BackScarlet Vow

Chapter 1 - Blood Bond Ignites

LAVENDER

The first thing I notice about Kaelen is the ring.

It glints under the cold chandeliers of the Blood Garden, a black stone set in silver, etched with the sigil I’ve spent my life memorizing: three interlocking chains, the mark of the Blood Vow. My mother’s sigil. The one that bound her soul to eternal servitude. The one that made her beg for death every night until she forgot how to scream.

He’s standing in the shadows, one hand gripping the throat of a fae courtesan, his mouth at her neck. Blood glistens on his lower lip. His eyes are closed, his body still, like a predator savoring the kill. He doesn’t look like a prince. He looks like a blade wrapped in silk.

I don’t flinch. I don’t look away.

I study.

My name is Lavender, and I am not who they think I am. I am not the envoy from the Northern Coven, here to witness the treaty between the Fae High Court and the Obsidian Vampire Court. I am not the witch with the sharp tongue and sharper magic. I am the daughter of Elara, the woman he destroyed. And I am here to burn his world down.

I adjust the high collar of my dress—black velvet, laced with iron thread to mask my scent—and step forward. The air is thick with glamour and blood, the kind of cloying sweetness that makes my stomach turn. Around me, vampires sip from crystal goblets, their fangs hidden behind polite smiles. Fae dance in shifting silks, their laughter edged with cruelty. This is the gilded cage of the Veil, where power is measured in oaths, and every alliance is sealed with pain.

The treaty signing is about to begin.

I take my place among the lesser envoys, near the back of the dais. My forged papers are flawless. My magic is suppressed. My dagger—laced with yew venom, enough to paralyze a vampire for hours—is strapped to my thigh, hidden beneath layers of fabric. I’ve planned every detail. Every escape route. Every contingency.

But I didn’t plan for him.

When Kaelen steps onto the dais, the room stills.

He doesn’t walk like a man. He moves like shadow given form—silent, inevitable. His coat is obsidian black, lined with silver thread that catches the light like veins. His hair is dark, cut short at the sides, longer on top, falling just above his brows. His face is all sharp angles: high cheekbones, a jawline like carved stone, lips that look made for cruelty.

And his eyes—

They’re the color of frozen blood. Red, but not bright. Deep. Ancient. The kind of red that’s seen centuries of war and liked it.

He scans the room, and when his gaze hits mine, I feel it like a physical touch—cold, invasive, hungry.

I don’t look away.

Let him see me. Let him remember my face. Because the next time he sees me, I’ll be the last thing he ever sees.

The Fae High King rises, his crown of thorns glowing faintly in the dim light. “Today, we seal the alliance between the Seelie Court and the Obsidian House. Let the Blood Vow bear witness to our unity.”

A collective breath. The Blood Vow. The most sacred—and most dangerous—of bindings. It’s not just a contract. It’s magic woven into flesh, enforced by the Oathweavers, the fae enforcers who stand at the edges of the room, their faces hidden behind silver masks.

Two servants step forward, carrying a stone tablet etched with runes. The treaty. Kaelen approaches first, his presence like a storm rolling in. I follow, my pulse steady, my breath controlled. I am a weapon. I am ready.

Then the High King says, “Place your hands upon the ward. Let the bond be tested.”

My blood turns to ice.

This wasn’t in the briefing. The treaty was supposed to be signed with ink, sealed with blood—but not a bond. Not a magical tether between envoy and prince.

I glance at the other envoys. No one else is moving forward.

“You,” the High King says, pointing at me. “Witch of the North. Step forward.”

There’s no choice. I step up beside Kaelen.

He doesn’t look at me. Doesn’t speak. But I feel him—the heat of his body, the slow, deliberate rhythm of his breath. He’s close enough that I can smell him: cold stone, old wine, and something darker—iron, maybe, or the faintest trace of blood.

Our hands hover over the tablet.

“Press your palms to the ward,” the High King commands. “Let the magic decide if this alliance is true.”

I glance at Kaelen. His jaw is tight. He doesn’t want this either.

But we both press down.

The moment our skin touches the stone, the world shatters.

A pulse of fire erupts from the tablet, slamming into us like a wave. My hand is wrenched toward his, fingers locking without my consent. Our palms press together, skin to skin, and then—

Blood.

A thin line splits open across both our hands, as if an invisible blade has sliced us. Our blood wells, dark and rich, and begins to mingle on the stone.

And then the bond ignites.

It’s not a feeling. It’s a violation. A flood of heat, of magic, of him pouring into me. I feel his thoughts like whispers in my skull—cold, calculating, dangerous. I feel his pulse, his breath, the way his body tenses when I try to pull away. I feel the way his gaze lingers on my throat, the way his fangs ache to sink in.

And beneath it all—

Desire.

Hot. Primal. Unwanted.

I gasp, staggering back, but our hands are fused. The bond won’t let us go. The runes on the tablet flare crimson, and a symbol burns itself into my wrist—a spiral with three chains, the sigil of the Blood Vow, now mine.

Kaelen’s eyes snap open. They’re blazing now, red fire in the dark. He looks at me—really looks—and for one breathless second, I see it: not hatred. Not power. Recognition.

As if he’s been waiting for me.

“What the hell is this?” I hiss, trying to yank my hand free. The magic burns, searing my skin.

“A forbidden bond,” the High King says, sounding almost pleased. “The ward has chosen. You are linked, Lavender of the North, and Kaelen, Prince of the Obsidian Court. Until the bond is proven or broken, you cannot be more than ten paces apart.”

My stomach drops.

This changes everything.

I came here to destroy him. To steal the Blood Vow contract from his vaults, break the spell on my mother’s soul, and vanish into the night. But now—now I’m bound to him. Magic won’t let me flee. It won’t let me kill him. Not without killing myself.

Kaelen finally speaks, his voice low, dangerous. “You’re not leaving my side. Not until this bond is proven.”

He grips my wrist, his fingers like iron. The bond flares again, a pulse of heat that races up my arm and settles low in my belly. I hate it. I hate him.

But my body—

My body betrays me.

My nipples tighten under my dress. My breath comes faster. Between my thighs, a slow, aching heat begins to bloom.

No. No. I won’t be used again. Not by a vampire. Not by him.

“You think this changes anything?” I snap, yanking my hand back. The bond resists, but I pull harder, teeth gritted. “I’m not your pawn. I’m not your mate.”

He steps closer, his body crowding mine. “You’re whatever I say you are. And right now, you’re mine.”

His breath brushes my ear. I shiver. I hate that I shiver.

“You don’t know me,” I whisper. “You have no idea what I’m capable of.”

“I know you’re lying,” he says softly. “I can feel it. The bond shows me your emotions. Your fear. Your rage. And beneath it all—”

His hand slides down my arm, fingers tracing the sigil on my wrist. Heat flares where he touches.

“—desire.”

I slap his hand away. “I’d rather die than want you.”

He smirks. Cold. Beautiful. Deadly. “Then you’ll die very, very slowly.”

Behind us, the court is murmuring. I catch fragments:

“A bond between witch and vampire? Unheard of.”

“She looks like she’s seen a ghost.”

“He’s going to break her. Just like the others.”

I ignore them. I focus on the mission. On the dagger at my thigh. On the fact that I now have to stay within ten paces of the man I came to destroy.

Kaelen turns to the High King. “The bond must be tested. Seven nights of proximity. Shared blood. Emotional honesty under truth magic.”

My stomach twists.

Seven nights. Trapped with him. Forced to share blood. To be honest.

“Agreed,” the High King says. “Fail the trial, and you’ll be executed for deception.”

Kaelen looks at me. “You hear that, witch? Fail, and you die.”

I lift my chin. “And if I win?”

“Then you’ll be free.”

But we both know the truth.

There is no winning. Only survival.

And the deeper I fall into this bond, the less I’m sure I want to survive it.

He releases my wrist, but the bond remains—a constant hum beneath my skin, a thread tying me to him. I can feel him like a second heartbeat, steady and dark.

“Come,” he says, turning. “You’ll stay in my wing.”

“I’d rather sleep in the dungeon.”

“Then you’ll sleep in the dungeon. But you’ll still be in my wing.”

I follow, every step a war. My mind races. How do I break the bond? How do I steal the Vow? How do I kill him without killing myself?

And then—

A whisper in my mind. Not mine.

You’re already mine.

I stop. Look back.

Kaelen hasn’t spoken. But his lips are curved in a faint smile.

The bond. He’s in my head.

I close my eyes. Breathe.

This isn’t over. Not even close.

I came here to destroy him.

But the bond has other plans.

And the most dangerous part?

As I walk behind him, watching the way his coat moves over his shoulders, the way his fingers flex at his side, the way his presence fills the room like a storm—

I think I might already be falling.
