AI The standing stones did not look ancient from a distance. They looked like weathered oak trunks someone had dragged upright in a rough ring and left to rot in the grass.
Up close, Aurora saw the grain move.
Not sway. Not bend in wind. Move.
The knots in the wood shifted like half-lidded eyes rolling to watch her pass. Pale green lichen spread across one stone, then drew back under itself as if it had changed its mind about being touched. Her fingers hovered an inch from the bark-dark surface.
“Tell me you can see that.”
Nyx stood beside her as a tall cut-out of night with two violet pinpricks where eyes should have been. Their edges bled into the shade beneath the nearest hawthorn.
“I saw it before you did.”
“That didn’t help.”
“It was not meant to.”
Aurora shot them a look, then glanced over her shoulder. The path behind had already gone strange. Richmond Park should have stretched in muddy tracks and winter-yellow grass, with the distant shapes of deer and cyclists and dog walkers. Instead a silver mist pressed low between the trees. The city had dropped away without sound. No traffic. No plane overhead. No human voice.
Only the hush.
Not silence . Something fuller. The place breathed. Leaves ticked against one another though no wind touched Aurora’s face. Somewhere deeper in the grove, water rang over stone with the bright note of glass tapped by a fingernail.
Isolde crossed the boundary first. Of course she did. Her silver hair hung down her back like poured moonlight and her boots left the grass unmarked. She passed between the standing stones without so much as brushing them, and the air around her rippled.
“You invited us in here,” Aurora called. “You could at least pretend this is normal.”
Isolde looked back, pale lavender eyes bright as frost on a window.
“Normal is a fence built by frightened minds. Come through, child.”
“Not exactly comforting .”
“The lamb asks the river for stairs.”
Aurora let out a breath through her nose.
“There it is.”
Nyx dipped their head.
“She has been restrained so far.”
“That was restrained ?”
“By her standards, yes.”
Aurora touched the pendant at her throat without thinking. The Heartstone sat warm against her skin, a small deep-crimson weight under her jumper. It had pulsed once when they stepped near the stones, not hard enough to burn, but enough to remind her it was paying attention .
“Right,” she muttered. “Fine.”
She stepped between the oaks.
Cold hit first. Not winter cold. Cleaner than that. It slid under her clothes and through her skin and came out the other side carrying something stale away with it, as if the grove had rinsed her clean in one breath. The next step landed on moss so soft it gave like thick carpet. Light changed. It lost the flat grey of an overcast afternoon and turned liquid, gold and green together, pouring down between branches that bent too high and spread too wide to belong to any trees in London.
Aurora stopped dead.
The clearing beyond the stones was gone . The little hidden patch of parkland she had expected had no place here. The grove opened into a wood that looked stitched from dream fragments and old stories. Trunks rose white as bone and black as coal and blue as bruised dusk. Some trees had bark like glass, with amber sap suspended inside as if insects and petals had been trapped in honey. Others wore leaves in impossible colours: silver, rust-red, a luminous green that seemed to light itself from within. Wildflowers crowded the ground in drifts, star-shaped and bell-shaped and feather-thin, blooming in colours she knew and a few she could not have named if someone held a knife to her throat.
“Bloody hell.”
Nyx’s voice brushed her ear though they stood a few feet away.
“Yes.”
That, more than anything, unsettled her. If Nyx sounded impressed, this place had teeth.
A flock of tiny things burst from a bank of ferns to their left. Aurora flinched and reached for the blade at her hip before she realised they were birds. Or near enough. Each had a body no larger than her thumb, with translucent wings like dragonflies and long tails that streamed sparks. They wheeled around Isolde’s head in a loose halo, singing in high glassy notes, then vanished into the branchwork above.
Aurora stared after them.
“Please tell me those don’t eat eyes.”
“Only if insulted,” Isolde replied.
Aurora swung towards her.
“You’re joking.”
Isolde only smiled and turned away.
“That’s not a no,” Aurora said.
Nyx drifted past her.
“In this place, avoid offering your name, your thanks, your iron, or your blood.”
“That sounds like the sort of information I wanted before we came in.”
“You still possess all four.”
“Great. I feel much better.”
They moved deeper along no path Aurora could see, yet the wood parted around Isolde as if she walked one laid down for her alone. Moss swallowed their footfalls. The air smelled of rain on stone, crushed mint, and something sweeter underneath, a ripeness close to decay but not tipping into it. Every so often a branch bowed overhead and dropped a bead of liquid light that vanished before it hit the ground.
Aurora kept one hand near the Fae-forged blade. Isolde had pressed it on her two nights before with the solemnity of a priest and the timing of a debt collector. The moonsilver hilt chilled her palm through the leather wrap whenever she checked it. Now the blade seemed to hum faintly against her side, as if aware it had come home.
The sound of water grew louder. They passed between two leaning yews and the trees broke open around a stream.
Aurora forgot to breathe for a second.
The water ran clear over black stone, but colour moved in it where no colour should have been. Threads of blue fire slipped through the current. Silver fish with antlers no bigger than a fingernail turned in the shallows, their scales flashing like coins. The streambed held smooth pebbles and things that were not pebbles at all but tiny carved faces, each no larger than a child’s tooth, all with closed eyes. One opened as she looked. Its stone mouth stretched in a yawn.
Aurora stepped back.
“Nope.”
Nyx crouched at the bank, more solid than usual, long fingers hovering above the surface.
“This water remembers.”
Aurora folded her arms.
“Water shouldn’t remember.”
“Everything remembers. Most things are simply not asked.”
Isolde stood on a flat rock in midstream without disturbing the current around her boots.
“Would you hear what the river keeps, Rory Carter?”
Aurora’s full name landing here made her shoulders tighten.
“No.”
“A wise answer.”
“Lovely. I’m thriving.”
She knelt instead and studied the water from a safer distance. Her reflection looked mostly right. Blue eyes. Black hair tucked behind one ear. The pale oval of her face. Then the current warped and she caught a second shape over her shoulder, tall and horned and crowned in amber light. She jerked around with her hand on the dagger.
Nothing stood there but Nyx, still crouched, and a stand of pale birches.
“Did you see—”
Nyx rose in one smooth motion.
“Yes.”
“And?”
“This place shows what clings.”
Aurora looked back into the stream. Her reflection had settled. Only her own face looked up now, strained around the mouth.
“Helpful as ever.”
She got to her feet and moved on before the water could offer another glimpse.
The wood thickened. Trees grew closer, their roots coiling above ground like sleeping serpents. Light dimmed into a green dusk though the air still held that impossible gold. Here and there she noticed objects tucked into the roots and branches: a child’s shoe gone stiff with age, a rustless key, a ring made of woven grass that had not browned, a teacup with a crack mended in gold, a fox skull threaded with tiny pearls. Offerings, she thought. Or trophies.
“What happened to the people who left those?”
Isolde ran her fingertips across a hanging chain of seedpods that chimed like little bells.
“Some left with less than they brought. Some left with more.”
“Still vague. Consistency matters.”
“You expect straight roads in a crooked kingdom.”
Aurora almost smiled despite herself.
Ahead, the trees opened onto a broad hollow where the ground dipped in a perfect circle. At its centre stood a pool black as obsidian. No ripple touched its surface. It reflected not the branches above but a sky full of unfamiliar stars.
Aurora stopped at the rim.
“It’s daytime.”
“In one place,” Isolde replied.
Nyx’s shadow stretched towards the pool and halted short, as if a leash had snapped taut.
“I dislike this.”
Aurora looked at them. “That’s new.”
“This water does not belong entirely here.”
That prickled the back of her neck. The Heartstone pendant warmed again, stronger this time, not the steady pulse she had felt near odd places before but a quickened beat, almost eager . She pressed her thumb against it through her jumper.
“Isolde.”
The half-Fae did not look at her. She watched the pool.
“The boundaries fray where longing gnaws. Some doors open by hunger.”
Aurora glanced at Nyx, then at the star-shot water.
“Is that Hel?”
“Not a door,” Nyx murmured. “A bruise.”
As if the word had struck it, the pool shivered. The reflected stars ran together. For one heartbeat Aurora saw not sky but a vast amber glow, a colour rich as spiced wine , and the suggestion of terraces heavy with vines, tables spread in endless rows, figures moving beneath lanterns the size of moons. Heat brushed her face carrying scents of roasted meat, sugared fruit, smoke, clove, wine so rich it seemed chewable .
Dymas.
The image vanished. The black surface sealed smooth again.
Aurora’s pendant burned hot enough to make her suck in a breath and yank it clear of her skin. The crimson stone held a faint inner glow.
Nyx turned, violet eyes fixed on it.
“So. That is what calls to it.”
Aurora let the pendant fall back against her chest.
“I didn’t exactly ask.”
“No,” Isolde said softly . “You were asked.”
Aurora stared at her.
“That’s meant to mean something useful, I assume.”
“It means the feast has already laid your place.”
“I’m not sitting down.”
“Yet you heard the invitation.”
The wood around them had gone quiet. Not merely hushed. Listening. Even the stream behind them had dulled.
Aurora rolled her shoulders, forcing the tension out before it locked there.
“Fine. Ancient pool. Strange realm. Cryptic nonsense. Standard day.” She nodded towards the left edge of the hollow, where a narrow break in the roots led downward between stone outcrops lit by clusters of pale fungus. “We’re not stopping here, are we?”
Isolde finally looked at her. A smile touched her mouth, brief and sharp.
“No. The grove has not shown you its heart.”
“Good. Because I’d hate to think this was the easy part.”
Nyx moved first this time, flowing towards the narrow descent with their head tilted as though listening to something underground . Aurora followed, boots scraping damp stone now that the moss had thinned. The air changed with each step. Warmer below. Richer. The scent of flowers gave way to wet earth and crushed herbs and the metallic tang that came before lightning.
The walls of the passage were not carved stone but roots packed so tightly together they formed a tunnel. They twined overhead in rib-like arches. Light leaked from fungus in veils of blue and white, enough to catch on beads of moisture. In places the roots had grown around old objects until they became part of the wall: a silver comb embedded teeth-first, a copper coin split by woodgrain, a tiny mirror clouded with age. In one knot of root a human handprint showed in perfect detail, pressed deep as if the tree had grown over memory itself.
Aurora slowed there.
“Tell me that isn’t what I think it is.”
Isolde passed her palm over the print without touching.
“The grove keeps what is given.”
“Voluntarily?”
The half-Fae’s silence answered well enough.
Aurora swallowed and kept moving.
The tunnel widened all at once and delivered them into a cavernous chamber open to the sky through a ragged circle high above. Vines draped the walls. Water fell in thin threads from the roots overhead and vanished into channels cut through the stone floor, filling the space with a constant silver murmur. In the centre rose an enormous tree.
No, not rose. Occupied.
Its trunk swelled from the rock like the spine of the place itself, broad enough that ten people with linked hands might not have circled it. The bark shimmered with colours that shifted under her gaze: pearl, ash, green, old gold. Branches spread into the open air above, carrying blossoms and fruit at the same time. White flowers the size of saucers. Dark red fruit shaped like lanterns. Tiny green figs growing beside them. Leaves silver on one side, midnight blue on the other, turning slow though no wind touched them.
At the base of the tree lay a ring of shallow bowls carved from stone. Some held milk. Some held seeds. Some held things Aurora did not want to identify.
She let out a long breath she had not realised she’d been holding.
“Right,” she whispered. Then louder, because whispering here felt rude. “This is the heart?”
Isolde walked to the tree and laid one hand against the trunk. For the first time since Aurora had known her, the Seer looked small.
“This is one of them.”
Aurora stepped closer despite herself. The bark gave off a faint light, enough to paint the scar on her left wrist in silver when she reached out. She stopped just short of contact.
The tree hummed.
Not through the air. Through her bones. A deep note, old and steady, that made her teeth ache and her chest loosen at once. Images flickered at the edge of sight: moonlit riders between trunks, foxes speaking in women’s voices, banquets laid beneath roots, infants left on blankets of fern, swords planted in black soil, lovers kissing with blood on their mouths, crowns woven from briars.
Aurora snatched her hand back though she had not touched it.
Nyx stood very still on the outer edge of the chamber, as if some line prevented them crossing. Their shape frayed at the shoulders.
“This place rejects me.”
“Good,” Aurora said, eyes still on the tree . “Nice to know it has standards.”
Nyx gave a sound almost like a laugh, thin as smoke.
One of the lantern-shaped fruits split open above them with a wet crack. Aurora’s hand went to her dagger. Thick scent spilled into the chamber at once—honey, citrus, and something red and ferrous beneath. Golden pulp glistened inside the split skin.
Isolde tipped her face up.
“It wakes.”
Aurora looked from the fruit to the bowls at the base of the trunk, then to the dark channels carrying water around the roots.
“Wakes for what?”
