The first thing I feel is the cold.
Not the kind that bites at your skin, the way winter does in the Fae Wilds. No. This is deeper. It seeps into the marrow, gnaws at the magic in your blood. Iron. Suppressing runes. Years of it. They’ve had me chained in the forge—the heart of the Iron Court—where the fire never dies, but the magic is leashed. I’ve been here so long I can’t remember the taste of clean air, the scent of pine, the sound of a living forest. Just smoke. Coal. The hum of machines. The whisper of spells gone sour.
And then—
They come.
Not quietly. Not with stealth. But with *force*.
The gate screams open. Ice cracks the sigils. Boots echo on black stone. And I know, before I even see her, that she’s here.
Birch.
My child. My creation. The girl I grafted with thorn-blood to save her life, raised in the shadows, taught to fight, to lie, to survive. The girl I let believe I was dead so she wouldn’t break under the weight of the truth.
She steps into the chamber like a storm given form—dark hair pulled back, leather tight across her shoulders, her storm-gray eyes burning with something I haven’t seen in ten years: *recognition*.
Not of me.
Of herself.
“You’re late,” I say, voice rough, testing.
She doesn’t flinch. Just stares at me, her breath catching, her fingers twitching at her sides. “You’re alive,” she whispers.
“Obviously.” I smirk. “Did you really think a few chains and a half-blood tyrant could keep me down?”
She steps closer. Cassian follows, silent, watchful. Kael lingers at the door, his amber eyes scanning the shadows. The bond hums between them—warm, restless, *alive*. I feel it. Not just in the air, but in my bones. It’s stronger now. Deeper. Not just magic. Not just fate. *Love*.
And it terrifies me.
Because love is the most dangerous weapon of all.
“You knew?” Birch demands, her voice sharp. “You knew Cassian had you here?”
“Of course I did.” I glance at him. “He’s not as clever as he thinks.”
Cassian doesn’t react. Just watches me, his storm-gray eyes unreadable. “You’re the one who told me to keep you hidden. To protect you.”
“And you did.” I turn back to Birch. “But not for the reasons you think.”
“Then why?” she snaps. “Why let me believe you were dead? Why let me come here to kill him, to burn his legacy to ash, when you *knew* the truth?”
I don’t answer right away. I study her—her face, her stance, the way her thorns twitch beneath her skin. She’s stronger now. Harder. But not broken. Not yet.
“Because you weren’t ready,” I say.
“Ready for what?”
“For the truth.” I lift my chained hands. “The coven wasn’t destroyed by Cassian. It was *sacrificed* by your mother. To save you. To awaken the Thorn Pact. To bind you to him.”
Her breath stills.
“And the Heartroot?” she whispers.
“It wasn’t stolen.” My voice drops. “It *gave* itself. To save him. To save *us*.”
“And now?”
“Now it chooses.” I meet her eyes. “And I don’t care what it decides. Because I’ve already chosen *you*.”
The bond flares—warm, steady, *right*.
And for the first time since I walked into this court—
I believe her.
Not because of the magic.
Not because of the fire.
But because, in her eyes, I see it—
Not a mentor.
Not a savior.
But a woman who’s been as lost as I am.
And maybe—
Just maybe—
We’re not meant to burn each other.
Maybe we’re meant to burn the world—
And rebuild it from the ashes.
Together.
“Then why did you let me believe he was the enemy?” she asks, voice breaking.
“Because you needed to be angry.” I reach out—slow, deliberate—and touch her cheek. “You needed to fight. To burn. To *live*. And if I’d told you the truth, if I’d said, ‘Your mother sacrificed the coven to save you, and the man you’re supposed to kill is your fated king,’ you would have broken. You would have collapsed under the weight of it.”
“And now?”
“Now you’re strong enough.” I press my forehead to hers. “Now you’re ready.”
The bond *screams*—not in pain, not in warning.
In *recognition*.
And deep beneath the forge, in the vault where the Heartroot rests, its pulse stirs—*stronger now*—and for the first time in years, it burns.
Not in fear.
Not in warning.
In preparation.
But the moment doesn’t last.
Because the air shifts.
Not from wind.
Not from fire.
From *magic*.
Old. Twisted. *Familiar*.
“We’re not alone,” Kael says, hand on his blade.
Cassian turns, his storm-gray eyes scanning the shadows. “They’ve been watching.”
“Who?” Birch asks, stepping in front of me.
“Nyx,” Cassian says. “Or Silas. Or both.”
And then—
The runes on my cuffs *glow*—a sickly green, pulsing with dark energy. I gasp, my body arching as pain rips through me. “Run,” I hiss. “Now. It’s a trap. The whole place—”
But I don’t finish.
Because the floor *explodes*.
Black vines erupt from the stone—thick, thorned, *alive*—writhing like serpents, lashing out, wrapping around their legs, their arms, their throats. Birch screams, slashing with her dagger, but the vines are fast, stronger than any magic I’ve ever faced. They *pull*, dragging her down, pinning her to the ground. Cassian roars, ice spiraling from his palms, freezing the vines, but more come. Kael fights like a wolf, tearing through them with claws and fang, but he’s overwhelmed.
And then—
Laughter.
Soft. Melodic. *Poisonous*.
Queen Nyx steps from the shadows—tall, elegant, draped in a gown of living ivy and moonlight. Her hair is black as midnight, her eyes golden, her smile sharp enough to cut. She doesn’t look at the bodies. Doesn’t flinch. Just watches us, amused, like we’re children playing at war.
“How touching,” she says, voice like silk over steel. “The cursed bond, finally reuniting the lost mentor. Did you enjoy it, Birch? Feeling her love? Tasting her lies? Or are you still pretending this is about *truth*?”
“You’re the liar,” Birch snarls, struggling against the vines. “You burned my coven. You stole the Heartroot. You bound us to destroy each other.”
“I didn’t bind you,” she says, tilting her head. “The Heartroot did. It chose you. Both of you. And now?” She smiles. “Now it’s watching to see if you’re worthy.”
“Worthy of what?”
“Rule.” She steps closer. “The old world is dying. The Veil is thin. The Council is weak. And the Heartroot?” She laughs. “It doesn’t want a warden. It wants a *king and queen*. Born of fire and thorn. Bound by blood. Meant to burn the old order to ash.”
My stomach twists.
“You’re lying.”
“Am I?” She gestures to the vines. “Or am I just showing you the truth? That you’re already killing each other? That the bond is a *curse*? That no matter how many times you kiss, no matter how many times you *burn* for each other, you’ll never escape what you are?”
“We’re not pawns,” Cassian growls, ice cracking the vines around his wrists. “We’re not your weapons.”
“Aren’t you?” She smiles. “You’ve spent your lives proving you’re not weak. That you’re not like your parents. That you’re not *half-breeds*. And yet—” Her gaze flicks to Birch. “—you’re bound to her. And you—” She looks at Cassian. “—you’re dying. And the only thing keeping you alive is the very magic you claim to protect.”
“The Heartroot chose me,” he says.
“And now it’s choosing *her*.” She steps closer. “I didn’t engineer the bond, Cassian. I just *awakened* it. I lit the fuse. And now?” She smiles. “Now the explosion is coming. And when it does—”
“You’ll be ready to pick up the pieces,” Birch says.
“Exactly.” She turns, begins to walk away. “Enjoy your fire, little witch. Savor your king. Because soon—”
“Wait.” Cassian’s voice cuts through the chamber like ice. “You left something behind.”
She pauses. “Oh?”
He doesn’t answer. Just *moves*—fast, silent, a shadow given form. The vines try to stop him, but he’s faster, ice spiraling from his palms, freezing them, shattering them. He reaches me, presses his marked hand to my cuffs—
And the runes *shatter*.
I gasp, collapsing into Birch’s arms. “The forge,” I whisper. “It’s not just a prison. It’s a *key*. The Heartroot—”
But I don’t finish.
Because Nyx *laughs*.
And the walls *explode*.
Not with fire.
With *sound*.
A sonic blast rips through the chamber, throwing us back, shattering the iron walls, collapsing the ceiling. Dust and debris rain down. Birch shields me, rolling, crawling, dragging me toward the edge of the chamber. Cassian grabs Kael, pulling him behind a fallen beam. The vines retreat, writhing back into the stone.
And Nyx?
She’s gone—vanishing into the shadows like smoke.
“We can’t stay,” Birch says, voice tight. “She’ll bring more. Traps. Assassins. The whole Court’s rigged.”
“Then we move fast,” Cassian says, rising. “We get her out. We find the vault. We take the Heartroot.”
“And if it’s a trap?” Kael asks.
“It is,” I say, coughing. “But it’s the only way. The forge holds the last piece of the Thorn Pact. The ritual that bound you. If you don’t claim it, the bond will break. And you’ll both die.”
My breath stills.
“Then we go,” Birch says.
Cassian nods. “Together.”
We move.
Through the collapsing corridors, past falling beams and burning machinery. The air is thick with smoke, the floor slick with oil and blood. Kael leads, silent, watchful, his amber eyes scanning for traps. Cassian stays close, his hand never far from Birch’s, the bond flaring—heat rolling through us, sudden and deep. I lean on Birch, weak, trembling, but alive. Her breath is ragged, her pulse faint, but her grip is strong.
And then—
A door.
Black iron. Sealed with a sigil that pulses with dark energy. The Thorn Pact. I feel it—the pull, the *recognition*—like a key turning in a lock.
“This is it,” I whisper. “The heart of the forge. The vault.”
Cassian raises his hand—ice spiraling—but before he can strike, the door *opens*.
Not from magic.
From *inside*.
And standing there—
A man.
Human. Tall. Sharp suit. Cold eyes.
Director Silas.
“Welcome,” he says, smiling. “I’ve been waiting for you.”
The bond *screams*—not in pain.
In *warning*.
And deep beneath the forge, in the vault where the Heartroot rests, its pulse stirs—*stronger now*—and for the first time in years, it burns.
Not in fear.
Not in warning.
In preparation.
—
Silas doesn’t move. Just stands there, hands in his pockets, that cold smile on his face. Behind him, the vault glows—walls of black iron etched with ancient sigils, the air thick with power, old and deep. And at the center—
The Heartroot.
Not a book. Not a weapon. A living grimoire of twisted bark and pulsing veins, its surface etched with shifting sigils that writhe like serpents. It hums—low, steady, *alive*—its pulse matching the rhythm of the bond.
“You’re not supposed to be here,” Cassian says, stepping forward.
“But I am,” Silas replies. “And so are you. Which means the plan is working.”
“What plan?” Birch demands, her voice sharp.
“The same one Nyx has been playing,” I say, coughing. “She wanted you to come. She wanted you to find me. She wanted you to come here—to this vault—so she could watch you destroy each other.”
“And you’re helping her?” Cassian asks.
“No.” Silas smiles. “I’m helping *myself*.”
He steps aside—just enough to reveal the machine behind him. A cage of black iron and glowing wires, humming with stolen magic. Inside—
A vial.
Dark liquid sloshing inside. Blood. And in the torchlight, I see it—
The sigil of the ISO.
“You’re harvesting it,” I whisper.
“Yes.” He turns to me. “The Heartroot’s blood. The magic that keeps Cassian alive. I’ve been siphoning it for months. Creating a synthetic strain. Stronger. Cleaner. No need for half-blood kings. No need for cursed bonds.”
“You’re a fool,” Cassian says, voice deadly quiet. “The Heartroot isn’t just magic. It’s *alive*. It’s *choosing*. And it will never serve you.”
“It already has.” Silas reaches into his coat, pulls out a syringe filled with dark liquid. “One injection. That’s all it takes. I’ve already tested it. On hybrids. On witches. On werewolves.” He smiles. “They obey me now. Without question.”
Birch steps forward, her thorns blooming across her arms. “You don’t get to do this.”
“Oh, but I do.” He raises the syringe. “Because soon, I won’t just control the Blood Markets. I’ll control the Council. The Courts. The *world*.”
And then—
He lunges.
Not at Cassian.
Not at Birch.
At *me*.
I don’t have time to move. Don’t have the strength. But Birch does.
She throws herself in front of me—thorns erupting from the floor, forming a shield. The syringe slams into it, shattering, dark liquid splattering across the stone. Silas snarls, pulls a blade—
And Cassian freezes him.
Ice spirals from his palm, fast and precise, encasing Silas from the neck down. He struggles, but the ice holds. His eyes blaze with fury.
“You’re too late,” he spits. “The strain is already in circulation. The hybrids are mine. The Council will fall. And when the Heartroot dies—”
“It won’t,” Birch says, stepping forward. “Because I won’t let it.”
She turns to me. “Tell me what to do.”
I press a hand to my chest, over the old scar where I once grafted the thorn-blood into her heart. “The ritual,” I whisper. “The Thorn Pact. It wasn’t just a binding. It was a *transfer*. Your mother didn’t just save you. She gave you a piece of the Heartroot. A seed. And now—”
“—it’s time to claim it,” Cassian says.
“Together,” Birch says.
They step into the vault.
Hand in hand.
The bond *roars*—heat, magic, desire crashing through them like a storm. The thorns on their arms *erupt*, black vines blooming across their skin, wrapping around each other, binding them together.
And deep beneath the forge, in the vault where the Heartroot rests, its pulse stirs—*stronger now*—and for the first time in years, it burns.
Not in fear.
Not in warning.
In approval.
Queen Nyx, watching from a scrying pool in the Summer Court, smiles.
“Good,” she whispers. “Let them burn for each other.”
“And when they do?” asks a shadowed figure beside her.
“Then we take everything.”
She turns from the pool, her golden eyes glowing with malice.
“The real game has just begun.”
