“You’re mad.”

“I know it pleases you to think so,” he said. “But the amplifiers must be brought together. If we have any hope of controlling the Fold—”

“You can’t control the Fold. It has to be destroyed.”

“Careful, Alina,” he said with a slight smile. “I’ve had the same thought about you.” He gestured to Ivan, who was waiting a respectful distance away. “Bring me the boy.”

My heart leapt into my throat. “Wait,” I said. “You told me you wouldn’t hurt him.”

He ignored me. Like a fool, I looked around. As if anyone on this saintsforsaken ship would hear my appeal. Sturmhond stood by the wheel, watching us, his face impassive.

I snatched at the Darkling’s sleeve. “We had a deal. I haven’t done anything. You said—”

The Darkling looked at me with cool quartz eyes, and the words died on my lips.

A moment later, Ivan appeared with Mal in tow and steered him over to the rail. He stood before us, squinting in the sunlight, hands bound. It was the closest we’d been in weeks. Though he looked tired and pale, he appeared unharmed. I saw the question in his wary expression, but I had no answer.

“All right, tracker,” the Darkling said. “Track.”

Mal glanced from the Darkling to me and back again. “Track what? We’re in the middle of the ocean.”

“Alina once told me that you could make rabbits out of rocks. I questioned the crew of the Verrhader myself, and they claim that you’re just as capable at sea. They seemed to think you could make some lucky captain very rich with your expertise.”

Mal frowned. “You want me to hunt whales?”

“No,” said the Darkling. “I want you to hunt the sea whip.”

We stared at him in shock. I almost laughed.

“You’re looking for a dragon?” Mal said incredulously.

“The ice dragon,” said the Darkling. “Rusalye.”

Rusalye. In the stories, the sea whip was a cursed prince, forced to take the form of a sea serpent and guard the frigid waters of the Bone Road. That was Morozova’s second amplifier?

“It’s a fairy tale,” Mal said, voicing my own thoughts. “A children’s story. It doesn’t actually exist.”

“There have been sightings of the sea whip in these waters for years,” said the Darkling.

“Along with mermaids and white selkies. It’s a myth.”

The Darkling arched a brow. “Like the stag?”

Mal glanced at me. I gave an infinitesimal shake of my head. Whatever the Darkling was doing, we weren’t going to help.

Mal peered out at the waves. “I wouldn’t even know where to start.”

“For her sake, I hope that’s not true.” The Darkling pulled a slender knife from the folds of his kefta. “Because every day we don’t find the sea whip, I’ll peel away a piece of her skin. Slowly. Then Ivan will heal her, and the next day, we’ll do it all over again.”

I felt the blood drain from my face.

“You won’t hurt her,” Mal said, but I could hear the fear in his voice.
