AI The Heartstone pendant burned against Rory's sternum.
She pressed her palm flat against the silver chain, feeling the crimson gem pulse beneath her fingers like a second heart. Three beats. Pause. Three beats. The rhythm matched nothing in her chest, nothing human.
"Bloody hell," she whispered.
The standing stones of the Fae Grove rose from the darkness around her, ancient oaks twisted into shapes that suggested doorways, arches, things that had once been trees and were no longer. Richmond Park lay silent beyond them, but silence here meant something different. The kind that pressed against her eardrums and made her swallow to pop them.
She had come for Eva.
Her best friend had sent a message three days ago, the last before her phone died: *Come to the grove. Midnight. Don't tell anyone. I found something.* Then nothing. No read receipts. No missed calls. Just the silence of a phone that had stopped being a phone.
Rory had known better. Everyone knew better. The Grove was Isolde's territory, and Isolde did not suffer trespassers kindly. But Eva had been drowning, and Rory had always been the one to throw the rope.
The pendant pulsed again. Warmer now. Hungry.
She stepped between the stones.
The air changed immediately. Not temperature, exactly, but pressure . The weight of a held breath. Wildflowers bloomed at her feet in colours that had no names, their petals shifting when she wasn't looking directly at them. She kept her eyes forward, on the path that hadn't existed moments before, a ribbon of pale earth winding deeper into the grove.
Footsteps behind her. She spun.
Nothing. Only flowers, only dark, only the particular silence of a place that had forgotten how to be a forest.
"Hello?" Her voice came out wrong, flattened, as if the air itself resisted carrying sound.
The pendant burned hot. Rory clutched it through her shirt, wincing at the heat, and kept walking.
The path forked. She chose left, then right, then left again, following the pull of the pendant like a compass needle seeking north. The grove rearranged itself around her, paths closing behind, new ones opening. She passed the same gnarled hawthorn three times, each version slightly wrong, its blossoms black instead of white, white instead of black, then gone entirely, replaced by a stone that wept sap.
Time moved strangely here. She knew this. An hour inside could be minutes outside, or days. She had no way to tell which it was. Her phone showed 11:47 PM, but the numbers flickered when she glanced at them, 11:47 becoming 11:74 becoming something with too many digits to read.
Something moved at the edge of her vision.
Rory stopped. Held her breath. The grove held its breath with her.
A shape detached itself from the darkness between two oaks. Tall. Wrong proportions, limbs too long, joints bending backwards. It stood perfectly still, watching her with eyes that reflected no light, only swallowed it.
She did not run. Running was how you died in places like this. She had read the stories, heard the warnings from Silas when he was sober enough to speak in complete sentences. The Grove fed on fear, on panic, on the particular terror of prey that knew it was prey.
"Isolde?" The name tasted of ash.
The thing tilted its head. The motion was too slow, too deliberate, a predator calculating angles. It took one step forward, and the ground beneath its foot bloomed with flowers that screamed when it lifted its weight again.
Rory reached for the pendant. The crimson gem flared, and the thing recoiled, pressing itself flat against the nearest oak. The bark split around it, wood knitting over its form like a mouth closing.
"Not yours," Rory said. Her voice steadied. "I'm not yours."
She walked past it. The flowers stopped screaming. The thing did not follow, but she felt its attention on her back, patient and ancient and utterly inhuman.
The grove opened into a clearing she didn't remember from any map, any story, any warning. A circle of mushrooms, pale and luminous, ringed a figure seated on a stone that might have been a throne or a grave marker. Eva. Rory's heart hammered against her ribs, a trapped bird.
"Eva!"
Her friend did not move. Her head hung forward, black hair obscuring her face. The mushrooms pulsed in rhythm with the Heartstone pendant, crimson light washing over the clearing in slow waves.
Rory ran the last twenty feet. Grabbed Eva's shoulders. Shook her.
"Eva, wake up. Eva, it's me, it's Rory, I came, I came like you asked, please—"
Eva's head snapped up.
Her eyes were wrong. Too wide, pupils blown to black pools that drank the mushroom light. Her mouth opened, and what came out was not her voice, not any voice Rory recognised, but a sound like wind through dead leaves, like a door opening on rusted hinges, like something learning to shape itself into speech.
"She's not here," Eva's mouth said. "She never was. You brought her the pendant. You brought her the key. The Grove thanks you for the offering."
Rory stumbled backward. The mushrooms brightened, their pale caps splitting to reveal rows of tiny teeth.
"What are you?" Her hand found the pendant. It burned, seared, but she did not let go. "Where is she? Where's Eva?"
The thing wearing Eva's face smiled. Eva's smile, Rory's friend's particular crooked grin, stretched too wide across too many teeth.
"She's been here three days. Three days of your time. She's been waiting for you to bring the rest." The smile did not waver. "The pendant opens doors. You knew that. Everyone knows that. You just didn't know which doors."
Behind Eva, the air tore open.
Not a door. A wound. A rip in the fabric of the grove, and through it Rory saw not Richmond Park, not London, not any place she recognised, but a vast darkness filled with shapes that moved with purpose, with hunger, with the patient attention of things that had waited since before human memory.
The Hel portal. The pendant had been leading her to it. Had been warming, pulsing, singing her toward it since the moment it appeared on her doorstep three weeks ago, silver chain and crimson stone and no note, no explanation, only the faint warmth that had never quite gone cold.
"You gave it to her," Rory whispered. "You gave her the pendant. That's why she came here. That's why she—"
"She wanted to see you," Eva-thing said, and the voice layered over itself, harmonics of something beneath, something vast . "She wanted to show you what she found. What she became. The Grove offers transformation, little human. She accepted. You will too. The pendant has chosen you. The pendant always chooses."
The portal widened. Shapes pressed against it from the other side, flattening against the membrane of torn air, leaving smears of darkness that did not fade.
Rory felt the pendant's pull intensify, a physical tug at her sternum, at her mind, at something deeper that she didn't have a name for. It wanted to be through. It wanted to be home. It had been waiting in her world, in the human world, for someone to carry it back, for someone to open the way.
She had been the key all along.
Eva-thing stood. The mushrooms parted for her, their teeth clicking in rhythm. She moved toward Rory with Eva's walk, Eva's sway, Eva's particular way of favouring her left hip from an old injury that had never quite healed.
"You could stay," Eva-thing said. "The Grove is kind to those who accept its gifts. She is happy here. She is more than she was. You could be more too."
The portal screamed. Not a sound, exactly, but a pressure, a wrongness that made Rory's teeth ache and her vision swim with colours that had no names. Through it, she saw them. The Hel. The things that had been before humanity, that had shaped the dark places of the world, that had waited in the spaces between stars for the doors to open.
The pendant burned. Rory clutched it, and for a moment she considered letting go, considered letting it pull her through, considered becoming more, becoming other, becoming anything that wasn't this, wasn't trapped in a grove that breathed and watched and hungered.
Eva-thing reached her. Cold fingers, wrong temperature, gripped her wrist. The crescent scar on Rory's left wrist, the one from the childhood accident, the one she had never thought about in years, began to ache. To burn. To match the pendant's heat.
"Let go," Eva-thing whispered, and the voice was almost Eva's, almost her friend, almost human . "Let it take you. The Grove will keep you safe. The Grove will keep you forever."
Rory looked at the portal. At the things pressing against it, flattening themselves against the tear, waiting.
She thought of Cardiff. Of her father's disappointed face when she'd left Pre-Law. Of her mother's Welsh lullabies, sung badly, sung with love. Of Silas pouring her a pint at 2 AM when Evan had finally crossed a line she couldn't uncross. Of Yu-Fei Cheung's Golden Empress, the greasy comfort of late-night dumplings, the way the restaurant smelled of star anise and possibility.
She thought of Eva, who had fled to London first, who had sent for her when the darkness came, who had known, in the last moments of herself, that Rory would come.
The pendant pulsed . Three beats. Pause. Three beats.
Rory smiled. It was not a happy smile. It was the smile of someone who had found a way out of a trap, who had seen the shape of the cage and knew which bars were weak.
She grabbed Eva-thing's wrist. Both wrists, the scar pressed against cold wrong flesh, and she pulled.
Not away. Through.
The Grove screamed. The mushrooms shrieked. The portal tore wider, and Rory stepped into it, dragging Eva-thing with her, dragging the thing that wore her friend's face into the darkness between worlds, into the space where the Hel waited with open mouths and patient hunger.
The pendant flared once, blinding, and then—
Silence.
Then: the sound of running water, of a city waking, of a phone buzzing with a message from a number she didn't recognise.
*Rory. I'm home. I'm safe. Thank you for coming. I love you. — Eva *
She stood in Richmond Park, at the edge of the Grove, the standing stones dark and ordinary in the grey light of dawn. Her clothes were torn . Her wrists burned. The pendant lay cold against her chest, inert, spent.
Behind her, the oaks whispered. Ahead, London waited, indifferent and alive and full of doors that stayed closed.
Rory walked toward the road. She did not look back.
But she kept her hand on the pendant, and she felt, beneath the cold silver, the faintest warmth . A heartbeat. A promise.
The Grove was not finished with her. The Grove was never finished.
She would be ready.
