatic, impossible turn. It was simply that she had not noticed before how many pale disks and bell-mouths angled in her direction, how the foxgloves dipped, how the poppies bent on their stems. Hundreds of small, attentive faces tilted toward her boots.
A stupid chill slid down her spine .
“This is why normal people stay home,” she said.
Her voice still sounded wrong here—too close to her ear, too soft.
She forced herself onward, choosing a line through the flowers where the ground looked less uneven. She had come because the Heartstone had led her. Because an unknown benefactor with exquisite timing and no manners had left her a puzzle, and every instinct she possessed told her the answer sat somewhere in this clearing. She could turn around now, go back to the gate, climb into bed and call the entire thing a fit of temporary insanity.
The problem was the pendant.
It wasn’t just warm anymore. It was pulling .
Not physically. Nothing dragged at the chain. But the heat gathered to one side of the stone, a steady pressure against her skin that made her hand want to turn, want to point. Like the strange old lodestone compasses they kept in glass cases in museums, except this one beat like a heart.
Toward the centre of the grove.
Rory swallowed and followed.
Something moved at the edge of her vision.
She turned sharply , torch up.
Nothing. Only standing stones and flowers and the black columns of trees beyond. Yet a moment earlier she would have sworn there had been a shape slipping between two of the stones—too tall for a fox, too narrow for a deer, dark against dark.
She listened.
There it was again: click. Click.
This time it came from behind her.
She spun.
Nothing.
The second sound was not quite a match to the first . Not wood on wood. More like a heel tapping stone.
A step, if the foot making it had joints in the wrong places.
Her skin tightened over her bones.
“All right,” she said into the clearing, her voice steadier than she felt. “If somebody’s there, this is deeply unhelpful.”
No answer.
A laugh would almost have been better. A threat, better still. Threats were comprehensible. They came from people with motives. This silence had intention without shape.
The pendant flared hot enough to sting. She hissed and nearly dropped it. Crimson light welled inside the gem, thin but vivid, bleeding through her fingers.
Ahead, among the flowers, the ground dipped.
At first she took it for a shallow hollow where rain had gathered. Then she saw the rim.
Roots. Great twisted roots from no visible tree, braided through the earth in a rough circle perhaps six feet across, as if something beneath the clearing had pushed upward and been held down. The flowers around the ring were wilted . Not dead exactly, but bowed away from it, their stems strained, petals curled inward like fists.
Cold breathed out of the centre.
Not winter cold. Not ordinary night chill . This was the dry, mineral cold of a cellar door opened after years, of stone that had never seen sunlight, of air shut away with old things and older grief.
The humming resumed, very softly .
Rory stopped at the edge of the root-ring. Her breath smoked once in front of her and vanished.
The pendant was almost too hot to hold. The warmth pulsing from it should have been comforting . Instead it felt feverish, frantic.
Hel portal, she thought, and the words arrived fully formed before she had time to ask where they’d come from.
The groove of dread inside her deepened.
A portal. Here.
Wrong place. Wrong feel. The grove’s strangeness had been lush, green, overripe. This was something else entirely, something dead and tidy and patient. The flowers knew it. The air knew it. Even the stones seemed to lean subtly away.
Her phone screen blinked in her hand without warning.
00:17.
Then 03:41.
Then 00:17 again.
Rory locked it and shoved it into her pocket before she could watch it do anything worse.
The cold hole in the earth was not a hole at all. Looking straight at it, she saw only a darkness deeper than the night around it, a blackness so complete it refused shape. No stars reflected in it. No edges caught light. Yet every now and then it seemed to narrow into a crack, then widen again, as if perspective had given up.
The humming stopped on a breath.
From somewhere beyond the stones, a voice said, “Rory?”
She froze.
Male. Soft. Familiar.
Not possible.
For a moment her mind supplied the wrong face anyway, because fear is lazy and reaches for old injuries first. Evan standing behind her with that patient, placating tone he used before he started in on all the ways she’d disappointed him. Rory, don’t be dramatic. Rory, listen to me. Rory—
She shut the memory down hard enough to make her jaw ache.
No. Evan was not here. Evan was nowhere near here. This was London, not Cardiff, and she had spent too much of her life learning the difference between fear and fact to surrender to the first voice in the dark.
She turned slowly , keeping one hand on the Heartstone.
The clearing stood empty.
“Nice try,” she said, because the alternative was screaming .
A flower brushed her ankle.
She jerked back. It was only a foxglove bending under its own weight , except there was no wind, and after a second three more stems leaned toward her in the same smooth, deliberate motion.
Then all at once every blossom within a yard of her bowed flat to the ground.
Something passed through them.
Not visible. Not fully. Only a distortion, a seam in the air, moving on a curving path around the root-ring. The flowers bent under its progress and slowly lifted again behind it. One by one. Round and round.
Counting her.
Rory pivoted with it, pulse pounding high in her throat. “What are you?”
The seam stopped.
Silence pressed in.
Then, from directly behind her left shoulder, a woman’s voice said in a near-perfect imitation of her own, “What are you?”
The words hit her like a shove.
She stumbled away from the sound and nearly put a foot into the black centre. Cold surged up her leg. The pendant blazed in her fist, crimson light spilling between her fingers in thin sharp lines.
Around the clearing, the standing stones had changed.
Or she had.
They seemed farther apart now, their gaps wider, the trees beyond them deeper and more numerous than before . No glimmer of the path. No suggestion of the gate. Only trunks receding into a darkness that looked furnished, inhabited.
The seam in the air moved again. Faster.
It passed between two stones and came on. Flowers flattened in a line. Frost silvered the grass under nothing Rory could see. The sweet summer smell of the grove retreated before it, replaced by that sealed-cellar cold.
Rory backed away, mind racing . Do not run blind. Do not step into the centre. Do not let it behind you.
The useful thoughts came crisp, one after another, the way they always did when panic wanted the wheel. She shifted her grip on the chain and let the Heartstone hang free.
The gem swung once, twice, then pointed not at the dark ring now but at the thing approaching it, the crimson glow brightening in direct response.
So it could find the portal. Perhaps it could close one. Perhaps that was why she’d been sent here in the first place. Perhaps she was about to test an unproven theory against an invisible horror in a pocket of fae night where time had started slipping its teeth.
Excellent.
The air in front of her puckered.
For one impossible second she saw it.
Not clearly. Never clearly. A suggestion of height, narrow shoulders, too many angles where a body should curve. A face that wasn’t a face, only a smooth blankness with depth behind it, like looking through a window into a room with no walls. Cold streamed from it. The flowers nearest it blackened at the edges and then, just as quickly , righted themselves again, as if the grove refused to let the damage settle.
Rory’s breath caught.
The thing tilted its head with grotesque, birdlike curiosity.
Then, in Eva’s voice this time—warm, worried, painfully real—it said, “Rory, come back.”
That nearly did it.
For one wild second every part of her wanted to answer, wanted to run toward the sound because Eva meant flat lights in the kitchen and takeaway cartons and someone solid enough to thump when the world turned strange. The ache of homesickness hit so hard it felt physical.
She bit the inside of her cheek until she tasted copper.
“No,” she said.
The thing took one silent step forward.
Rory raised the Heartstone between them.
The crimson gem flared. Light cracked across the clearing in a pulse , brief and brutal as a struck match magnified a hundredfold. The standing stones groaned. The root-ring shuddered. From the black centre came a sound like distant ice breaking.
The thing recoiled.
Not far. Not enough. But for the first time it changed shape in something like alarm, edges fraying, blank face rippling as if a hand had disturbed dark water.
Rory saw her chance and hated it immediately.
She would have to get closer to the ring.
Of course she would.
The grove held its breath around her. Even the false voices went still.
Clutching the burning pendant so tightly the chain cut into her palm, Rory stepped toward the cold at the centre of the flowers, while something unseen circled back through the dark to meet her.
