The ship went down in seventeen minutes.

I counted. Seventeen minutes, start to finish. It helps me remember that destruction is mathematics, not murder. Waves at the right angle, pressure applied to the correct stress points, and wood becomes splinters. Sailors become bodies. A Fire Kingdom warship becomes debris floating on my ocean.

My ocean. That's what Father calls it. The Stormborn Sea belongs to me the way a sword belongs to a soldier.

I am the sword.

The last of the flames guttered out as the waves swallowed the stern. Fire couldn't burn underwater, no matter how hard the Fire Kingdom mages tried. Their power flickered and died, and so did they.

I stood on the cliff above the wreckage, salt wind whipping my hair against my cheeks. My hands were still wet. Not from the sea spray, from the magic. When I call the water, it answers through my skin, rising up from some deep well inside my chest and flowing outward. After a working this large, moisture clings to me like a second layer of flesh.

"Your Highness." Captain Roth approached from behind, his boots crunching on gravel. "The council has been summoned. Your father expects you."

"I know." I didn't turn around. Below me, a body rolled in the surf. Too far to see the face. Good. "How many survivors?"

"None confirmed."

None. Forty-three sailors, based on the ship's class. Forty-three Fire Kingdom citizens who woke this morning expecting to return home.

The water in my chest ran cold. It ran cold after every working like this.

"Their prince's brother was aboard."

I turned then. Captain Roth's weathered face showed nothing, he'd served my father for thirty years and learned to keep his expressions locked away, but his voice carried a weight that made the cold spread.

"Which brother?"

"Pyrus. The younger one."

Pyrus. I'd heard the name in intelligence briefings. Second in line to the Fire Throne, barely twenty years old, known for diplomacy rather than combat. He'd argued for peace in their council, or so our spies claimed.

And I'd just drowned him.

"He was on a warship in our waters," I said. The words tasted like salt. "He knew the risks."

"Yes, Your Highness."

I started walking toward the palace. The cliff path was familiar enough that my feet found the way without my eyes. "Tell the council I'll be there within the hour. I need to change."

I needed to wash the ocean off my hands.

The Storm Palace had been carved from the cliffs themselves, grey stone polished by centuries of wind and rain. It was beautiful in the way knives were beautiful: all clean lines and sharp edges, built for purpose rather than comfort.

I'd been born here. I would likely die here. In between, I served.

The servants didn't speak as they helped me out of my salt-stiffened clothes and into formal court attire. Silver-blue silk, the color of shallow water. A circlet of pearl and moonstone. Soft slippers that made no sound on the stone floors.

I looked like a princess. I felt like a weapon someone had cleaned and returned to its sheath.

The council chamber occupied the heart of the palace, a circular room with a domed ceiling painted to look like a stormy sky. My father sat at the head of the long table, his silver hair pulled back from a face that had stopped showing emotion decades ago.

King Maren Stormhold. Conqueror of the Coral Isles. Architect of three successful naval campaigns. The man who taught me to count when I killed.

"Tempest." He didn't rise. "Sit. We have much to discuss."

I took my place at his right hand, where I always sat. The council members were already present: Admiral Crest, her grey hair braided with shells; Lord Tidefall, fat and nervous, sweating despite the cool air; Lady Deepwater, ancient and sharp-eyed, who'd been advising kings before my father was born.

And one stranger.

He stood at the far end of the table, and everything about him was wrong. His clothes were crimson and gold, the colors of fire. His skin held the warm brown tone of the southern kingdoms. His hair was the color of copper, and his eyes,

He watched me the way a blade watches its target, and the temperature in the room climbed.

"Princess Tempest," my father said, "may I present Prince Cinder of the Fire Kingdom. He arrived an hour ago, under flag of truce, with... urgent news." An hour ago. His brother had been dead for less than a day, and Cinder had already sailed into enemy waters. Whatever drove him here was stronger than grief.

Cinder. The Crown Prince. Heir to the Fire Throne.

The older brother of the man I'd just killed.

He stepped forward, and I noticed his hands. They weren't just warm, they were smoking. Thin wisps of vapor rose from his knuckles, and the air around him shimmered with contained heat.

"Your Highness." The word sounded like a curse in his mouth. "Your hands are still wet."

I looked down. He was right. Despite the change of clothes, despite the servants' attention, moisture still clung to my fingers. The ocean never fully released me after a large working.

"Your hands are still smoking," I replied. My voice came out steadier than I felt. "Are we here to discuss our grooming habits, or is there a purpose to this meeting?"

His chin lifted. Not quite surprise, more like a predator reassessing its prey.

"My brother is dead because of you."

"Your brother was on a warship invading my waters. The ocean does not forgive trespassers, and neither do I."

The heat in the room spiked. I felt sweat prick at my hairline, but I kept still. Stillness was a weapon too.

"Enough." My father's voice cracked through the tension like a whip. "Prince Cinder did not come to wage war. He came to propose an alliance."

I blinked. Whatever I'd expected, it wasn't that.

"An alliance," I repeated. "With the nation that's been trying to burn our fleet for three generations?"

"With the nation that's dying." Cinder's voice was rough, like he'd been screaming recently. Or crying. "Just like yours."

He reached into his coat and withdrew a sealed scroll. When he tossed it onto the table, I caught the scent of something wrong. Sweet and rotting, like fruit left too long in the sun.

"Open it," he said. "If you can."

Lord Tidefall reached for the scroll. The moment his fingers touched the seal, he jerked back with a cry. Purple-black marks spread across his palm, crawling up his wrist like hungry vines.

"What is this?" Admiral Crest demanded, rising to her feet.

"The plague." Cinder's hands had stopped smoking. He looked tired now, the anger burning down to something colder. "It's been spreading through my kingdom for three months. Started in the villages, moved to the cities. We've lost eight thousand people. No fire can burn it. No healer can cure it."

Lady Deepwater made a sharp gesture, and a servant hurried forward with a cloth to wrap Lord Tidefall's hand. Already, the marks were fading, he'd only touched it briefly, but his face had gone grey.

"Why come to us?" I asked. "Why not seal your borders, burn the infected, protect what remains?"

"Because we've tried." Cinder looked at me, and I saw something beneath the hatred. Fear. Real, bone-deep fear. "It doesn't burn. It can't be quarantined. And three days ago, it appeared in your kingdom too."

The water in my chest turned to ice.

"That's impossible. We would know..."

"The fishing village of Saltmere." My father's voice was heavy. "We received reports this morning. Fourteen dead. The bodies showed the same marks."

I gripped the edge of the table. The wood was cold and solid, an anchor in a world that had just tilted sideways.

"The plague is magical," Cinder continued. "Our scholars finally determined its nature. It feeds on elemental power. Fire. Water. The very things that make our kingdoms strong."

"Then we need to stop using magic..."

"That's not how it works." He stepped closer, close enough that I could feel the heat rolling off him in waves. "It doesn't just feed on active magic. It feeds on the potential for magic. Everyone with elemental blood is a target. And the strongest..."

He looked at me. Then at himself.

"The strongest are the most delicious."

Admiral Crest slammed her palm on the table. "Why should we believe any of this? You could be lying, trying to..."

"Trying to what?" Cinder laughed, and there was no humor in it. "Trick you into an alliance that would destroy a war we were winning? Fake a plague that's killing my own people?" He pulled up his sleeve, and I saw the marks. Faint, but present. Purple-black threads crawling beneath his skin. "I'm already infected. So, probably, is your princess. The plague takes the strongest first."

The room erupted into chaos. Council members shouting, my father demanding order, Admiral Crest calling for healers. But I sat frozen, staring at the marks on Cinder's arm.

Feeling, for the first time, a faint itch beneath my own skin.

"There's only one cure," Cinder said, and his voice cut through the noise like a blade through water. "The scholars found it in an ancient text. A prophecy, if you believe in such things."

"What cure?" My father's voice was dangerously quiet.

Cinder looked at me. Really looked, not with hatred this time, but with something worse. Resignation.

"Fire and water," he said. "United. Not just allied, united. The prophecy says combined elemental magic is the only thing that can stop this plague."

"Combined elemental magic is impossible," Lady Deepwater said. "Fire and water cannot merge. They destroy each other."

"Not impossible." Cinder reached into his coat again and pulled out another scroll, this one older, the parchment yellowed with age. "Rare. Difficult. But not impossible. It's been done once before, a thousand years ago. There's a ritual. A binding."

He looked at me again.

"A marriage."

The word hung in the air like smoke.

"No." I was on my feet before I realized I'd moved. "Absolutely not. I just killed your brother. You hate me. I..."

"I don't care about hate." Cinder's voice was flat. "I care about survival. Yours and mine. If the plague isn't stopped, there won't be a Fire Kingdom or a Storm Kingdom left to fight over. Is your pride worth more than every life in both nations?"

My father stood slowly. His face was unreadable, but I knew that look. He was calculating, weighing options, determining strategy.

"We will need time to verify these claims," he said. "To examine the texts, consult our own scholars..."

"Time is the one thing we don't have." Cinder pulled his sleeve down, covering the marks. "I came here expecting you to refuse. I came here expecting to die, honestly, given what your daughter did this morning. But I came anyway, because I'm out of options. We both are."

He turned toward the door, then paused.

"The plague will take the strongest first. The royals with the most powerful magic. You, Princess. Your father. Then it spreads outward, feeding on everyone with even a drop of elemental blood in their veins." He glanced back over his shoulder. "You have three days to decide. After that, I doubt either of us will be alive to argue."

He walked out.

The door closed behind him. The silence that followed was absolute.

I looked down at my hands. Still wet. Still cold.

For the first time in my life, I wondered if the ocean might not be enough to protect me.

"Father," I said quietly. "Show me the reports from Saltmere."

He nodded to a servant, who hurried to retrieve a folder. When I opened it, I saw the photographs.

Bodies marked with purple-black threads. Eyes frozen wide with terror. Skin gone grey and cold, all the water stolen from their flesh.

Fourteen people who woke up three days ago expecting to live.

Just like the forty-three sailors on that Fire Kingdom ship.

Just like the brother of the man who'd just asked me to marry him.

The folder fell from my fingers.

"Summon the scholars," I said. "And send word to Prince Cinder. Tell him..."

The water in my chest trembled.

"Tell him I'll listen."
