FROSTBITTEN HEARTS

The cold never bothered me.

That was a lie. The cold bothered everyone in the Scandinavian wilderness, even the wolves. Especially the half-bloods like me. But tonight, the cold was my ally. It kept the patrols inside their warm dens. It numbed the guilt in my chest. It made the snow crunch under my paws in a rhythm that almost sounded like a heartbeat.

My heartbeat.

I ran.

The forest was a cathedral of white and shadow, the moon hanging low and heavy like a silver coin behind the frostbitten pines. My wolf form was leaner than the others—smaller, faster, with fur the color of dirty cream rather than the proud blacks and grays of the European Pack. They called me Half-Blood like it was my name. The Luna who shouldn't exist.

But Kael had chosen me. And Kael's word was law.

Tonight, however, I wasn't thinking about Kael. Or the pack. Or the way the elders looked at me like I was a stain on their perfect lineage. Tonight, I was hunting. A lone elk had wandered into our territory, injured and slow. One kill. That was all I needed. One kill to prove I was still useful. Still worthy.

The scent hit me when I crested the ridge.

Blood.

But not elk blood. Wolf blood.

My paws dug into the snow, halting my momentum. The wind shifted, carrying the metallic tang straight into my nostrils, and beneath it—something darker. Something ancient. The hair on my spine rose, and a growl rumbled low in my throat. Stranger. Dying. Close.

Every instinct screamed at me to run back to the den. To fetch Kael. To let the Alpha handle whatever had crawled onto our land. But I was the Luna, even if half the pack didn't accept it. And a Luna didn't abandon a wounded creature to freeze alone in the dark.

Stupid. Sentimental. Half-blood.

I found him at the base of a frozen waterfall.

The wolf was massive—easily the size of Kael, maybe larger. His fur was a deep, reddish brown, like rust or dried blood, matted with fresh crimson that steamed in the frigid air. His side was torn open, a gash so deep I could see the white glint of rib beneath. He wasn't moving. His chest barely rose.

But he was alive. Just barely.

I shifted back to my human form, the change rippling through my bones like ice water. It was faster than most wolves' shifts, another half-blood trait they sneered at. My bare feet hit the snow, and I ignored the bite of the cold. Naked, shivering, I knelt beside the dying wolf and pressed my hands to his wound.

"Easy," I whispered, though he couldn't hear me. "Easy. I've got you."

Healing wasn't a gift I'd been born with. It was something I'd learned—watching the pack healers, reading the old texts in Kael's library, practicing on injured rabbits and birds. Half-bloods had to be useful. Half-bloods had to earn their place.

I closed my eyes and focused. The warmth started in my chest, a dull ache that spread down my arms and into my palms. It wasn't much. It would never be enough to fully heal a wound like this. But maybe—just maybe—it would stop the bleeding. Buy him time.

Minutes passed. Or hours. Time had no meaning in the frozen dark. The wolf's breathing steadied beneath my hands, and the gash began to knit, slowly, imperfectly, like a clumsy stitch. I was trembling now, exhaustion pulling at my bones. The warmth in my chest had become a cold burn.

Then the wolf moved.

Not a twitch. A shift.

The transformation was agonizing to watch. Bones cracked and re-formed. Fur receded into skin. The massive body contracted, folded, reshaped itself into something smaller, more human. I scrambled backward, my heart slamming against my ribs, and watched as a man emerged from the wolf's remains.

He was beautiful. That was the first thought that cut through my terror. High cheekbones, sharp jaw, skin tanned like he'd spent centuries in a sun I'd never known. His hair was dark, almost black, matted with blood and snow. His body was a roadmap of old scars—some from claws, some from blades, some from things I couldn't name.

And his eyes.

When they opened, they weren't wolf-gold or human-brown. They were silver. Bright. Ancient. Hungry.

They locked onto mine, and I couldn't breathe.

"Well, well," he said, his voice a low rasp like stones grinding together. A slow smile spread across his face, bloodstained and wolfish. "A half-blood Luna. And here I thought the European Pack had lost its nerve."

I knew that voice.

No. Not possible. He was dead. He'd been dead for fifteen years. The entire wolf world had mourned him, told stories about him, whispered his name like a prayer and a curse.

"Darius," I breathed.

The legendary Alpha of the American Pack. The one who'd disappeared during the Great War. The one who'd been hunted by every s—the one who'd supposedly died in a fire, taking a hundred enemies with him.

He was very much alive. And he was lying naked in the snow, looking at me like I was dinner.

"You know me," he said, still smiling. "Good. That saves time." He pushed himself up onto his elbows, wincing as his wound pulled. "You saved my life, little half-blood. Do you know what that means?"

I shook my head, backing away another step. My hand found a rock beneath the snow, cold and sharp. Not a weapon. A reassurance.

"It means I owe you," Darius continued. "And I always pay my debts." His silver eyes glittered. "But first—" He pushed himself to his feet, swaying but steady. Naked. Unashamed. Every inch the Alpha he'd been born to be. "First, you should know what they're not telling you."

"Who?"

"Your Alpha. Your pack. Everyone who's ever looked at you like you were less than dirt." He took a step toward me, and I held my ground even though every nerve screamed at me to run. "You're not just a half-blood, Elara. You're something much more dangerous."

I didn't tell him my name. I'd never told him my name.

"How do you know who I am?" My voice came out steadier than I felt.

Darius laughed, a low, rough sound that echoed off the frozen waterfall. "Everyone knows who you are, little Luna. The half-blood who warmed an Alpha's bed. The mongrel who sits on a throne of pure blood. The girl who carries a secret in her veins that could tear the three packs apart." He was close enough now that I could smell him beneath the blood—smoke and pine and something older, something wild. "Kael didn't tell you, did he? About your mother? About where you really came from?"

My mother was dead. She'd died giving birth to me, a half-blood with no father, no lineage, no place in any pack. That's what Kael had told me. That's what I'd believed my entire life.

"Shut up," I whispered.

"He's using you." Darius's voice softened, almost gentle. "They're all using you. The mark on your neck—the one you think is a birthmark—it's a seal. A lock on your true nature." He raised his hand, and I flinched, but he only pointed at my throat. "They're afraid of what you'll become."

I opened my mouth to scream.

Not for help. For Kael. For my Alpha. For the man I loved.

But Darius was faster. His hand closed around my wrist, not painfully, but firmly. His silver eyes burned into mine. "Don't," he said quietly. "Not yet. Just listen—"

"Get away from her."

The voice was a whip crack of command, pure Alpha dominance that made the trees shake and the snow tremble. Darius's grip vanished instantly, and he stumbled back, raising his hands in a gesture of surrender.

Kael stood at the edge of the clearing.

He was still in his human form, but barely. His eyes bled gold, and his canines had lengthened, sharp and deadly in the moonlight. He was naked too—he must have shifted mid-run—but he didn't seem to feel the cold. His entire body was coiled tension, muscle and fury and barely restrained violence.

My mate. My Alpha. My heart.

"Kael," I breathed, relief flooding through me so fast my knees nearly buckled. "He's hurt. I was just—"

"Step away from him, Elara." Kael's voice was ice. He didn't look at me. His eyes never left Darius's face. "Now."

I moved without thinking, putting distance between myself and the stranger. But Darius only smiled wider, spreading his arms as if welcoming an old friend.

"Kael," he said, savoring the name. "It's been a long time. You've grown into quite the Alpha. Though I see your taste in Lunas remains... unconventional."

Kael shifted.

One moment he was standing ten feet away. The next, he was in front of me, his body a wall of heat and muscle between me and Darius. His hand found mine, squeezed once, hard. A warning. Stay behind me.

"Darius died fifteen years ago," Kael growled. "You're not him. You're a ghost. A pretender."

"Am I?" Darius tilted his head, and the motion was so fluid, so predatory, that my skin crawled. "Then why does your heart beat faster, little Alpha? Why do your hands shake? Because you know who I am. And you know why I'm here."

"You're here to die. Again."

"Perhaps." Darius's smile didn't waver. "But not tonight. Tonight, I'm just here to deliver a message." His silver gaze slid past Kael and landed on me, hot and knowing. "Your Luna saved my life. That creates a bond. A debt." He paused, and when he spoke again, his voice dropped to a whisper that somehow carried through the clearing. "I'll collect it soon."

Then he was gone.

Not running. Not shifting. Just—gone, like smoke in the wind. One second he was there, and the next, only the falling snow remained.

Kael turned to me so fast I stumbled. His hands cupped my face, tilting it up, searching my eyes. "Did he touch you? Did he say anything? What did he tell you?"

"He—nothing. He just woke up. I healed him, and then—"

"You healed him?" Kael's voice cracked, and for the first time since I'd known him, I saw fear in his golden eyes. Real, raw, terrible fear. "Elara. Do you have any idea what you've done?"

"I saved a life. That's what Lunas do."

"He's not just a life." Kael pulled me against his chest, his arms wrapping around me so tightly I could barely breathe. His heart hammered against my ear, wild and panicked. "He's a monster. A traitor. The reason the three packs almost destroyed each other." He pressed his lips to my hair, and I felt him shake. "And now he knows you exist. Now he knows your scent. Your face. Your power."

"I don't have any power. I'm just a half-blood."

Kael pulled back, just enough to look into my eyes. His expression was raw, tortured, full of secrets he'd never told me.

"That's what I wanted you to believe," he said quietly. "That's what I needed everyone to believe." His thumb traced my jaw, gentle despite the tremor in his hand. "But Darius was right about one thing, Elara. I haven't told you everything."

"What do you mean?"

He opened his mouth to answer.

And then the howl cut through the night.

Not one wolf. Dozens. Surrounding us. Closing in.

Kael's face went pale. "They found him," he whispered. "The American Pack. They followed his trail."

"Kael—"

He kissed me then, hard and desperate, a kiss that tasted like fear and love and goodbye. When he pulled back, his eyes were no longer afraid. They were cold. Alpha.

"Go back to the den," he ordered. "Lock the door. Don't come out until I find you."

"What about you?"

"I'm going to do what I should have done fifteen years ago." He shifted, his body flowing into the massive black wolf I knew so well. His voice echoed in my mind, a mate's bond stretched to its limit. "I'm going to end this. Before he takes you away from me."

He disappeared into the trees.

And I was alone in the snow, naked and shaking, with the howls of enemy wolves growing closer and the taste of my Alpha's fear still on my lips.

The moon slipped behind a cloud.

The snow turned red.

And somewhere in the darkness, Darius laughed.

Kael didn't speak to me on the way back to the den.

He didn't need to. His silence was louder than any words, heavier than the snow that had started falling again, thicker than the blood still drying on my hands. Darius's blood. The blood I'd spilled trying to heal a monster.

The European Pack's den was carved into the heart of a mountain, hidden behind a waterfall that froze solid in winter. It had been my home for three years—ever since Kael had brought me here, a stray half-blood with no pack and no future, and made me his Luna. The tunnels were warm, lit by torches that smelled of pine and old magic. The walls were lined with tapestries depicting our history: great hunts, ancient battles, Alphas who had ruled for centuries.

None of those tapestries showed a half-blood.

Kael pulled me through the main hall without looking at the guards who bowed their heads. Without acknowledging the whispers that followed us. The Luna is bl
