Frost had turned Richmond Park into a photograph of itself — white bracken, white grass, oaks standing black and certain against a bruised December sky. Rory's breath hung in front of her face and drifted apart, and she counted it a small victory that her hands weren't shaking. Five nights until the winter solstice. Isolde had chosen the date the way a surgeon chooses a blade. Her instructions, delivered three nights ago beneath the steaming awning of the Golden Empress while Yu-Fei pretended very hard to stack bowls, had been characteristically unhelpful: When the deer will not cross, seek the brothers of one root. Knock with what the sun refuses. Do not eat. Do not drink. Do not thank anyone. The deer had been the first strange thing. A fallow doe and a young stag stood at the edge of a clearing, ears forward, bodies angled to bolt — and simply would not step past a certain line in the grass. Rory watched the doe try twice, shy back as though from a wall of glass, and give up. The brothers of one root were the second. Two oaks rose side by side from a single gnarled crown, ten feet apart, except they were no longer oaks. They were stone. Bark had fossilized into grey granite grain, and the gap between them held a darkness that had nothing to do with evening. The frost lay white across the whole field and stopped between the two trunks in a clean ruled line, as if someone had drawn it there with a ruler. The air in that gap trembled faintly, the way heat shivers over tarmac. In December. "There," Nyx said. Nyx walked beside her looking — as always — like a place where the night had forgotten to end, six feet of living shadow with two faintly glowing violet eyes. Tonight they were fully solid, boots printing the frost, breath not misting because Nyx's kind didn't breathe for warmth. "Where? I see trees." "A seam. The Veil, fraying at its hem." Nyx's voice was always a whisper carried on wind that wasn't blowing. "It shivers like water standing on its side. The pendant?" Rory touched the chain at her throat. The Heartstone hung cold and quiet against her sternum, its crimson glow dimmed to almost nothing. "Silent. So this isn't a door down." "Not down. Sideways." Nyx studied the gap with something like hunger, or its cousin. "I have not been sideways in a long while." "Knock with what the sun refuses," Rory quoted. Nyx lifted one black hand and pressed its palm flat against the trembling air. The seam dilated like a pupil. The shimmer spread outward until it swallowed the gap between the stones, and Rory's last rational thought was that she was about to walk into what was essentially a soap bubble the size of a doorway — and then the bubble popped over her entire body at once, a film of cold breaking across her skin, her ears popping as if she'd dropped ten feet in a lift. The sound of London — distant traffic, a plane, wind in bare branches — was simply amputated. Gone, mid-syllable. She was breathing summer. Warm air, thick and green, smelling of rain on hot stone and honeysuckle and something sweeter underneath that she couldn't name. The light was the second impossible thing: sourceless, silver-white, like moonrise happening at noon. Above her the sky was the colour of the inside of a pearl, and low on the horizon hung a white disc that could not decide whether it was sun or moon. Flowers everywhere. Foxgloves and poppies, snowdrops and bluebells and meadowsweet, all blooming at once in defiant wrongness, banked along a path of dark moss that wound away between the trees. Dew hung suspended in the air around them, drifting downward so slowly it had changed its mind about falling. "Okay," Rory said, and her voice came out flattened, swallowed by the hush. "Okay." Behind her, Nyx had gone very still. When she turned, they were flexing their hands, opening and closing them, staring at their own fingers. "I have weight," Nyx said softly. "Aurora. I have weight." Then Rory saw the third impossible thing. On the pearl-lit moss at Nyx's feet lay a shadow — thin, grey, faint — and it copied them a half-second late, arms rising after the arms had risen. All around the clearing, the grove's own shadows had begun to lean toward Nyx, the way plants lean toward a window. "I haven't cast one of those since 1643," Nyx murmured. There was wonder in the wind-voice, and something under the wonder that Rory decided not to look at directly. They walked. The moss swallowed their footsteps and returned them a half-beat late, so that Rory kept flinching at echoes of herself. The flowers turned as she passed — not all at once, not obviously, but she caught them at it, foxglove heads swinging gently back toward her like a crowd pretending it hadn't been staring. She checked her phone: 4:47, the same minute it had read when they crossed, except the seconds were running backward, and the battery had fallen from eighty per cent to three in the space of a hundred steps. "Time here is a suggestion," Nyx said. "Keep your own. Count your steps if it helps." "Two hundred and six," Rory said. Somewhere ahead, a single note was ringing — high and pure, like a finger circling the rim of a glass — and it had been ringing, she realized, since the moment they'd crossed. It changed pitch as they walked, and she understood with a crawling sensation between her shoulders that the note was the grove paying attention. "Breathe through your mouth," Nyx advised. "The air here is an invitation. And don't tell it your name." The path opened into the heart of the grove, and Rory forgot, briefly, how to walk. A single oak stood there, vast beyond sense, its roots rising from the earth like the fluted pillars of a drowned cathedral — roots thick as houses, arching overhead to form walls and vaults and ribbed aisles. A pool lay black and still between the greatest of them, and it held stars. The sky above was pearl and daylight, and the pool held stars anyway. At the foot of the largest root, among a bed of white flowers not one stem of which was bent, stood a woman with silver hair falling to her waist. There were no footprints behind her. There was no path to her. The flowers around her feet stood as crisp and unbowed as if no one had ever stood there at all. "You found the door," Isolde said. Her lavender eyes were the colour of the last minute before dawn. "Most people walk past doors their whole lives and call it scenery." "You said knock with what the sun refuses," Rory said. "That was almost a straight answer." "Almost is the most I can afford." The Seer's gaze dropped to Rory's throat. "Show me your pulse." Rory lifted the pendant. In the grove's sourceless light the Heartstone glowed like an ember drowned in honey, and it was still — no warmth, no beat. "It races for one door and sleeps before another," Isolde murmured. "It beats for a door it has not met. Five nights from tonight the year hinges on its darkest tooth, and the Veil will wear thin as a moth's wing. Doors will lean open that should stay shut. You will be asked to choose which one." Her riddle-smile deepened. "That is not the whole of it. The whole of it would not fit in your pocket." "Story of my life." Rory's breath caught as Isolde reached into the mother oak's root — into it, her hand sinking into the solid wood like a hand into water — and drew something out. It lay in the knot of the root like a splinter of moon that had been waiting. "Take the moon's tooth," Isolde said, and held it out. A dagger, slender and leaf-shaped, in a sheath of grey leather. When Rory drew it, the blade threw light of its own — faint, silver, faithful — and the cold of it bit through her glove and into her palm, colder than the December they'd left, cold as the space between stars. "Iron forgives," Isolde said. "Silver remembers. Moonsilver does neither. It will cut what is woven, and only what should be cut. My court made it before they exiled me — the last honest thing they ever made." Nyx had gone rigid beside her. "I knew a smith who worked moonsilver," they whispered. "That was before." "Then it remembers you too," said Isolde, which was not quite an answer, and turned away toward the pool. The dagger moved in Rory's hand, tilting, its faint glow leaning westward like a compass needle finding north. As they turned to go, it leaned harder, patiently, insistently, and the grove dimmed a courteous shade, showing them a different path than the one they'd come by. "Follow what gleams," Isolde said, without turning around. "The door out is never the door in." The crossing back was a held breath, a pop of cold, and then December slapped her like a bucket of water. Snow was falling. Fat, unhurried flakes, drifting through the black oaks, and the ground — Rory looked down and her stomach dropped — the ground wore a skin of fresh white, unbroken. Their inbound footprints were gone. The frost was gone. The moon had crawled halfway across the sky, and the deer were nowhere. Her phone was dead, a black mirror in her hand. "How long were we in there?" she asked. "Yes," said Nyx. Rory laughed — a short, unsteady sound that the snow seemed to eat — and slid the moonsilver dagger inside her coat, where its cold pressed against her ribs like a hand. Under the wool, faint and patient, it went on glowing, a thread of light the dark couldn't quite swallow, and at her throat the Heartstone lay quiet as a held breath, waiting for its door.
