You are an expert fiction writer. Always keep the following rules in mind: - Write in past tense and use General English spelling, grammar, and colloquialisms/slang. - Write in active voice - Always follow the "show, don't tell" principle. - Avoid adverbs and cliches and overused/commonly used phrases. Aim for fresh and original descriptions. - Convey events and story through dialogue. - Mix short, punchy sentences with long, descriptive ones. Drop fill words to add variety. - Skip "he/she said said" dialogue tags and convey people's actions or face expressions through their speech - Avoid mushy dialog and descriptions, have dialogue always continue the action, never stall or add unnecessary fluff. Vary the descriptions to not repeat yourself. - Put dialogue on its own paragraph to separate scene and action. - Reduce indicators of uncertainty like "trying" or "maybe" When writing text: - NEVER conclude the scene on your own, follow the beat instructions very closely. - NEVER end with foreshadowing. - NEVER write further than what I prompt you with. - AVOID imagining possible endings, NEVER deviate from the instructions. - STOP EARLY if the continuation contains what was required in the instructions. You do not need to fill out the full amount of words possible.

The oaks stood in a ring at the edge of the deer path, seven of them, each as wide as a bus shelter and split down the middle as if lightning had tried to open them and failed. Frost furred the bracken around their roots. Between the trunks the air hung wrong, a shimmer like heat rising off a car bonnet in August. Rory stopped a pace short of it. Her breath smoked. The crescent scar on her left wrist itched. "You see that?" she asked. "I see it." Nyx's voice slid past her ear, dry as a leaf on tarmac. "I have not seen its like in three hundred winters. Not since before they paved the world." "Is that a yes to going in, or a warning?" "It is a door. Doors do not care which." Rory zipped her jacket to her chin. She still smelled the Golden Empress on the sleeves, ginger and fried garlic, and she held onto that. Then she stepped between the stones. The cold let go of her at once, the way a hand lets go of a wrist. Warm air folded over her shoulders. She turned. Behind her, the park was a smear of grey, the road noise from Petersham stretched into a low drone like a cello note held too long. Then it faded, and she heard only her own pulse. Nyx came through beside her. Their edges frayed as they crossed, a ribbon of black unspooling, then knitting tight into a tall silhouette with two violet points for eyes. They did not leave prints in the soft ground. Rory's boots sank an inch into moss. "Well," Rory said. "That's not December." Wildflowers ran to every horizon the trees allowed. Foxgloves leaned against cornflowers, and poppies burned red beside drifts of bluebells that had no business blooming in the same month, let alone the same field. Bees the size of her thumb worked the blossoms. Their hum had a tune in it, and she caught herself humming along. "Don't," Nyx whispered. She shut her mouth. "Was that dangerous?" "Pleasant things usually are here." They walked. The path was a strip of pale clover that seemed to unroll a few steps ahead of them. Rory pulled her phone from her pocket and thumbed the screen awake. The clock read 4:12. She stared at it. It had read 4:12 when they left the road. "My phone's stuck." "Your phone is honest. Your minutes are what have gone soft." Nyx tilted their head toward the sky. "An hour here may be a breath outside. It may also be a week. Eva will worry." "Eva always worries." Rory pocketed the phone anyway and checked her hands for grey hairs, which was stupid, and she knew it, and she checked again. The sky was the wrong shade of gold, thick as honey held to a lamp, with no sun in it that she could find. Light fell from everywhere at once. Her shadow lay pale and thin under her feet, and beside it Nyx's shadow lay dense and black, a hole cut in the world's cloth. Ahead, the clover path dipped toward a stream. Rory knelt at the bank. The water ran clear over white stones, and it ran uphill. She watched a fallen petal ride the current up a shallow rise, past a boulder, and over a lip of rock where it should have dropped. "Right," she said. "Nope. I'm not touching that." "Wise." "Is it wise, or are you just enjoying watching me flinch?" "Both." Something dry and pleased moved in the whisper. "In sixteen forty-three I would have drunk from it, to see what happened. I do not recommend the result." Rory looked up at them. Nyx stood very still, eyes fixed on the far bank where the trees thickened. Their outline had gone sharper, the way a dog's ears sharpen at a noise the owner can't hear. "What is it?" "Listen." She listened. The bees. Water sliding the wrong direction. Then, under both, a slow creak like a ship's timber, and a sigh that rolled through the branches without moving a single leaf. The sound came from all sides. It felt like being breathed on by something very large that had not yet decided whether to wake. "The trees are talking," Rory said. "The trees are dreaming. Talking would be worse." They crossed the stream on a line of stepping stones, each one worn into a shallow bowl by feet older than London. Rory counted eleven bowls and stopped counting when she noticed the stones had grown a twelfth while she watched. On the far bank the oaks crowded close, their bark carved with spirals and knotted lines. She pressed her palm to one. The carvings were warm, and they hummed against her skin like a plucked wire. The pendant under her jumper stirred. She pulled the silver chain free. The Heartstone lay in her palm, crimson and thumbnail-small, and its inner glow throbbed once, slow, the way a sleeper's eyelid flickers. "That's not meant to do that here," she said. "It only does that near a portal." "Then the grove is either lying to you or remembering something." Nyx bent closer. Their face was a smooth dark plane, but the violet eyes narrowed. "Hel and the Fae Courts share a wall, Aurora. Somewhere the wall is thin." "Somewhere here?" "Somewhere near. The solstice is close. The Veil sags like wet paper this time of year." Rory tucked the stone back beneath her jumper. It kept its warmth against her breastbone, a small coal she couldn't put out. The path climbed. The trees opened on a hollow ringed with pale boulders, and in the hollow lay a garden of glass. Not glass, she corrected, walking closer. Frost. Every blade of grass, every fallen leaf, every spider's web had frozen in the middle of some motion and hung there, sheathed in ice clear as a lens. A hare crouched among the stems, mid-leap, one hind leg tucked. Its eye held a tiny reflection of the sky. Rory circled it slowly. "Is it alive?" "It is waiting." "For what?" "I do not know." Nyx's whisper thinned. "That is what troubles me. I know most things that wait." She crouched and held her hand an inch from the hare's flank. Cold poured off it, sharp enough to ache in her teeth. The scar on her wrist flared white. She snatched her hand back and cradled it. "Don't touch anything else," she muttered, mostly to herself. "I did not touch anything at all." "Then stop looking so smug about it." They skirted the frozen garden. Beyond the boulders the ground fell away into a long meadow, and at the far end of it stood a single tree, silver-barked and enormous, its branches hung with thousands of small bells. None of them rang. The air stayed still. Yet Rory felt the ringing in her sternum, a note too low for her ears, and her eyes stung. "That's beautiful," she said, and the word felt too small in her mouth. "It is old," Nyx said. "Beauty is only what old things wear when they want visitors." She glanced at them. The shade had drifted a half-step behind her, close to the rim of her own shadow, as if wary of stepping out into that gold light. A ripple ran through their edges, black smoke pulled by a draught that didn't reach her. "You're afraid of it." "I am cautious of it." "Same thing, with better tailoring." A breath of laughter, barely there. "Walk, Aurora." She walked. The meadow grass brushed her knees and left pollen on her jeans that glittered like crushed mica. Halfway across, she looked back. Her own footprints trailed behind her in the flattened green, a neat line of boot treads, and beside them nothing. No second track. Only the ribbon of her passage, and at its far end, tiny now, the seven split oaks holding open the door. She faced forward again and kept moving toward the silver tree.
