The third child vanished on a night with no moon, and Alter Kindwood found her shoe at the edge of the black pines. He crouched over it. Blue flame guttered in the sockets of his deer skull. Moss shifted on his pale shoulders as he lifted the small leather thing and held it to the wind. The village would blame him again. They always did. They saw the antlers and the bone face and reached for their bows. He had spent two winters keeping their goats alive in secret, mending their snares, guiding lost hunters home through fog they never knew he cleared. None of it mattered if their children kept disappearing. If he could bring even one back, they might lower the arrows long enough to listen. He followed the shoe's scent past the last friendly tree. The deeper woods held something he did not know. He had felt it for a month now, a cold weight that pressed the sap back down inside the trunks. Wherever it walked, the vines on his arms curled tight and browned at the tips. He needed a name for it. Without a name, he could not fight it, and the next child taken would not be found at all. He stopped at a clearing where the moss had turned gray. On a low branch sat a bird carved from black stone, gold lines running along its wings. Its eyes were open and wet. It was not a carving. It watched him. He had heard the old trees whisper of such messengers, sent by the forest's first keepers to those who asked the right question. Alter knelt. "What took her." The stone bird opened its beak. The voice came from somewhere behind his skull, inside the bone. "The Hollow Man. He wore your shape once. He wears hunger now. He eats what is small and afraid, and he cannot cross running water while the sun is up." Alter's flames pulled low. He had suspected a beast. A beast he could track. This was worse and better at once. A thing with rules could be broken by its rules. "Where." "Under the split rock. Three children breathe there still. By dawn, two." The bird closed its beak and went back to stone. Alter picked it up. It weighed nothing. He tucked it against the necklaces at his chest and stood. He had his name and he had his clock. He also had a problem he had not counted on. To reach the split rock before dawn he would have to cross the creek at the village ford, in full view of the watchmen who had shot at him last spring. The girl's shoe was still in his hand. He closed his fingers around it and started toward the smell of woodsmoke and lanterns.

Alter reached the ford before the watchmen woke. Mist sat on the water. He crossed low, antlers wet, and the creek's cold ran through the vines on his arms. On the far bank he stopped. The split rock waited a mile north. Three children waited under it. He had a way in, but no way back. The creek that stopped the Hollow Man would stop the children too. They could not swim, and they would not let a bone-faced thing carry them. He crouched in the reeds and thought. His hands were empty. His arms were strong enough for one child, maybe two, never three, and never across running water while they screamed. Screaming would bring the watchmen. Watchmen would bring arrows. Arrows would leave the children in the woods with the Hollow Man returning at dusk. He needed something that carried them for him. Something they would follow without seeing his face. He took the stone bird from his necklaces. It had spoken once. He pressed his thumb to its beak. "I need a keeper," he said. "Not a messenger. A shape they will trust." The obsidian warmed. Gold lines along its wings brightened. It grew heavy in his palm, then heavier, until he set it on the moss and stepped back. The bird opened wide. Its wingspan doubled, then doubled again. Black feathers hardened into a low, hollow shell shaped like a boat, gold seams running along the ribs. An owl-shaped prow. Talons for a keel. It could hold three small bodies and float. Alter dragged the shell to the water. It sat on the current without sinking. He went north. He found the split rock and the crawlspace beneath it and the three children knotted together in the dark. He did not step inside. He set the girl's shoe at the opening and spoke through the crack in a voice he pulled up from the softest part of his chest. He told them a black owl waited by the creek to take them home. He told them not to look behind. He told them to run when he counted three. They ran. He followed at a distance, keeping his antlers below the ferns. At the bank the children saw the obsidian boat and climbed in without a sound. The current took them. Alter waded alongside, one hand on the gold seam, guiding the prow toward the village fires. He stopped where the reeds hid him. The boat drifted on toward the lanterns. A watchman shouted. Then a woman shouted, different, higher. Boots hit the shallows. Hands lifted the children out. Alter turned back into the trees before anyone looked upstream. The stone bird was gone. His clock was gone with it. The Hollow Man would wake at dusk and find the split rock empty, and he would come looking for whoever had emptied it.

Alter moved back through the pines while the sun climbed. The children were safe. The Hollow Man was not yet awake. Between now and dusk, he had one job: get a warning to the village without dying for it. If the villagers did not bar their gates before the light failed, the thing wearing his old face would walk in and take more children than three. He stopped at the ridge above the palisade. Red banners hung along the spiked wall. A severed head was stitched on each one. He had seen those banners aimed at his own back before. Any shape with antlers, they shot. Any voice from the trees, they answered with arrows. He could not walk to the gate. He could not shout from the treeline. He needed a mouth that was not his. He found the slime in the hollow below the ridge, squatting by a bush shaped like a skull, chewing its red leaves one at a time. Gorbov. Broad blue shoulders. A necklace of iron spikes. The one traveler the village tolerated because he sold them salt and never asked questions. Alter had watched him from cover for a season. He had never spoken to him. Alter stepped out where Gorbov could see him and stopped ten paces off, hands open. Gorbov froze mid-chew. His red eyes went to the antlers, then the flames in the skull, then the empty hands. "You're the thing they're screaming about," Gorbov said. His voice was low and flat, an island accent. "Down at the ford. All morning." "I brought their children back," Alter said. "There is another one. It looks like me. It will come at dusk. They have to close the gates before the sun touches the pines." Gorbov spat a red leaf. "And you want me to walk in and tell them a deer-skull said so." "They'll listen to you. They'll shoot me." Gorbov looked him over. Alter kept still. He had nothing to trade but the truth and the boat downriver. "The obsidian owl," Gorbov said. "On the bank. That yours?" "Yes." Gorbov grunted. He unhooked something from his belt pouch and tossed it into the moss between them. A circlet. Silver, gold curls, a teal stone at its center, made to sit between antlers. "Found it in a barrow last spring. Couldn't sell it. Wear it in." "They'll kill me." "They'll hesitate. That's a crown, not a trophy. Villagers know the difference. I'll walk in front. You stay ten steps back and don't speak." Alter lifted the circlet. It settled between his antlers and warmed against the bone. The teal gem caught the sun. Gorbov started down the slope toward the red banners. Alter followed at ten steps, antlers high, hands empty, walking into the range of every bow on the wall.

They came out of the pines together. Gorbov walked first, hands raised, calling ahead in his flat island voice. Alter followed at ten steps, the silver circlet warm between his antlers, the teal stone catching sun. Bows lifted along the palisade. Red banners with their stitched heads shifted in the wind. No arrow flew yet. The crown was doing its small work. A voice on the wall shouted for them to stop at the gate line. Gorbov stopped. Alter stopped. The gate creaked open a hand's width. A blacksmith stepped out, thick arms bare, a mohawk the color of his skin, a braided beard laid over a round belly. He carried a hammer, not a bow. Behind him, six spears leveled at Alter's chest. "He says a thing wearing his face comes at dusk," Gorbov said. "He says close the gates." The blacksmith spat. "He says. A skull with fire in it says." He looked at Alter. "You brought our children back this morning. In a stone boat." "Yes," Alter said. "Prove it was you. Not a trick to open our gates at sundown." Alter had no proof. He had no token from the children, no words only they would know. He had brought them in silence and left in silence. The spears shifted. The light on the ridge was already tilting. He knelt in the dirt. He set both hands flat on the ground between him and the gate. He thought of the stone bird, of the owl-boat on the bank. He asked the wood to come. The ground moved. Branches pushed up through the grass at the gate line, thin at first, then thick, twisting into each other. They wove as they grew, layer over layer, a fence of living wood rising in a curve across the open gate. In four breaths it stood taller than the blacksmith. The spears drew back. Someone on the wall swore. "Close your gate behind this," Alter said. "When the light touches the pines, do not open it for anything with my face. Not for my voice. Not for a child's voice. Nothing crosses this wood until dawn." The blacksmith laid a hand on the woven branches. He pushed. It held. He looked at Alter a long moment. "Get back in the trees," he said. "If you're still standing there when the sun drops, my men will shoot you anyway." Gorbov stepped through a gap that closed behind him. The main gate slammed. Bars fell into place. Along the wall, bows turned outward now, not down. Alter walked back up the ridge. The circlet cooled against his bone. He had bought them the night. He had also told the Hollow Man exactly which wall to test, and left himself outside it, alone, wearing a crown that shone.

Alter climbed the ridge above the settlement and kept walking. The circlet cooled on his skull. His legs would not. Growing the fence had pulled something from the marrow. Every step felt like wading. The blue flames in his eye sockets guttered low. He needed water, or moss, or sleep, and the sun was already sliding toward the pines. If the Hollow Man came now, Alter could not lift a hand against it. He followed the sound of water. A creek bent north into stone, then dropped. He pushed through wet ferns and saw it: a tall split waterfall, two curtains parted around a hollow in the rock. Light glowed inside the gap, warm as a banked fire. He stepped through the spray. The falling water shut behind him like a door. The cave opened wider than it had looked. A shallow pool sat in the center, ringed by carved stone, gold specks drifting above the surface like slow sparks. The far wall glittered with clusters of blue crystal and small pink flowers pushing through the rock. Alter smelled green things growing where no sun reached. He knelt at the pool's rim. He did not know if he could drink it. He was too tired to care. "Not that one, love. That one's for looking." The voice came from above. A fairy hovered near the crystals, no taller than his forearm, pink wings beating slow. White hair, white dress, a face that did not flinch at his skull. She was the first living thing in weeks that had not reached for a weapon at the sight of him. "Seraphina Moonpetal," she said. "You're leaking, antler-boy. Sit before you fall in." He sat. She flew a circle around his head and clicked her tongue at the circlet. "Village iron. That's draining you too. Take it off in here." He lifted the circlet from his antlers. The room brightened at once, or he did. She landed on the pool's edge and dragged her palm across the water. The gold sparks gathered under her hand and rose in a sheet. They stretched, thinned, wove themselves into cloth. A cape of dark sky and scattered stars settled over his shoulders. It weighed nothing. Warmth ran down his spine into his hands. "Borrowed, not given," she said. "It carries what the pool holds. Enough for one fight. After that it's just pretty." Alter flexed his fingers. The blue flames in his sockets steadied and grew. He felt the wood in his bones answer again. "The thing wearing my face is at the village wall by now," he said. "Then don't sit chatting." He stood without effort. He set the silver circlet back between his antlers. He stepped out through the falling water into the last of the light. The pines below were already dark. Somewhere past them, something was testing a fence he had grown.

Alter came down the ridge at a run. The star-cape pulled him faster than his legs alone could carry. Below, the village sat inside its spiked palisade, red banners hanging still in the dusk. Something tall and pale paced the outside of his wooden fence. It wore his shape. It struck the fence with an open hand and the wood shuddered. Alter stopped in the pines. He counted what he had. One cape, burning down like a candle. One creature stronger than him. A village behind sealed gates that would shoot him on sight. If he fought alone, the cape would empty before the Hollow Man fell. He needed hands beside him. He had no way to call for them. A wet slap sounded behind him. Gorbov pushed through the ferns, broad blue shoulders scraping bark, the spiked necklace bouncing on his chest. The merchant had come back. Alter felt something in his ribs loosen at the sight. "Saw the thing at the wall," Gorbov said. "Thought you might be dead already." "They won't open the gate for me," Alter said. "They will for you. Tell them the fence-grower is here. Tell them to bring iron and fire to the north wall. Tell them the thing at their gate is not me." Gorbov looked at the cape, then at the Hollow Man. "They'll shoot me too." "Show them the circlet you gave me. Say I sent it back as proof." Alter lifted the silver circlet from his antlers. His skull felt lighter and heavier at once. He pressed the circlet into Gorbov's wet palm. Then he reached into his cape and drew out the stone bird. In his hands it stretched and hardened into a black obsidian owl, gold lines running along its wings. Not a boat this time. A signal. "When you reach the wall, set this on the gatepost," Alter said. "I'll light it from the trees. They'll see where to come." Gorbov took the owl under one thick arm and ran for the settlement path. Alter climbed a pine and waited. He watched the Hollow Man rip a slat from the fence. Gorbov reached the gate. He held up the circlet and shouted. The gate cracked open. The owl went up on the post. Alter opened his hand toward it. A thread of cape-light left his chest and struck the obsidian. The owl blazed gold. Every window in the village turned toward it. Men came out with torches and iron pikes. The blacksmith led them, mohawk lit red by the fire he carried. They saw the pale thing at the north fence and understood. Alter dropped from the pine and ran to meet them. The cape burned brighter. His strength held. For the first time, he was not alone in the dark. The Hollow Man turned from the fence and saw them coming.
