Parker Winterbloom wanted to be a ranger. Not someday. Now. This morning he had walked to the ranger station and told the rangers he could speak to every animal on Blinding Summit. They laughed. The oldest one crouched down and said, "Son, you've never spent one night out there alone. Come back when you've survived the tundra." Then they shut the door. Parker walked home through the snow with his jaw tight. He was ten. He had blonde hair and blue eyes and warm boots, and he understood the tundra better than any grown man. But understanding was not proof. He needed proof. At the homestead, warm light glowed in the windows. Inside, purple leaves brushed the greenhouse glass, and sap dripped from the tall trees his family grew for medicine. His father knelt by the fireplace, splitting kindling. His father was a big man, quick to laugh, and he had taught Parker every knot and track and edible root. "They won't take me," Parker said. "They want me to survive a night out there alone." His father set down the axe. He didn't laugh this time. "Then you'll do it," he said. "But not because I say so. Because you're ready." He handed Parker a small knife and one match. "That's all. Prove it to yourself first." Parker's mother watched from the greenhouse. She was strong and calm, and she nurtured every sick fox and hare that wandered near. She wanted to argue. Parker saw it in her face. Instead she wrapped bread in cloth and pressed it into his hands. "Listen to the animals," she said. "They'll tell you when a storm turns." Parker hiked out before dusk. Wind cut across the open snow. He found a hollow beneath a rock ledge and started clearing it. A ptarmigan chattered from a drift. "Weather's coming," it said. "Fast." Parker asked how fast. The bird flicked its wings toward the west. "Before dark." He worked quicker. He packed snow into a wall, cut spruce boughs for a floor, and struck his one match under dry moss. The flame caught. He fed it twigs until it held. The storm hit hard. Snow roared past his shelter, but the wall blocked the worst of it. Parker sat by his small fire, chewing bread, listening to the wind. A fox pushed into the hollow and curled beside him, shivering. Parker shared his warmth. All night they kept each other alive. At dawn the sky cleared. Parker walked straight to the ranger station, cold and grinning. He described the storm, the shelter, the fox. The old ranger studied him a long time. "You really made it through that," the ranger said. It was not a question anymore. "I did," Parker said. "Alone." The ranger nodded slowly. "Then I can't turn you away for being young." He reached behind the desk and pulled out a form. "But surviving a night isn't the same as being sworn in. There's a trial. And no one your age has ever passed it."

The trial form sat folded in Parker's coat pocket. He walked the packed snow path toward the little ranger station, saying the words in his head. He was ready. Then he heard it. A high, broken cry cut across the wind, off to his left. He stopped. It came again, weaker. Parker followed the sound to a snarl of frozen brush. A snowshoe hare lay on its side, one hind leg pinned in an old wire snare. Blood darkened the snow. The hare thrashed and screamed. Parker knelt and spoke to it low, in its own quick language. "Hold still. I'm here to help." The hare stopped kicking and stared at him, chest heaving. Parker glanced back toward the station. The trial started soon. If he stayed, he might miss it. If he left the hare, the wire would cut deeper, and a fox would find it before dark. A ranger did not walk past a dying animal. That was the whole point of being one. He pulled his small knife and started sawing the wire. The strands were rusted and tight. Parker worked slow so he would not cut the leg. "Almost," he told the hare. "Almost." The wire snapped. The hare pulled free and lay panting. The leg was hurt but not broken. Parker bound it with a strip torn from his scarf, the way his mother bound the animals she nursed. "You lose things out here when you rush." The voice was rough and close. Parker turned. Ranger Randy stood over him, gray beard stiff with frost, hat low against the wind. He was the oldest ranger, the one who watched the park longer than anyone. He had seen Parker's gift before and believed it. His face gave away nothing. "It was caught," Parker said. "I couldn't leave it." Randy crouched. He studied the snapped wire, then the hare's bound leg. He touched the snare with one finger. "This isn't ours," he said. "We don't set wire here. Haven't for years." His voice dropped, slow and careful. "I don't say this often. Something's wrong in my park. Animals hurt where nothing should hurt them." Parker looked at the rusted wire again. "Then there's more of these." "Maybe." Randy stood and lifted the hare gently into his coat. "You missed your trial time, boy. Bell rang ten minutes ago." Parker's stomach dropped. The form in his pocket felt useless now. "I know." Randy watched him a long moment. "You chose the animal over the door." A short nod. "That's the answer most men fail." He turned toward the station. "Come on. I'll speak for you. But the trial waits for another day now. And I need eyes I trust while I find who's laying wire." Parker rose, cold and shaking, and followed. He had lost his chance to be sworn in today. He had gained something heavier instead.

Three days after Randy took the hare, Parker found another animal in the wire. A young fox lay in the snow, one paw torn where the snare had bitten deep. It did not thrash. It watched him with dull eyes. Parker knelt and spoke in the fox's language, soft and low. "I know you. You kept me warm in the storm." The fox's ear twitched. Parker cut the wire fast and gathered the fox into his coat. The paw bled through the cloth. The fox was too weak to run and too hurt to hunt. It would die out here alone. Parker turned toward home and walked fast. The homestead glowed ahead, windows warm against the white dusk. Parker pushed through the door. Heat from the great fireplace hit his face. "Mom!" he called. "It's hurt bad." Margaret came from the greenhouse, hands still dark with soil. She saw the blood and set aside her trowel. "Table," she said. She spread a clean cloth. Parker laid the fox down. Margaret lifted the torn paw and studied it. She did not flinch. "Deep. Not to the bone." She pressed cloth to the wound. "Boil water. Bring the jar of green salve." Parker obeyed. Margaret cleaned the paw, packed it with salve, and wrapped it tight. The fox lay still under her steady hands. "It'll keep the paw," she said. "If the wound stays clean." She looked at Parker. "That's your job now." Daniel came in from the cold, stamping snow off his boots. He saw the fox and raised an eyebrow. "Another guest. At this rate we'll need a bigger table." He crossed the room and crouched by the fox. His grin faded when he saw the wound. "Same wire?" "Same wire," Parker said. "There's more of them out there." Daniel nodded slow. He picked up the cut snare Parker had dropped and turned it in his fingers. "Then you need to learn something. Freeing them one at a time won't stop the man setting these." He held the wire to the firelight. "Look here. See the twist? Every trapper ties his own knot. Same hands, same twist, every time." Parker leaned close. The wire ends crossed in a tight double loop. "Find that same knot on the next snare," Daniel said, "and the one after, and you can track the man who ties it. A snare is a signature." He set the wire in Parker's palm. "You want to be a ranger? A ranger doesn't just save the animal. He catches who hurt it." The fox lifted its head and looked at Parker. Parker closed his hand around the wire. The fox would live. But now he held a clue, and a colder truth. Somewhere in the park, one person kept tying the same knot. Parker would learn to read it.

The next morning, the fox slept by the fire with its wrapped paw. Parker packed his knife and a coil of string. His father Daniel waited at the door, grinning under his beard. "You found one knot," Daniel said. "Now let's see how many the man tied. Bring your ears, boy. All of them." They walked out into the white tundra. Snow crunched under their boots. Parker led the way toward the tall trees with purple leaves. Sap dripped from their high branches in slow violet lines. A pair of gray birds huddled in the lowest fork. Parker stopped below them. He whistled soft, then spoke in their clicking tongue. "Where does the wire hide?" The birds fluffed their feathers. One pointed with its beak, past the trees, toward a low ridge. Parker turned to his father. "They've seen it. This way." Daniel raised both eyebrows. "I've hunted these woods thirty years. Never once got directions from a bird." He shook his head and followed. Under the ridge, Parker found the first snare. Wire looped tight around a stake. He knelt and studied the ends. A double loop, crossed and pulled. "Same knot," he said. His father crouched beside him and looked close. "Same hands," Daniel agreed. "Cut it. Leave the stake so we remember the spot." They moved on. A hare thumped from a burrow and Parker spoke to it low. It led them to a second snare hidden under brush. Then a fox barked from a rise and showed them a third. Each time Parker checked the wire. Each time the ends crossed in the same double loop. His father counted them on his fingers. By midday they had found six. Six snares, six matching knots, all in a line that pointed north along the ridge. Daniel wiped his brow and looked at his son with something new in his eyes. "You talked us straight to every one," he said. "I doubted it, Parker. I won't again." Parker held the last cut wire in his glove. He turned it toward the pale sun. The double loop was clear now, burned into his memory. He knew this knot like a face. "They all point one way," he said. "The traps get newer as we go north. He's still setting them." Daniel stood and looked up the ridge. His grin was gone. "Then he's close. Maybe today close." He put a hand on Parker's shoulder. "You wanted to catch him. Now you can read his trail. That's ranger work, son." Parker looped the six wires onto his belt. He had his proof and his direction. Somewhere up that northern ridge, a man knelt in the snow tying the same knot again. Parker knew the animals would tell him where. He looked north and started walking, and his father followed him this time.

The snare line pointed north, into a stretch of ridge Parker had never crossed. He stopped at the edge of the last snow field. Ahead the ground broke into cracks and ice shelves. One wrong step meant a fall. "I don't know this ground," Parker said. "If we pick wrong, we lose his trail." Daniel crouched and studied the slope. "Cliffs on the left. Thin ice on the right. Bad choices both ways." Boots crunched behind them. Parker turned. Ranger Randy came down the ridge, older and gray-bearded, the same man who had once watched Parker tell a coyote to sit and stay. Randy had seen the gift was real. Now he studied the boy's belt, heavy with cut wire. "Six snares," Randy said. "Same knot?" Parker nodded. Randy's jaw went tight. "I don't say this often. That man's hurting my park. You found more than I did." "The trail goes north," Parker said. "But I've never crossed this. I can't read the safe way." Randy looked at the broken ice and shook his head. "Neither can I from here. Been years since I climbed it." Daniel wiped frost from his beard. "Then we're stuck. Guess wrong and the boy falls." A soft rustle came from the low brush. A small creature hopped out, its body round like a rabbit crossed with a guinea pig. Bright pink and blue hair ran down its neck. It sat in the snow and watched Parker with wide purple eyes. Parker knelt slow. He made a low chirping sound, the creature's own tongue. "You live up here," he said. "Which way holds?" The creature's ears twitched. It hopped three steps left, then stopped and looked back. Parker followed on his knees. The little animal wove between two ice shelves, past a crack Parker had nearly stepped into, and up onto solid rock. Every place it set its paws, the ground held firm. "It knows the route," Parker said. "It crosses this every day." Randy watched the creature lead and lowered his hat brim. "Never seen the like," he muttered. Daniel tested the first ice shelf with his boot. It held. "The thing's picking safe ground," he said. "Follow the fur ball, boy." They climbed slow, one careful step at a time, the small creature always three hops ahead. Twice it darted around a hidden gap that would have swallowed a leg. Parker marked each turn in his memory. They reached the top of the ridge. The creature stopped, sniffed the wind, and vanished into a burrow. Parker stood and looked north. The land opened flat before him. And there, pressed fresh into the snow, ran a line of boot prints. Beside them lay a coil of wire and a stake, half driven. "He was here," Parker said. "This morning." Daniel put a hand on his shoulder. Randy stepped past both of them, eyes hard on the tracks. "Then we don't stop," Randy said. "He's close."
