Prologue

Before the First Door

My sister ties the red thread around my wrist and tells me it has never been there before.

Elara’s fingers are cold. They move with the precision of a court physician, circling the thread three times, knotting it over the pulse, cutting the loose end with the same knife I will use on the Minotaur. Dawn burns white through the execution chamber windows behind her.

“If you see this thread tomorrow,” she says, “you failed.”

I study her face. Elara has always been the softer Vale sister, built for astronomy tables and royal clocks rather than interrogation rooms. Tonight there are bruises beneath her eyes and a tremor in her left hand.

“There will be no tomorrow inside the labyrinth,” I say.

“That is what the king wants you to believe.”

The bronze doors at the far end of the chamber begin to turn.

Beyond them waits Asterion.

The palace calls it a prison. The priests call it a machine for choosing the merciful future. The soldiers who deliver criminals to its entrance call it a mouth. At sunrise, everyone inside loses the previous day. Everyone except the creature who guards its center.

Theron Aster.

The royal record names him man-eater, prince-killer, beast. It says his horns hold the discarded days of the kingdom and that cutting them will release the future Elara was stolen into.

I have read the order twenty times.

I still do not understand how my sister can stand before me if she is trapped in an erased day.

“You are a projection,” I say.

Elara flinches.

It is the first honest reaction I have seen from her tonight.

“Or you are,” she replies.

The doors complete another fraction of their turn. Red-painted stone appears through the widening seam. Warm air breathes out, carrying beeswax, dust, and the heavy animal scent of something awake in the dark.

My body reacts before my mind does.

The muscles low in my back tighten. My breath catches. A feeling that is neither fear nor surprise runs over my skin like remembered heat.

Elara notices.

“He will use scent against you.”

“Scent cannot read thought.”

“No. But he knows what you felt yesterday.”

“There was no yesterday.”

Her gaze falls to my bare thigh where the slit of my executioner’s tunic exposes unmarked skin. She looks at it as if expecting words.

“What?” I demand.

“Nothing.”

I seize her wrist before she can turn away. “You brought me here. You asked the king to send me. Tell me what I am walking into.”

For one breath, the royal astronomer disappears and my little sister returns. Her eyes shine with panic.

“You are walking into a choice you keep making.”

The nearest clock strikes.

All twelve clocks in the execution chamber answer out of sequence.

Elara pulls free and presses the knife into my hand. It is a short bronze crescent built to hook around the base of a horn. Along its spine, the king’s artificers have carved seven small suns. Six are black. The seventh glows.

“Cut the right horn,” she says. “Not the left. The right stores what happened. The left stores what might.”

“And which one holds you?”

She looks toward the labyrinth.

“Both.”

The answer chills me more than the knife.

I strap the weapon to my forearm, test the release catch, and check the three vials at my belt. Sleeping poison. Fire resin. Scent-masking oil. Everything required to kill a creature twice my mass.

The red thread around my wrist feels heavier than all of it.

“How many executioners entered before me?” I ask.

Elara does not answer.

The palace walls shudder.

For an instant, the execution chamber changes. The white plaster becomes red stone. The tall windows vanish behind black columns. I see another version of myself standing where Elara stands now.

She is older.

Her hair is white. Ink symbols cover her arms, throat, and bare legs. One hand rests on the curved horn of a kneeling Minotaur.

The image lasts less than a heartbeat.

Then the white chamber returns.

I draw my knife.

Elara grips my shoulders. “If you find writing on your body, do not assume it commands you. The ink can survive dawn. Consent cannot. Whatever another version of you chose, you must choose again.”

“You speak as if you have given this warning before.”

“I have.”

“How many times?”

The clocks stop.

In the silence, something enormous moves beyond the bronze doors. A cloven hoof meets stone.

Clack.

Another step.

Clack.

The scent reaches me again: warm fur, old cedar, metal heated by the sun. Beneath it lies something impossible.

My own skin.

Not the clean scent of the oils I used this morning. Sweat, ink, and the trace of someone else’s breath at my throat. A scent trail that says I have stood on the other side of those doors and returned.

I look down at the red thread.

The knot has changed.

Elara tied three loops. There are now four.

“What happens at dawn?” I whisper.

“The labyrinth chooses one future and erases seven.”

“From memory.”

“From almost everything.”

“What survives?”

“Red ink. Scent, sometimes. His horns.” Elara’s voice breaks. “And the pain of losing you.”

The bronze doors open wide enough for me to enter.

A corridor curves away beneath two painted suns. The walls are covered in hundreds of handprints, all mine. Some point inward. Some point out. One has been drawn in red pigment so fresh it still runs.

Above it is a symbol I cannot read.

My body can.

Heat rolls through me, followed by grief so sharp I nearly drop the knife.

From the darkness at the corridor’s end, a deep voice says my name.

Not like a challenge.

Like an answer to a prayer that has failed forty-three times.

“Lyssa.”

Elara pushes the royal order into my free hand. SEVER THE HORN. BREAK THE LABYRINTH. SAVE YOUR SISTER.

The letters rearrange before my eyes.

For a blink, they read: DO NOT LET THE KING REACH TOMORROW.

Then the original command returns.

I step across the threshold.

Behind me, Elara says, “Forgive me.”

The bronze doors close before I can ask which version of me she means.

Darkness swallows the corridor. I strip the red thread from my wrist, wind it around the hilt of my blade, and follow the Minotaur’s breathing toward the room where the king’s orders say he sleeps.

At the next dawn, I will remember none of this.

But the beast will remember me.
