The frost did not just creep across the stone floors of Ironspike Keep; it claimed them like an invading army.
Posy Hale stood at the long wooden trestle table in the lower dispensary, her fingers numb inside her fingerless wool gloves. The small iron stove in the corner was cold. Garrow had promised her three dry logs by midday, but the midday sun had never arrived, swallowed by the thick, charcoal-grey clouds that sat on the mountain like a heavy lid.
The water in her clay washing basin had frozen solid. A thick, opaque disc of ice stared up at her, trapping a few stray lavender buds beneath its surface like ancient insects in amber.
She picked up a small iron chisel and tapped the center of the ice. The sharp, metallic ring of the tool echoed off the vaulted ceiling, a lonely, hollow sound that made her shoulders tense. With a hard grunt, she drove the chisel down, shattering the ice into a dozen jagged shards. She lifted a piece, pressed it to her dry, cracked lips, and let the freezing water melt down her parched throat.
It was a temporary relief. Her throat felt as though it were lined with sand, and her lungs burned with every breath she took of the stagnant, freezing air.
The Keep had become a silent tomb of the living.
Over the last forty-eight hours, the pale-shrapnel fever had taken a turn for the worse. The early, shivering stage had passed, replaced by the deep, rattling congestion that turned a wolf’s blood to sludge. From the corridors above, she could hear the rhythmic, wet coughing—a constant, dragging chorus that never seemed to stop. It was the sound of fifty pairs of lungs slowly filling with their own fluids.
She filled a wooden tray with small clay cups of her willow-bark tea. It was cold, but it was all she had. She had used the last of her dry firewood to boil the mixture the night before, and now she was reduced to serving the bitter medicine frozen or slushy.
"You look like a ghost, midwife."
Posy turned to see Garrow entering the room. The old steward was clinging to the heavy iron ring of the doorframe, his knuckles white and trembling. His usually neat grey beard was matted with dried sweat, and the skin around his eyes had turned a deep, bruised purple. He was breathing through his mouth, each inhalation accompanied by a high, whistling rattle that made Posy’s medical instincts scream.
"You should not be standing, Garrow," Posy said, her voice flat and steady as she picked up the heavy tray. "Go back to your cot in the hall."
"The wood-sheds are empty," Garrow whispered, ignoring her advice. He leaned his weight against the stone wall, his chest heaving. "The young men tried to break the ice off the reserve stacks by the outer wall, but the timber is frozen together like a single block of stone. We cannot split it. Without fire, the sick will not survive the night. The cold is dropping into the lower wards now."
Posy set the tray down with a sharp clatter. "Then we must use the furniture. Break the benches in the great hall. Tear down the oak tables. Burn the decorative shields if you have to."
Garrow let out a dry, hacking laugh that ended in a wet cough. He spat a dark, metallic-smelling glob into the straw at his feet. "Burn the High Table? The elders would sooner freeze. That wood was carved from the first heart-tree the founders felled three hundred years ago. It is sacred."
"A piece of dead oak is not sacred, Garrow," Posy snapped, stepping closer to him, her dark eyes flashing with an irritation she was too tired to hide. "The lives of your people are. If your Alpha returns to a hall filled with thirty frozen corpses and a pristine High Table, do you think he will praise your devotion to historical furniture?"
Garrow’s jaw tightened, his grey eyebrows drawing together in a fierce scowl. For a second, the old warrior's authority flared in his chest, but the fever quickly snuffed it out. He slumped back against the wall, his head hanging low. "He will not return. The Shatter-Frost has never been conquered. Not even by an Alpha of the Ironspike line. He is dead in the drifts, human. And we are just waiting for our turn to follow him."
"He is not dead," Posy said.
She did not say it out of loyalty to a man she had never met. She said it because she had felt him.
Ever since the night she had delivered the baby, she had felt a strange, phantom pressure in the back of her mind—a distant, heavy thrumming that felt like the vibration of a great iron bell. It was the pack-bond. Even though she was human, even though she possessed no wolf of her own, her secret magic had acted like a lightning rod, catching the residual currents of the bond when Julianne died. She knew, with a quiet, terrifying certainty, that the Alpha’s thread had not snapped. It was still there, pulling against the frozen distance, dragging itself toward the Keep with the slow, unstoppable force of a glacier.
But she could not tell Garrow that. If she admitted she could feel the bond, they would know she was more than a traveling midwife. They would start asking questions she could not answer.
"Go to the hall," Posy ordered, her tone softening just enough to show she was not entirely heartless. "Tell the young ones to break the smaller benches. Leave the High Table for now if it preserves your pride, but get me wood. I need to boil more lungwort before the sun goes down."
Garrow hesitated, then gave a single, stiff nod. He turned and shuffled back down the dark corridor, his boots dragging against the frost-covered stone.
Posy picked up her tray of cold tea and made her way toward the great hall.
The scene that greeted her was a nightmare of sweat and ice. The vast room, designed to host hundreds of feasting warriors, had been converted into a massive sick bay. Dozens of wooden cots were crammed together in neat rows, their occupants huddled under piles of heavy wolf-skins. The heat from so many feverish bodies had risen to the high rafters, melting the frost on the cedar beams and causing a steady, freezing condensation to drip down on the sick below.
It was like a slow, grey rain inside the castle.
Posy walked between the rows, her boots splashing in the shallow puddles of melted frost. She knelt beside a young wolf girl, no older than twenty, whose face was completely covered in the pale, raised pustules of the fever.
"Drink this, Cora," Posy said, lifting the girl's head with one strong hand while holding a clay cup to her blue lips.
Cora groaned, her eyes rolling back in her head as she took a small, hesitant sip of the cold willow-bark tea. She immediately coughed, spitting the bitter liquid back out over Posy’s woolen sleeve. "It is too cold," the girl wept, her voice a tiny, childlike squeak. "It feels like ice in my chest, midwife. Please... I want my mother."
"Your mother is resting, Cora," Posy said gently, wiping the girl’s chin with a clean cloth. "You must keep the tea down. It is the only thing that will keep your blood moving."
She moved to the next cot, and then the next.
By the time she reached the end of the third row, her tray was empty, but her heart was heavier than ever. The medicine was not working fast enough. Without heat, without a proper fire to sweat the fever out of their bones, her herbs were nothing more than a temporary shield against the dark.
"She is hoarding the green-root!"
The voice was loud, sharp, and dripping with venom.
Posy did not need to turn to know who it was. Martha, the oldest of the pack’s elder matrons, was standing at the entrance of the hall, her arms crossed over her thick, fur-trimmed chest. Her sharp, pale face was twisted in an expression of deep suspicion, her cold blue eyes fixing on Posy like a hawk targeting a field mouse.
"I have no green-root, Martha," Posy said, turning slowly to face the older woman. "The root grows only in the western valley, which is currently buried under ten feet of ice. I am using willow bark and dried lungwort from my own packs."
"You lie," Martha said, her voice carrying through the quiet, groaning hall, drawing the attention of those few wolves who were still conscious. "Brenda saw you. She saw you in the nursery two nights ago. She said you used some dark, forbidden trick to feed the heir. She said you made her swear an oath of silence."
Posy’s blood ran cold.
She kept her face completely blank, her years of training as a midwife hiding the sudden, violent thrumming of her heart. She had known Brenda could not keep the secret forever. A wolf’s loyalty to her elders was a powerful thing, especially when the fear of death was pressing down on them.
"Brenda was delirious with the fever," Posy said, her voice dropping into a cool, professional register. "She has the shrapnel-spots on her chest. Her mind is playing tricks on her, just as yours is if you think I have some secret supply of medicine hidden in my skirt."
"The heir is thriving while our own children are dying in the straw!" Martha declared, stepping forward, her heavy leather boots clicking loudly on the stone. "How is it that a premature pup, born to a dying mother in a freezing room, is growing stronger by the hour? He does not have the fever. He does not even shiver. You are doing something to him, human. You are using some southern witchcraft to steal the life-force of this pack and give it to the boy!"
The accusation was so ridiculous, yet so close to the truth, that Posy felt a cold sweat break out along her collarbone.
She did not use witchcraft to steal life. She used her own life-force to save the child. But to these desperate, superstitious wolves, there was no difference. If they discovered the truth of her green-blood, they would not see her as a savior; they would see her as a monster, or worse, a valuable tool to be locked in a cellar and drained of her power.
"The boy is strong because his mother’s wolf gave him her final breath," Posy said, her voice rising to meet Martha’s challenge. "He is strong because he is the Alpha's son. If you want to accuse me of witchcraft because I have kept your heir alive while you sat in your chambers praying to dead spirits, then do it. But do it while you carry these wooden trays yourself. Because if you lock me up, Martha, there is no one else in this Keep who knows how to keep these lungs from bursting."
Martha’s eyes narrowed into tiny slits, her upper lip curling back to reveal her long, yellowed fangs. She stepped closer, her scent of stale lavender and old sweat filling Posy’s nose. "You think you are indispensable, flat-foot. But you are just a tool we hired to catch a pup. When Branen returns—if he returns—he will see what you have done. He will see how you have poisoned his house with your human tricks."
"I welcome his return," Posy said, her tone deadpan. "Perhaps he will bring some common sense with him. It seems to be in short supply in this castle."
She did not wait for Martha’s response. She turned her back on the elder matron and walked out of the hall, her head held high, though her legs felt like lead.
She climbed the spiral staircase toward the east wing, her breath coming in short, painful gasps. The air grew colder with every step she took, the wind howling through the high arrow-slits like a pack of wolves contesting a kill.
When she reached her small chamber adjoining the nursery, she pushed the door shut and slid the heavy oak bolt into place.
The room was freezing, but it was safe.
She walked over to the small, cedar-wood cradle that sat beside her narrow cot. Inside, wrapped in three layers of thick wool and flannel, lay the baby.
He was sleeping. His tiny, perfectly formed face was relaxed, his cheeks a healthy, dusky pink. His breathing was fast and even, completely free of the rattling congestion that plagued the rest of the Keep.
As Posy approached, the boy’s eyes fluttered open. They were a deep, dark grey—the color of a stormy sea—and they fixed on her with a strange, solemn intensity that seemed far too old for a two-day-old child.
"Hello, little wolf," Posy whispered, her voice dropping into the quiet, warm register she reserved only for him.
She reached into her apron pocket and pulled out her mother's empty brass locket. She held it up, letting the weak, grey light from the frosted window catch the scratched metal.
She had kept this locket empty for ten years because it was her promise to herself. It was the physical reminder that she belonged to no one, that she owed nothing to any pack, and that her heart was her own.
But as she looked at the child, she felt the first cracks appearing in that armor.
She had fed him again that morning. The process had left her so weak she had nearly fainted on the stairs. The green-blood magic within her was not an infinite well; it was a physical resource, a part of her own vitality. Every drop of the warm, golden milk she forced her body to produce was a drop of her own life-force, transferred directly into his veins.
She was binding herself to him, thread by thread, drop by drop.
"I cannot keep doing this," she whispered to the empty room, her voice trembling. "If I give you everything, there will be nothing left of me to run with."
She sat down on the edge of the cot and pulled the baby into her lap. He instantly began to wriggle, his tiny, blunt fingers reaching out to clutch at her collarbone.
She looked at her hands. The skin across her knuckles was split and bleeding, the red gashes raw from the freezing water and the harsh lye soap she used to clean the dispensary. They hurt with a constant, throbbing ache that made it difficult to grip her medical tools.
Posy closed her eyes.
She reached down, deep into the locked cellar of her heart, and found that tiny, dormant spark of green magic.
She had kept it hidden for so long, using it only in the dark, only when the risk of discovery was zero. It was her secret comfort, the only part of her mother she had left, the only thing that made her feel connected to the earth when she was trapped in these cold, stone cages.
She drew on the spark.
A soft, golden-green warmth began to hum in the center of her palms. It was a gentle, quiet light, like the sun shining through a young birch leaf in the spring.
She pressed her palms together.
The raw, bleeding cracks on her knuckles began to close. The torn skin knit itself back together with a soft, tingling sensation, leaving only faint, silver lines where the gashes had been. The throbbing pain vanished, replaced by a deep, comfortable warmth that radiated up her arms and into her chest.
It was a small healing. A simple thing.
But as the green light faded back into her skin, Posy felt the hollow, aching void in her chest grow just a little wider.
She was completely isolated. The storm had locked the gates. The pack was dying around her, their hatred and suspicion of her growing with every body they carried to the lower cellar. Her only comfort was a magic she could never show, a power she had to keep locked away like the empty locket around her neck, lest it become the very cage that trapped her forever.
She pulled the baby closer to her chest, her lips pressing against his soft, dark hair.
"We have to get out of here," she whispered into the dark. "Both of us. Before they find out what we are."
The wind answered her with another violent scream against the stone, and the baby gave a small, quiet sigh, his tiny hand clenching tightly around the empty brass locket that lay between them.
