Aurora left her bicycle chained to a rusted gate on the edge of Richmond Park and walked beneath the trees with both hands buried in the pockets of her coat. The park had shut hours ago. A council sign beside the gate listed closing times in peeling white letters, though someone had bent the bottom corner back and forth until it hung loose. Beyond it, the paths vanished into wet grass and black trunks. Her phone showed 01:17. No signal. No map. No helpful blue dot. “Brilliant,” she muttered. The Heartstone pendant rested against her sternum, hot enough to sting through her jumper. Its deep crimson centre held a coal-red glow. Each pulse travelled through the silver chain and into her skin: one beat, then another, slow and deliberate. The note had appeared under her flat door that afternoon, folded into a square no bigger than a stamp. COME ALONE. RICHMOND. THE OAKS THAT STAND. MIDNIGHT. BRING THE HEARTSTONE. No signature. No explanation. The paper smelled of rainwater and something sweet underneath, crushed leaves or old perfume. Aurora had spent three hours convincing herself she would not go. Then the pendant began warming against her chest. Now she walked deeper into the park, following its heat. The city had not vanished completely. London glimmered behind the trees in a low orange haze, a distant smear beneath the clouds. Traffic sighed somewhere beyond the park walls. A train clattered across tracks far off, then cut short as if someone had shut a door over the sound. Aurora stopped. The silence that followed had weight. She listened. Water dripped from branches. A leaf fell through the dark and landed near her left boot. Her own breath rasped inside the wool scarf wrapped across her mouth. Nothing else. She carried a torch in one pocket and a folding knife in the other. The knife had belonged to Silas, who had pressed it into her palm after reading the note. “You’re not going alone.” “I’m going alone.” “You’re taking the knife.” “I don’t know how to use it.” “You point the sharp bit at the thing you don’t like.” Silas had tried for a grin. It had not reached his eyes. Now, Aurora drew the torch from her pocket and clicked it on. A narrow white beam struck the path ahead. Mud shone in shallow ruts. Bare roots twisted over the ground like knuckles. The path should have led east, towards a service road and the outer fence, but the pendant pulled her left. She left the path. Brambles caught her coat. Wet grass soaked through the toes of her trainers. Every few steps, she glanced behind her. The torch showed trees. Ferns. A black ditch full of water. No one. “Get a grip, Rory.” Her voice died two feet from her face. She kept walking. The old stories called the place Isolde’s grove. Most people laughed when they mentioned it, then glanced over their shoulders before they finished the joke. A hidden clearing in Richmond Park. Stones older than the city. Flowers that bloomed through frost. A patch of ground where compasses spun and watches lost time. Eva had told her about it years ago after too much cheap wine in a Cardiff kitchen. “If some gorgeous stranger asks you to dance near standing stones, don’t,” Eva had declared, pointing a wine bottle at Aurora. “And don’t eat anything. Not a grape. Not a crisp. They’ll have you polishing goblin shoes for a hundred years.” “You’ve got a very specific fear of goblins.” “They know what they did.” Aurora had laughed then. She did not laugh now. The pendant throbbed. Heat spread across her collarbones. Ahead, wildflowers glimmered under the torch beam. Not a few stubborn winter blooms. Not a planted bed. Thousands of pale flowers filled the hollow between the trees, opening their faces towards a sky with no moon. White petals. Blue centres. Tiny red cups, bright as fresh cuts. A ring of oak stones stood around them. Aurora stopped at the edge of the clearing. The stones rose taller than she expected, each one broad and dark, their surfaces ridged with moss. Oak roots gripped them from below, although no oak grew close enough to explain it. The trunks around the clearing bowed inwards, their branches tangled overhead. The air smelled wrong. Summer soil. Rotting apples. Candle smoke. Her phone vibrated in her pocket. Aurora jerked, then pulled it out. The screen lit her hand blue. One new message. UNKNOWN NUMBER: YOU ARE LATE. She stared at it. Her thumb hovered over the keyboard. WHO IS THIS? The message appeared beneath hers at once. THE ONE WHO BROUGHT YOU HERE. Aurora’s gaze moved to the pendant. “You gave me this?” No answer. She stepped into the clearing. The flowers gave beneath her trainers with a soft, damp sigh. Their stems did not break. They bent, then lifted again after she passed. The torch flickered. Aurora slapped its side. The beam steadied, although the light had changed. It no longer looked white. A faint yellow stain bled across the grass, as though the torch shone through old teeth. Her phone buzzed. DO NOT STEP BETWEEN THE SECOND AND THIRD STONES. She looked up. The standing stones formed a rough circle. Someone had carved thin grooves into their surfaces. At first, Aurora took them for weather marks. Then her torch passed over one stone, and the grooves caught the light. Letters. Not any alphabet she knew. Hooks, spirals, lines like roots beneath pavement. She moved closer to the nearest stone. A child began humming. Aurora froze. The sound came from the trees beyond the circle. A thin, tuneless noise. The child held one note too long, dropped to another, then returned to the first. “Hello?” The humming stopped. Aurora waited. “Park’s closed,” she called. “If you’re lost, answer me.” A branch cracked. Not close. Somewhere to her right, beyond the fifth stone. She raised the torch. The beam travelled over flowers, trunks, low-hanging branches. It caught a strip of pale fabric between two trees. A small dress. No. Not a dress. A scrap of plastic snagged on a thorn. Aurora let out the breath caught in her throat. Her hand had found the folding knife without her noticing. “Fine. Great. Plastic bag. Terrifying.” The pendant flared against her skin. A soft knock came from inside the nearest standing stone. Aurora swung around. The stone stood where it had stood. Moss covered its base. Water gleamed in the carved grooves. Knock. This time, something answered from another stone across the circle. Knock. Then another. Knock. The sounds travelled around the ring, measured and polite. They never overlapped. Each stone waited for the last before it spoke. Aurora backed towards the clearing’s edge. Her heel came down on a patch of red flowers. They released a smell like pennies. The knocking stopped. Her phone vibrated again. STAY INSIDE THE RING. She looked at the screen, then at the trees behind her. The darkness between the trunks had thickened. It no longer resembled ordinary shadow. It lay in strips, layered one over another, and shifted when she did not look straight at it. Aurora’s mouth went dry. “What’s out there?” The question left her before she could stop it. For several seconds, nothing moved. Then, from the trees, her own voice answered. “What’s out there?” Same accent. Same low scrape at the end of the words. Same breathless edge. Aurora held the knife tighter. “That’s not funny.” Her voice came again, farther left. “That’s not funny.” The flowers around her ankles trembled. She did not. Not on the outside. She forced herself to look at the stones, not the trees. Eight standing stones. She counted them twice. Each sat at a different angle, as if some giant hand had shoved them into the earth and forgotten to straighten them. The note had mentioned the oaks that stand. Not the stones. Her torch beam climbed past the ring and found the trees beyond it. At first she saw only trunks. Then she noticed the roots. Every oak around the clearing had pushed up from the ground, roots braided around the stones, holding themselves upright on thick, twisted limbs. Their trunks had lifted clear of the earth. Beneath each one, darkness yawned where the soil should have been. The standing oaks had not rooted around the stones. They had stood on their roots like legs. A root shifted. Mud slid from it in slow clumps. Aurora’s torch slipped in her grip. The beam hit the ground, spun across the flowers, and landed on the gap between the second and third stones. Nothing stood there. Then the pendant burned. A red line appeared in the air. It hung between the stones, thin as a thread, beginning at the grass and stretching above Aurora’s head. The line brightened. Crimson light seeped from it, pulsing in time with the Heartstone. The gap widened without the stones moving. Cold air rushed through it, carrying a smell Aurora knew from no place on Earth: iron, smoke, deep water, and something old enough to have forgotten its name. Her phone screen went black. In its reflection, a face stood behind her. Aurora did not turn. The reflection showed only part of it: a white oval over her shoulder, too high off the ground, with a dark mouth stretched open beneath two pits where eyes belonged. The thing breathed against the back of her hair. The oak roots creaked. Aurora lifted the Heartstone in one shaking hand. Its crimson glow filled the clearing, painting the flowers and stones the colour of exposed muscle. Behind her, her own voice whispered into her ear. “Step through.”
