Prologue

Launch Minus Four Minutes

The Moon moved three centimeters while Leo Mercer was signing the waiver.

No one else in the launch chamber noticed.

Technicians sealed his black flight jacket. Cameras drifted around him in silent formation, projecting his face to three billion viewers. General Vance stood beyond the glass with both hands clasped behind his back, wearing the expression of a man who had already converted Leo’s death into recruitment material.

Leo watched the orbital figures crawl across his wrist display.

Three centimeters toward Earth.

The number was small enough to hide inside a rounding error. It was also impossible. The Crown Circuit’s gravity engine was supposed to remain dormant until a match produced a legal victor.

“Pilot Mercer,” the broadcast host announced, “humanity’s claim to the Moon now rests in your hands.”

Leo smiled for the cameras.

His hands had failed people before.

Seven years earlier, a training collision had torn his squadron in two. Leo had saved the experimental engine sample strapped behind his seat because Command said its telemetry could prevent a war. He had left two pilots spinning without thrust.

The sample survived.

They did not.

Now that same engine design powered the arena circling the Moon.

“Telemetry discrepancy,” Leo said quietly.

The technician at his shoulder did not look at the display. “Within tolerance.”

“It shouldn’t have a tolerance. The turbine is cold.”

“The League certified it.”

That ended the discussion.

Across the launch chamber, a second blast shield cleared.

Varessa Korr entered the Orathi airlock.

The Champion wore no suit because the ivory armor covering her was alive. Plates shifted over muscle in smooth, overlapping currents. Two violet gravity fins ran from her back toward her hips, gathering static from the room. Her long magnetic tail anchored to the deck behind her.

Four golden eyes found Leo through two layers of glass.

The lower pair measured distance.

The upper pair measured him.

Every image of Varessa in the human briefings showed her victorious. Kneeling opponents. Broken arena pylons. The white flare of her gravity field forcing another body to accept her definition of down. None showed the civilian convoy she had dragged through a radiation storm to deny an enemy fleet its prize.

Heroes were easier to sell after the casualties had been cropped away.

Leo raised two fingers to the glass.

Varessa did not return the gesture.

She placed one palm over the center of her armor, where her two hearts beat out of phase.

The Orathi crowd feed exploded with light.

“She’s invoking the vector oath,” the translator told Leo. “The victor may claim directional authority from the defeated.”

“Meaning?”

“If she wins, she controls which way you fall.”

“For how long?”

The translator hesitated. “Long enough.”

Vance’s voice entered Leo’s private channel. “Do not accept any voluntary transfer.”

“It’s part of the match.”

“Then make sure she loses before it matters.”

The blast shield clouded again.

Leo looked at the Moon through the outer hull. The lunar surface had become territory in a dispute neither side could afford to lose. Five matches. Five transfers of engine authority. A clean, civilized alternative to war.

Except the Moon had already moved.

He opened a maintenance window beneath the waiver.

The turbine showed a charge.

Not much. A fraction gathered from the rehearsal cycles, crowd calibration and ceremonial oaths. But the energy was not stored in the arena batteries. It was routing into a sealed League manifold beneath the lunar crust.

Leo copied the trace.

The file disappeared.

He tried again.

This time his display locked.

“Launch readiness confirmed,” the chamber announced.

Magnetic clamps closed around his boots. The floor rotated vertical, aligning him with the transparent mouth of the arena rail. Beyond it waited vacuum, the Moon and the alien woman humanity required him to defeat.

Varessa’s launch chamber rotated opposite his.

For one second they hung face-to-face across open space.

Her four eyes narrowed.

Then she tapped one claw against her chest, twice fast and once slow.

Leo’s translator supplied no meaning.

His engine did.

The rhythm matched the unauthorized pulse entering the lunar manifold.

She knew.

The official biographies said Varessa had never hesitated in an arena. Leo could see the lie in the minute shift of her gravity fins. She was not afraid of fighting him. She was measuring whether the stranger across the launch gap had found the same trap that had kept her winning for eleven years. If either of them broke formation now, their governments would replace them before the opening broadcast finished. Their only private conversation would have to look exactly like combat.

Neither champion could expose the machine until both had survived long enough to understand it.

The audience began counting down.

Ten.

Leo unlocked his right wrist thruster and opened a manual channel.

“Champion,” he said. “If you can hear me, the engine is charging before the first match.”

Varessa’s tail tightened around the launch rail.

Nine.

“Someone built the result before we arrived.”

Eight.

Her upper eyes moved toward the Moon. The lower pair remained on him.

Seven.

The gravity fins along her back opened in a wash of violet light.

Six.

“Fight me,” Leo said, “but watch where the energy goes.”

Five.

Varessa placed her palm against the glass.

Four.

Leo matched it from his side.

Three.

The turbine beneath the Moon answered both heartbeats.

Two.

The launch shields vanished.

One.

The carbon-weave tether snapped with a vibration that rattled Leo Mercer’s teeth.
