BackMarked by the Wolf King

Chapter 5 - Stolen Key

AMBER

The silence after Kaelen leaves the library is heavier than before. Not just with tension—though that hums beneath my skin like a struck wire—but with something worse: uncertainty.

I came here with a mission. Clear. Cold. Uncomplicated.

Destroy the Heartstone. Break the curse. Free my mother’s soul.

But now? Now I know the truth—that the curse was never just about us. That the first Wolf King and Lord Vexis forged it together, a weapon disguised as protection, a prison built on betrayal. And that Kaelen… isn’t the monster I thought he was.

He’s trapped too.

And worse—he *knows* it. He’s been searching, just like me. He wants out. Not just for power. For survival.

But that doesn’t change what I saw. The way Selene touched his scar. The way she smiled when she called me *sister*. The way he didn’t deny her, not at first. The way he still carries that mark, like a wound he refuses to heal.

I press my palm to the shelf beside me, grounding myself. The bond pulses in my veins, slow and steady, a constant reminder that I’m not alone in this. That he’s always near. Always watching. Always *feeling*.

I can’t trust him.

Not yet.

But I can use him.

Because if the curse can only be broken with a lie as sacrifice, then I need proof. I need Vexis’s blood. Or his name. Or the ritual itself, complete and unaltered. And the one place I haven’t searched—the one place even Kaelen might not have access to—is the Heartstone Chamber.

Locked. Warded. Guarded.

And I need the key.

I wait until nightfall.

Until the torches in the palace corridors burn low. Until the Enforcers shift their patrols. Until the bond between us dulls to a faint thrum, distant, like a storm retreating over the mountains.

Kaelen is in his chambers. I can feel him—his presence, his heat, his restlessness—like a weight against my spine. But he’s not coming for me. Not yet. He’s giving me space. Testing me. Waiting to see if I’ll break.

I won’t.

I move like shadow.

Black tunic. Soft boots. Hair bound tight. My magic coiled low, barely a whisper, just enough to mask my scent, to mute my footsteps. I slip from the guest chamber, down the east wing, toward the private royal quarters. Kaelen’s rooms are at the end of the hall—guarded by two Enforcers, posted like statues on either side of the arched doorway.

I don’t go in.

I go *above*.

The Blackfang Palace was built into the mountain, its stone walls carved from the living rock. Ancient, but not impenetrable. And like any fortress, it has weaknesses—vents, service tunnels, forgotten passages. I found one during my first night here, hidden behind a tapestry in the library: a narrow shaft, barely wide enough to crawl through, that runs along the ceiling beams and drops down behind the council chamber. From there, it branches—north to the armory, south to the royal wing.

I take the south branch.

The air is stale, thick with dust. I crawl on hands and knees, my breath shallow, my pulse slow. The bond tugs at me, faint but insistent, like a leash I’m trying to ignore. I focus on the mission. On the key. On the lock that only opens to the Alpha’s blood and the High Council’s decree.

But I know another way.

There’s a rumor—whispered in the lower coven texts—that the original key to the Heartstone Chamber wasn’t metal. It was bone. Carved from the first Wolf King’s rib, enchanted to respond only to his bloodline. And if Kaelen is truly the last of the Stormborn, then the key should be somewhere in his private vault.

And if it’s there… I can take it.

The shaft opens into a small alcove behind a bookshelf in the study adjacent to his bedroom. I ease the panel aside, slip through, and press myself against the wall. The room is dark, lit only by the dying embers in the hearth. Books line the shelves—military strategy, pack law, ancient treaties. A desk sits in the center, carved from black oak, its surface cluttered with scrolls, maps, a dagger still in its sheath.

And on the far wall—a door.

Iron. Rune-etched. Unmarked.

The vault.

I move toward it, silent, careful. My fingers brush the cold metal. No handle. No keyhole. Just a small indentation in the center, shaped like a wolf’s paw.

Blood lock.

I pull a thin blade from my boot—witchsteel, sharp enough to slice through skin without breaking the surface. I press it to my thumb, draw a single drop of blood, and smear it into the indentation.

Nothing.

Of course not.

The vault only opens to Stormborn blood.

I curse under my breath. I need another way. A distraction. A way to get him out of his room, even for a moment.

And then—

A sound.

Boots on stone. Heavy. Deliberate.

Coming down the hall.

I freeze.

The Enforcers shift. A low murmur. Then—

“Alpha.”

“What is it?” Kaelen’s voice. Rough. Sleep-roughened.

“Rider from the northern border. Says the Fae are massing near the Veil.”

A pause. Then, “Bring him to the war room. I’ll be there in five.”

Footsteps retreat. The Enforcers move with him.

He’s leaving.

Now.

I don’t hesitate.

I dart to the bedroom door, ease it open just enough to slip through. The room is vast—stone walls, furs on the floor, a massive bed carved from black wood. But I don’t look at it. I go straight to the wardrobe, the one I noticed earlier, its back panel slightly ajar.

Another passage.

I’ve seen this before—old shifter architecture. Royals built escape routes into their chambers. This one likely leads to the battlements or the armory. But more importantly, it’s *unlocked*.

I slip inside, close the panel behind me.

The passage is narrow, sloping downward. I follow it, heart pounding, until it opens into a small chamber—round, stone, lit by a single flickering torch. And in the center, on a pedestal of black iron, rests the key.

Not metal.

Bone.

Carved into the shape of a wolf’s fang, its surface etched with ancient runes. It pulses faintly, like a heartbeat. And around it, a ring of salt, crushed obsidian, and dried blood—wards. Powerful ones. Meant to keep thieves out. Or witches in.

I don’t touch the circle.

Instead, I pull a small pouch from my sleeve—moon-dust, mixed with ash from a burned contract. I sprinkle it over the wards. The salt hisses. The obsidian cracks. The blood smokes.

The circle breaks.

I step forward, reach for the key—

And the torch snuffs out.

Darkness.

Then—

Heat.

Behind me.

Before I can turn, a hand closes around my wrist—iron grip, unbreakable. Another wraps around my waist, yanking me back against a hard chest. I smell pine. Smoke. Iron.

Kaelen.

“I knew you’d come,” he growls in my ear. “I *felt* you.”

My pulse roars. The bond surges, not with desire this time, but with danger. I twist, elbow flying back—but he catches it, pins both my arms above my head with one hand. His body is a wall against mine, unyielding, overwhelming.

“Let me go,” I hiss.

“No.”

“You have no right to hold me.”

“You broke into my vault. Tried to steal the Heartstone key. I have every right.”

“I’m not stealing it,” I lie. “I’m *borrowing* it.”

He laughs—low, dark. “You’re a terrible liar, Amber. The bond tells me everything. Your heartbeat. Your breath. The way your magic spikes when you deceive me.”

“Then you already know why I’m here.”

“To break the curse,” he says. “But not yet. Not like this.”

“And what would you have me do?” I snap. “Wait? Hope you decide to help me? While Selene whispers in your ear and the Heartstone drains us both?”

He doesn’t answer.

Instead, he turns me, slowly, until I’m facing him. The darkness makes his eyes glow—gold, predatory, *hungry*. One hand still holds my wrists. The other slides to my throat, not squeezing, just resting there, thumb brushing my pulse.

“You think I don’t want out?” he says, voice rough. “You think I enjoy this? The pain? The weakness? The way my pack looks at me like I’m already dead?”

“Then help me,” I whisper. “Give me the key. Let me finish what I came here to do.”

“And if I do,” he says, “you’ll destroy the Heartstone. Kill me. Kill my pack. Burn everything to the ground.”

“Not if I do it right,” I say. “The ritual requires a lie as sacrifice. If I speak the truth instead—if I offer *us* as the new pact—maybe we can break the curse *without* destroying the Heartstone. Maybe we can free my mother’s soul *and* save your pack.”

He stares at me. For the first time, I see something flicker in his eyes—hope. Fear. Wonder.

“You’d do that?” he asks. “Risk everything… for me?”

“Not for you,” I say. “For *us*.”

He doesn’t move. Doesn’t speak. Just watches me, his thumb still stroking my pulse, his breath hot against my skin.

Then—

A sound.

From the passage.

Footsteps.

Too light for Enforcers.

Too silent for humans.

Vampire.

Kaelen hears it too. His grip tightens. His body shifts, shielding me without thought. Protecting me.

“Selene,” he mutters.

And then she’s there—gliding into the chamber, pale as moonlight, her silver hair falling over one shoulder, her crimson lips curved in a smile.

“Kaelen,” she purrs. “I felt your distress. Came to offer… comfort.”

Her eyes flick to me. “Oh. I see you’re *busy*.”

“Get out,” Kaelen growls.

“Or what?” She steps closer. “You’ll mark her? Claim her? While you still carry *my* bite on your skin?”

“That mark means nothing,” he says.

“It means *everything*,” she whispers, reaching out, fingers brushing his chest. “It means you were mine before she was born. That you’ll *always* be mine.”

My jaw clenches.

The bond flares—hot, jagged, *possessive*.

And before I can stop myself, I twist in Kaelen’s grip, kick out—and my boot connects with Selene’s stomach.

She stumbles back, snarling, fangs bared.

“You little *witch*—”

Kaelen moves.

In a blur, he’s between us, fangs bared, eyes blazing gold. “Touch her,” he snarls, “and I’ll rip your heart out.”

Selene laughs, sharp and cruel. “Oh, Kaelen. You’ve always had a weakness for defiant women. But this one?” She gestures at me. “She’ll destroy you. And when she does, I’ll be there to pick up the pieces.”

And then she’s gone—vanished into the shadows, leaving only the echo of her laughter.

Silence.

Kaelen turns to me. Still holding my wrists. Still close. Still *dangerous*.

“You didn’t have to do that,” he says.

“She was touching you,” I say, voice low. “Like she owned you.”

“She doesn’t.”

“But you let her.”

He exhales. “I didn’t. Not tonight. Not ever again.”

And then—

He releases me.

Steps back.

Reaches into the circle. Picks up the key.

And hands it to me.

“Take it,” he says. “Use it. Break the curse. But do it *with* me. Not against me.”

I stare at him. “Why?”

“Because I believe you,” he says. “Not because of fate. Not because of the bond. But because you *fought* for me. Even when you hate me. Even when you think I’m a monster.”

My breath catches.

He steps closer. One hand lifts. Hovers near my face. Doesn’t touch.

“So let me stand with you,” he murmurs. “Let us break the curse. Together.”

I look down at the key in my hand. Bone. Cold. Alive.

Then up at him.

At the man who executes traitors in moonlight. Who carries scars like secrets. Who just handed me the power to destroy him.

And for the first time, I don’t see an enemy.

I see a partner.

“Together,” I say.

He nods.

And the bond—silent for a heartbeat—sings.
