The screaming started in the east wing.

I knew it was screaming—I'd heard enough of it in my twenty-six years to recognize the particular timbre of terror mixed with rage—but my mind refused to process what it meant. The orchestra had stopped playing. The marble tiles beneath my feet no longer felt like a ballroom floor but like the deck of a ship in a storm, tilting sideways, threatening to pitch me into the sea.

"What on earth—" Mother's voice, thin and reedy, cut through the chaos.

Father's hand clamped around my wrist. "The observatory. Now."

He didn't wait for acknowledgment, simply dragged me through the crowd of guests whose expensive gowns and tailored jackets were already turning into a panicked blur of silk and wool. The pale blue dress I'd worn to this godforsaken party snagged on the corner of a marble table. I heard it tear. Didn't care.

The ballroom doors burst open.

Men poured through like ink into water—rough, armed, moving with the coordinated precision of a crew that had done this before. Pirates. The word landed in my chest like a stone dropped down a well, and I watched it sink, watched the implications ripple outward in ever-widening circles.

Father's grip tightened. He was already pulling me toward the corridor, toward the narrow stairs that led up to the observatory where I'd spent the better part of the evening studying the governor's collection of charts. The good ones. The ones that showed the trade routes Father had been too proud to discuss at dinner.

"Don't look back," he hissed.

I looked back.

A man stood in the center of the ballroom—tall enough that his head seemed to brush the painted ceiling, broad-shouldered in a way that suggested he'd been born for violence. He wore a captain's coat, black as a moonless night, and his hair was dark except for those streaks of silver at the temples that made him look like he'd been struck by lightning and survived it. A jagged scar ran from temple to jaw, white and terrible against sun-darkened skin.

He was the most beautiful thing I'd ever seen, which meant he was the most dangerous.

Our eyes met across the chaos.

His were grey. Storm grey. The kind of grey that suggested he'd seen the worst humanity had to offer and decided it was beneath him. There was no malice in his expression—that would have been easier to process. Instead, there was only calculation, cold and precise as a compass needle finding north.

Father wrenched me away.

We made it to the stairs. He shoved me ahead of him, his fingers bruising my wrist, and I took them two at a time, my ridiculous slippers skidding on the marble. The torn hem of my dress tangled between my legs. I kicked it free with a grunt that was decidedly unladylike.

The observatory door was heavy oak, reinforced with iron bands. Father slammed it shut behind us and threw the bolt. His hands were shaking. I'd never seen his hands shake before.

"The documents," he breathed. "They're after the naval documents."

Of course they were.

The observatory was circular, ringed with windows that looked out over the harbor. Maps covered every surface—charts of the coastline, navigation tables, trade routes marked in careful ink. And there, on the desk near the telescope, were the documents Father had been too loose-tongued about at dinner. The ones that showed where our supply ships would be traveling for the next six months. The ones that, in the wrong hands, could cost the Navy a fortune in lost cargo.

In the right hands, could make a man very, very rich.

I moved to the window and looked down at the harbor. A ship sat anchored there, dark and sleek as a shark. The Serpent's Oath, if the hull markings were any indication. I knew that name. Every navigator knew that name. Captain Nathaniel Voss. The man who'd taken three merchant vessels last year. The man who'd disappeared into the Caribbean and emerged six months later with enough gold to buy a small nation.

The man whose eyes had just met mine across a ballroom full of screaming guests.

"Charlotte, step away from the window," Father commanded.

I didn't. Instead, I moved to the desk and began gathering the charts—my charts, the ones I'd spent the last hour studying, the ones that showed the trade routes in exquisite detail. My hands moved of their own accord, rolling them, securing them with the silk ribbons I always kept in my pockets. A habit born of necessity. A habit that was about to save my life or end it.

"What are you doing?" Father's voice had taken on a note of hysteria I'd never heard before.

"Surviving," I said.

The door didn't burst open so much as splinter.

The man from the ballroom stepped through it like he owned the room—which, I supposed, he did now. Behind him came two other men, both armed, both looking distinctly uncomfortable with the fact that they'd just had to break down a door to reach us. Their captain, however, looked utterly at ease. He looked like he'd been born in moments of violence and had simply never bothered to leave.

Up close, he was worse. Better. Some combination of the two that made my skin feel too tight.

"Admiral Ashford," the captain said. His voice was smooth as whiskey and twice as dangerous. "I'm Captain Nathaniel Voss. I'm here to relieve you of some documents."

Father positioned himself in front of me. For a moment—just a moment—I felt something like gratitude toward him. It passed quickly, replaced by the familiar ache of knowing that his protection was born of possession, not affection. I was his asset. His daughter. His responsibility.

"They're not here," Father said flatly.

It was a lie. A transparent one. The documents were in his coat pocket; I could see the corner of the envelope from where I stood.

Captain Voss smiled. It was not a kind smile.

"You're going to want to reconsider that answer, Admiral. I'm not known for my patience, and I've already had to interrupt a rather tedious party to get here. The documents. Now."

Father's hand moved toward the pocket. Toward the envelope. Toward surrender.

I moved first.

I don't know what I was thinking—actually, I know exactly what I was thinking, which was nothing, which was only instinct and survival and the bone-deep certainty that whatever happened next would be better if I had agency in it. I'd spent my entire life being moved around like a chess piece on a board, and I was done.

I threw the bundle of charts at Captain Voss.

They unfurled mid-air, spreading like wings, and he caught them with reflexive ease. His eyes—those terrible, beautiful grey eyes—snapped to mine, and for a fraction of a second, I saw surprise there. Genuine surprise. As if he'd expected many things from the Admiral's daughter, but defiance had not been one of them.

"Charlotte, you fool—" Father started.

"Those are mine," I said, gesturing at the charts now held loosely in Voss's capable hands. "The navigation studies I've been conducting. Not the Navy documents. Mine."

Voss looked down at the charts, then back at me. His scar seemed to deepen as his expression shifted, became something more predatory. "You're a cartographer."

"A navigator," I corrected, my heart hammering so hard I thought it might break my ribs. "And if you're intelligent—which you clearly are, or you wouldn't have gotten this far—you know that the Navy documents are useless without someone who can read them properly. Someone who understands not just the routes, but the timing, the currents, the seasonal variations that make the difference between a successful raid and a failed one."

Father made a sound like a wounded animal.

I kept my eyes on Voss. Kept my chin level. Kept my voice steady even as my hands trembled so badly I had to curl them into fists.

"The documents show where the ships will be," I continued. "But my charts show how to reach them. When to reach them. Where the currents will slow them down, where the shallows will ground them. I spent two years mapping the trade routes for the Navy. Two years of careful observation and precise measurement."

"Charlotte—" Father's voice was a warning.

"She's right," Voss said softly.

He was looking at me the way a man looks at a map that shows him something he didn't know existed. Like I'd suddenly become infinitely more valuable. Like I'd just redrawn the borders of his entire world.

"The documents alone would be worth perhaps fifty thousand pounds to the right buyer," he continued, his eyes never leaving mine. "But a navigator who knows these waters? Who understands the patterns?" He smiled again, and this time it was almost genuine. "That's worth considerably more."

"I'm not for sale," I said.

"Everyone's for sale, sweetheart. The only question is the price."

He said it without malice, which somehow made it worse. It was simply fact, to him. The way gravity was fact. The way death was fact.

"I'm not," I repeated.

Father lunged for the documents. One of Voss's men—the blonde one with the deceptively gentle face—moved with casual efficiency to intercept him. There was a sound like a melon being struck, and Father dropped.

I didn't scream. I wanted to. Every civilized instinct I'd been trained into screamed at me to fall to my knees, to beg, to perform the role of frightened daughter. Instead, I stepped over Father's unconscious form and looked directly at Captain Voss.

"That was unnecessary," I said coolly. "He was already beaten."

Something flickered across Voss's face—amusement, perhaps, or respect. "You're not going to cry."

"No."

"You're not going to beg."

"No."

"You're not going to faint."

"I'm a navigator, not a parlor maid," I said. "Fainting is inefficient."

This time, when he smiled, it was genuine. It transformed his entire face, made him look younger and infinitely more dangerous. "What's your name?"

"Charlotte Ashford."

"Well, Charlotte Ashford," he said, moving toward me with the fluid grace of a predator, "you've just made yourself considerably more interesting than you were five minutes ago."

He was close now. Close enough that I could smell him—tobacco and sea spray and something expensive and dark, like sandalwood left in the sun. Close enough that I could see the individual scars on his face, the ones that spoke of violence survived. Close enough that my body betrayed my mind by noticing the breadth of his shoulders, the strength in his hands, the way his grey eyes seemed to contain entire storms.

I didn't step back.

"I assume you're taking me hostage," I said, pleased that my voice didn't shake. "The Admiral's daughter should fetch a reasonable ransom. Though I should warn you, my father is far more concerned with his reputation than my welfare, so you may find yourself disappointed."

"I'm not taking you for ransom," he said.

He reached out, and I tensed, every muscle in my body coiling like a spring. But his hand only lifted the strand of hair that had escaped my pins, letting it slide through his fingers with a gentleness that seemed impossible given the violence radiating from him.

"I'm taking you because you're useful," he continued, his voice low enough that only I could hear it. "And because I've never met a woman who looked at me like she was calculating my exact weak points and deciding whether they were worth exploiting."

"I'm not looking at you like that," I said.

"You absolutely are." His hand dropped, and I realized I'd been holding my breath. "The question is whether you're brave enough to follow through on the promise in those eyes, or if you're just another pretty thing in an expensive dress who talks a good game."

"I suppose you'll find out," I said.

He turned to the blonde man. "Take the Admiral to the cellar with the others. He'll be useful for negotiations, even if his daughter isn't concerned about his welfare."

Then he looked back at me, and I felt the world shift on its axis.

"You're coming with me, Charlotte Ashford. And if you're very, very good, I might let you live long enough to see what happens next."

He held out his hand.

I should have refused it. I should have fought, screamed, done any of the thousand things a proper young lady would do when being dragged into captivity by a man who'd just admitted to kidnapping. Instead, I looked at his extended palm, at the calluses that spoke of years at sea, at the blood beneath one fingernail that suggested he'd been in a fight before arriving at the party.

I took his hand.

His fingers closed around mine with possessive certainty, and he pulled me toward the door. The contact burned. Literally burned, as if his skin was several degrees hotter than mine, as if he was radiating some kind of internal fire that threatened to consume me if I stood too close for too long.

"Don't touch her," the blonde man said sharply, and I realized he was watching us with something that looked disturbingly like jealousy.

Voss didn't even glance at him. "She's mine now, James. Best get used to it."

He said it casually, the way one might claim a piece of cargo. But there was something else underneath the words, something possessive and dangerous that made my pulse quicken in ways that had nothing to do with fear and everything to do with the fact that I was walking toward an unknown future with a man who'd just upended my entire world, and I was terrified to discover that I was more intrigued than horrified.

We descended the stairs together, his hand never loosening on mine, and I caught a glimpse of myself in the hallway mirror—pale blue dress torn at the hem, hair half-fallen from its pins, eyes bright with something that looked disturbingly like excitement.

I looked like a woman who was about to become someone's captive.

I looked like a woman who didn't entirely mind.

The Serpent's Oath waited in the harbor, dark and sleek and promising, and I was about to step aboard it with a man who smelled like danger and tasted like possibility, and somewhere deep in my chest, in the place where I'd buried all my desperate, dangerous wants, something began to wake up.
