The Blackwood School was more of a legend than a landmark. Hidden behind a veil of ancient, interlocking pines and a mist that never seemed to lift, it sat adjacent to Jess’s family home like a silent, stone giant. For seventeen years, Jess had stared at those woods from her bedroom window, watching the shadows dance between the trunks. She had been warned a thousand times by her grandmother never to cross the property line. "The woods have a memory," her grandmother would whisper, "and they don’t like to be disturbed."

But on this particular night, the woods weren’t just sitting there. They were calling.

It began at exactly midnight. A haunting, melodic howl ripped through the silence of the house, vibrating the glass in Jess’s window frame. It wasn't the high-pitched yip of a coyote or the lonely cry of a stray dog. This sound was deep, rhythmic, and felt almost like a human voice trying to sing through a throat of fur and bone.

Jess bolted upright, her heart hammering against her ribs. Usually, she was the type of girl who locked her door and hid under the covers at the first sign of trouble. But tonight, a strange, electric pull tugged at the center of her chest. It was an inexplicable magnetic force, dragging her toward the window, then toward the door.

"What is that?" she whispered to the empty room.

As if in response, the howl came again, louder this time. Without thinking, Jess grabbed a heavy metal flashlight from her nightstand and threw on a jacket. She didn't wake her parents; she felt as though she were moving in a trance, a puppet being guided by invisible strings.

As she stepped out onto the back porch, the cold night air bit at her cheeks, but she barely felt it. The "pull" was stronger now, a physical sensation like a hook in her heart, beckoning her toward the dark tree line. The woods felt alive. Every snap of a twig and rustle of a leaf sounded like a whisper.

She followed a trail she had never noticed before—a path of flattened ferns and silver-tipped moss that led deeper into the thicket than she had ever dared to go. The darkness was absolute, save for the narrow beam of her flashlight. Then, the trees suddenly peeled back, revealing an impossible sight.

A grand mansion stood in a clearing that had been empty just yesterday. It was a gothic masterpiece of grey stone, jagged gables, and stained-glass windows that shimmered like oil on water. It looked as though it had been plucked from a century-old photograph and dropped into the forest.

Jess gasped, her breath hitching in her throat. She took a step toward the iron-wrought gates, but the air behind her suddenly turned ice-cold.

"You’re early," a voice hissed.

Before Jess could turn, a figure materialized from the shadows. It was a man, though his movements were too fast for a human. He was a blur of movement and pale, hungry eyes. He caught her by the shoulder, and a sharp, searing heat exploded through her body as his teeth sank into her skin.

Jess screamed, swinging her heavy flashlight with every ounce of strength she had. It connected with the side of his head with a dull thud. For a split second, she saw his face—distorted, wild, and lupine—before he simply vanished into thin air, leaving behind nothing but the scent of pine and ozone.

Terrified and clutching her bleeding shoulder, Jess turned to run. But as she scrambled back toward the mansion, a glint in the dirt caught her eye. There, half-buried in the roots of an ancient oak, lay a diamond necklace. Its pendant was a massive, raw stone that pulsed with a faint, heartbeat-like light.

With the sound of heavy footsteps echoing from the mansion’s porch and a second howl rising from the trees, Jess scooped up the necklace and ran. She couldn't go back home—something told her the hunter was between her and the cottage. Spotting a narrow, ivy-covered opening in a nearby rock face, she dove inside.

Collapsing in the dirt of the small cave, Jess clutched the cold diamond to her chest. Her shoulder burned, her head throbbed, and as she drifted into an exhausted, feverish sleep, the last thing she heard was the sound of something large sniffing at the cave's entrance.

The cave was a cold, damp throat of stone that seemed to swallow Jess whole. She pressed her back against the jagged wall, her breath coming in shallow, jagged gasps that clouded in the freezing air. Outside, the world had gone deathly silent, a silence more terrifying than the howling. It was the silence of a predator waiting for its prey to make a mistake.

She looked down at her hand. Even in the gloom of the cave, the diamond necklace glowed with a rhythmic, ethereal light. It wasn't the steady shine of a gemstone; it pulsed, echoing the frantic beat of her own heart. The metal chain felt strangely warm now, almost as if it were trying to fuse with her skin.

Thump.

A heavy weight landed just outside the ivy curtain of the cave. Jess froze. She could hear the low, guttural breathing of something massive. A wet, sniffing sound drifted through the leaves. She squeezed her eyes shut, praying to a God she hadn't spoken to in years, clutching the necklace so hard the facets of the diamond dug into her palm.

"I know you're in there, little bird," a voice rasped. It wasn't the man from before. This voice was deeper, vibrating with a gravelly hunger that made the hair on Jess's arms stand up.

She didn't move. She didn't breathe. Her shoulder, where the man had bitten her, began to throb with a white-hot intensity. It wasn't just pain anymore; it felt like liquid fire was being pumped through her veins, moving from her shoulder toward her heart. Her vision began to swim, turning the dark cave into a swirl of shadows and silver sparks.

The heavy footsteps moved away, retreating toward the mansion, followed by a final, triumphant howl that seemed to signal the end of the hunt. But Jess couldn't celebrate. The fire in her blood was becoming unbearable. Her skin felt too tight, her bones felt heavy and soft at the same time, and a strange, metallic scent filled her nose—the scent of her own changing chemistry.

Exhaustion, heavy and unnatural, crashed over her like a tidal wave. The diamond in her hand flared one last time, a blinding burst of white light that filled the cave, and then the world went black.

When Jess's eyes finally flickered open, the damp smell of earth and moss was gone. She wasn't lying on cold stone; she was tucked under a heavy, silk-lined duvet. The air was warm and smelled faintly of old books, expensive cedarwood, and something sharp—like a thunderstorm about to break.

She bolted upright, her head spinning. She was in a room that looked like it belonged in a castle. The walls were lined with dark oak paneling, and a massive window looked out over a misty forest, but the glass was reinforced with thin silver bars.

"Where am I?" she whispered, her voice cracking.

She scrambled out of the bed, her legs feeling shaky and strangely long. She rushed to the door and grabbed the ornate brass handle. It didn't budge. She threw her weight against the wood, screaming for help, pounding until her knuckles were bruised.

"Let me out! Is anyone there? Please!"

No one answered. For an hour, Jess paced the room like a caged animal. She checked her shoulder, expecting to find a bloody mess, but instead, she found a faint, silver scar in the shape of a crescent moon. It didn't hurt anymore, but it felt... electric.

Suddenly, the heavy tumblers of the lock groaned. Clack. Clack. Click.

Jess's survival instinct kicked in. She didn't stand her ground; she dove under the high, four-poster bed, pulling the velvet dust ruffle down to hide her. She watched as a pair of polished black boots entered the room. They stopped just inches from her hiding spot.

"You can hide all you want, Jess," a calm, youthful voice said. "But you can't hide that scent. You smell like the woods... and you smell like the Stone."

A hand reached under the bed. Jess tried to scramble back, but the boy was too fast. He grabbed her ankle and gently, but with impossible strength, pulled her out into the light.
