Crimson Thirties

Chapter 4

The aisle stretched like an endless gauntlet.

Isolde walked it slowly, deliberately, every step measured to the thunder of her pulse. Cassian’s arm beneath her fingers was steel wrapped in velvet steady, unyielding, the only anchor in a sea of staring eyes.

The cathedral was a masterpiece of shadows and light: vaulted ceilings soaring into darkness, stained glass bleeding crimson and gold across marble floors, chandeliers dripping crystals that caught the flicker of a thousand candles. Lycan banners of silver and black hung beside vampire crests of deep scarlet uneasy allies united for one day.

And every soul in the room was holding its breath.

Whispers rippled outward as she passed. Nobles who had bowed to her for three years now stared openly at the ruin of her gown lace torn at the shoulders, silk stained with blood and other things, the fresh mating mark livid against her pale throat. The scent of s*x and Lycan claim clung to her like smoke.

She felt Vivienne’s gaze like a blade between her shoulder blades.

The real princess sat in the front pew on the bride’s side, posture perfect, hands folded in her lap. The black diamond choker hid the healing bite on her own throat, but her eyes those identical storm-gray eyes burned with barely leashed fury. When Isolde met them, Vivienne’s lips curved in a smile sharp enough to draw blood.

The archbishop waited at the altar, ancient and frail, clad in robes of midnight blue embroidered with both moon and blood runes. His hands trembled as he opened the ceremonial tome. Even he knew something was wrong.

Cassian handed her up the three shallow steps. His fingers brushed hers one brief squeeze of reassurance before he took his place facing her.

The organ fell silent.

In the hush, Isolde heard her own heartbeat. And another. Vivienne’s. Perfectly synchronized, as if their shared blood refused to acknowledge the war between them.

The archbishop began.

“Beloved children of moon and night, we gather beneath ancient pact to bind king and consort in blood and vow…”

Standard words. Beautiful words. Isolde barely heard them.

Her attention was fixed on the shadows at the edges of the cathedral. Vampire guards in crimson livery stood too still. Lycan enforcers in silver-trimmed black flexed claws beneath folded arms. Both sides waiting for a signal.

Cassian’s voice cut through the ritual like a blade.

“I, Cassian Voss, King of the Lycan Clans, take thee…”

He spoke the vows without hesitation, eyes locked on hers. Golden. Possessive. Promising everything and nothing.

When it was her turn, Isolde’s voice did not waver.

“I, Vivienne Draven…” The lie tasted like ash, but she forced it out smooth and clear. “Take thee, Cassian Voss, as my king, my mate, my eternal bond.”

A murmur swept the congregation. Some had expected her to falter. To reveal the impostor beneath the skin.

She did not.

The archbishop lifted the chalice ancient silver etched with runes that glowed faintly. Inside swirled a mixture of Lycan and vampire blood, drawn fresh that morning. The final binding.

“Drink,” he intoned, “and be forever joined.”

Cassian took it first. Drank deeply. A single drop of crimson lingered on his lower lip as he passed it to her.

Isolde raised the cup.

Time slowed.

She saw Vivienne rise slowly from her seat. Saw the duke her father place a restraining hand on the princess’s arm. Saw Vivienne shake it off with chilling calm.

The chalice touched her lips.

Cool metal. Warm blood.

She drank.

Power slammed into her like lightning.

The mingled blood of two ancient lines ignited in her veins Lycan fire and vampire ice twisting together, seeking harmony or destruction. Her knees buckled for a heartbeat, but Cassian’s hand at her elbow held her upright.

The bond flared brighter. She felt him his rage, his fear, his desperate hunger to protect what was his.

And something else.

A third presence.

Cold. Ancient. Watching.

Vivienne’s blood in the chalice had been stronger than expected. Pure royal line, undiluted. It whispered to the vampire essence in Isolde’s borrowed body, calling it home.

For one terrifying moment, Isolde felt herself slipping control fraying like thread as the real Vivienne’s essence tried to reclaim its vessel.

No.

She clamped down hard, forcing the foreign power into submission. The cathedral spun, then righted itself.

The archbishop was speaking again.

“…and now, by the laws of moon and blood, I declare you king and queen, bound until the stars fall.”

Applause thundered polite from the vampires, enthusiastic from the Lycans.

But it fractured almost immediately.

Vivienne stepped into the aisle.

Every guard tensed. Claws extended. Fangs flashed.

She walked forward with the grace of a predator, gown whispering over marble, until she stood at the foot of the altar steps. Directly below Isolde.

“Forgive the interruption,” Vivienne said, voice carrying effortlessly to the rafters. “But there is a matter of… authenticity… that must be addressed before the coronation feast.”

The duke rose behind her, face ashen. “Daughter”

Vivienne ignored him. Her eyes never left Isolde’s.

“I claim the right of Blood Challenge,” she announced. “As the true Princess Vivienne Draven, I accuse this woman of theft of my body, my name, my birthright. Let the ancient laws decide who wears this face rightfully.”

Gasps echoed like gunshots.

Blood Challenge. An archaic rite, invoked only thrice in recorded history. Two claimants to the same royal bloodline fought to the death in a circle of consecrated silver. The survivor absorbed the loser’s essence completely body, memories, power.

No impostor could survive it.

Isolde felt Cassian’s fury through the bond—a tidal wave barely contained.

“The challenge is invalid,” he snarled, stepping forward. “The vows are spoken. The bond is sealed. She is my queen.”

Vivienne smiled. “Is she? Then let the circle prove it.”

She drew a small vial from her sleeve crystal, stoppered with wax and smashed it at the base of the altar.

Black liquid spread across the marble, eating through stone like acid. Runes flared to life beneath the surface, ancient and hungry. A perfect circle twenty feet across formed around the altar, trapping Isolde, Cassian, Vivienne, and the archbishop inside.

The congregation recoiled as silver flames erupted along the boundary harmless to spectators, lethal to anyone trying to cross without permission.

The challenge had been accepted by the old magic itself.

Cassian rounded on Vivienne, claws fully extended, beast rising in his eyes. “You’ll die for this.”

“Perhaps,” Vivienne said. “But so will your false queen.”

The archbishop, trembling, backed away until the flames stopped him. “The laws are clear,” he whispered. “Only one may leave the circle alive. The magic will not release until blood decides.”

Isolde’s mind raced.

She had minutes seconds to find a way out.

The circle would amplify vampire traits in this body. Vivienne, as the true owner, would have every advantage: speed, strength, regeneration. Isolde’s human soul, even housed in vampire flesh, would be slower. Weaker.

And if she lost, Cassian would be trapped with a victorious Vivienne bound by vow and bond to the woman he’d never wanted.

She couldn’t let that happen.

Cassian moved to place himself between them, but Isolde caught his arm.

“No,” she said quietly. “This is mine to finish.”

His jaw clenched. “I won’t watch you die again.”

“You won’t have to.”

She stepped forward, descending the altar steps until she stood face-to-face with Vivienne inside the glowing circle.

Up close, the resemblance was horrifying. Same height. Same curves. Same fangs glinting in the candlelight.

Only the eyes differed now Isolde’s burning with human desperation, Vivienne’s cold with centuries of entitlement.

“Rules?” Isolde asked.

Vivienne’s smile widened. “None. Until one heart stops.”

They circled.

The cathedral held its collective breath.

Vivienne struck first inhumanly fast, claws raking for Isolde’s throat.

Isolde ducked, barely, feeling the wind of the strike part her hair. She countered with a kick to the knee street fighting, dirty and effective. Bone cracked. Vivienne hissed but didn’t slow; the joint knit as she spun, elbow slamming into Isolde’s temple.

Stars exploded across her vision.

She staggered, tasting blood. Vivienne pressed the advantage, fangs snapping for her jugular.

Isolde twisted at the last second, taking the bite on her shoulder instead the unmarked one. Pain seared white-hot as venom flooded muscle.

But she’d planned for this.

She let her body go limp, feigning collapse.

Vivienne followed her down, eager for the kill, mouth opening for the fatal strike.

Isolde surged upward, driving a concealed silver hairpin stolen from her ruined updo straight into Vivienne’s eye.

The princess screamed, reeling back.

Silver burned vampire flesh like acid. The wound wouldn’t heal quickly.

Isolde rolled away, scrambling to her feet. Blood poured from her shoulder, but the mating bond thrummed with Cassian’s strength, lending her speed.

Vivienne tore the pin free with a wet sound, eye already regenerating but slowly. Rage twisted her beautiful face into something monstrous.

“You dare”

She blurred forward.

This time Isolde was ready.

She met her head-on claws clashing, fangs snapping, bodies slamming together with bone-jarring force. They grappled like mirror images, each anticipating the other’s moves with terrifying accuracy.

Vivienne gained the upper hand, pinning Isolde against the altar. One hand clamped around her throat, squeezing.

“Feel that?” Vivienne whispered. “Your stolen heart slowing. My body rejecting you.”

Black spots danced in Isolde’s vision.

But she smiled.

“Look closer,” she rasped.

Vivienne frowned and felt it.

The bond.

Not just Cassian’s mating mark.

Something deeper.

During the chalice rite, when the mingled blood had ignited, Isolde had done more than fight for control.

She’d reached through the bond to Cassian and pulled.

Lycan essence now coursed through her veins alongside vampire blood. Hybrid power. Unstable. Dangerous.

But enough.

Her claws lengthened Lycan black instead of vampire white.

She drove them upward under Vivienne’s ribs, piercing heart in a single brutal thrust.

Vivienne’s eyes widened in shock.

Blood hot, royal, ancient poured over Isolde’s hand.

The circle’s flames roared higher, sensing death.

Vivienne slumped, body sagging against her. Her mouth worked soundlessly.

Isolde leaned close.

“This face,” she whispered, “this life… I earned them both. In ways you’ll never understand.”

She twisted her claws.

Vivienne’s heart stopped.

The silver flames died instantly.

The circle broke.

Isolde stood alone in the center, covered in blood that wasn’t hers, holding the lifeless body of the true princess.

Silence reigned for one endless second.

Then Cassian was there catching her as her legs gave out, cradling her against his chest.

The congregation erupted—some in horror, some in triumph. Vampire lords shouted accusations. Lycan packs howled approval.

But the magic had spoken.

The archbishop, voice shaking, raised his arms.

“By blood and by challenge… the queen stands victorious.”

Isolde lifted her head.

Her eyes met the duke’s across the chaos. He stared at his daughter’s corpse, face blank with grief.

Then, slowly, he bowed.

One by one, the vampire delegation followed.

Submission.

Acceptance.

Cassian’s arms tightened around her.

Through the bond, she felt his awe. His pride. His fear for how close he’d come to losing her again.

Isolde buried her face in his neck, breathing him in.

Thirty nights remained.

But now the prophecy had a new interpreter.

And she intended to rewrite every line in blood.
