The sea was a bruised purple, the color of a fresh wound. On the island of Oros, a jagged tooth of basalt sticking out of the churning froth of the Middle Sea, Thalassa sat by a tide pool, watching the water dance. She didn’t look at the waves with her eyes; she felt them through the soles of her calloused feet. She felt the heavy, rhythmic thrum of the deep-sea currents and the sharp, erratic twitch of the coming gale.
“Three days,” she whispered to the wind. “The Crest is moving south.”
For five years, Thalassa had been the “Salt-Witch,” an outcast living in a hut made of whalebone and driftwood. Once, she had been the youngest Lead Navigator of the Tyrian Navy, a girl who could guide a fleet through a needle’s eye. Then came the Night of the Red Foam. A storm had appeared out of a clear sky, a wall of water three hundred feet high that had crushed the King’s treasure fleet. Thalassa had survived. Her father, the Admiral, had not. The Council of Elders had needed a scapegoat, and they chose the girl who claimed the sea had “warned” her.
A horn blast—low, mournful, and metallic—shook the air.
Thalassa stood, her long, salt-matted hair whipping around her face. Emerging from the perpetual grey mist of the horizon was a ship. Not a fishing skiff, but a royal trireme, its gilded prow carved in the shape of a leaping dolphin. It was battered, its oars moving in an uneven, exhausted rhythm.
The ship didn’t dock; there were no docks on Oros. It dropped anchor in the lee of the cliff, and a small rowing boat was lowered into the surf.
Thalassa met them on the shingle beach. She held a harpoon of blackened iron, her amber eyes narrowed against the spray. Out of the boat stepped a man in a breastplate of polished bronze, draped in a cloak of Tyrian purple.
“High Admiral Hanno,” Thalassa said, her voice like grinding shells. “You’ve lost your way. The capital is three hundred leagues to the east.”
“I know where I am, Thalassa,” Hanno said. He looked older than she remembered. His beard was white with salt, and his eyes were bloodshot. “And I know what I’ve lost. The King is dead. The Storm-Wall has moved into the Inner Bay. We are losing a city a week to the waves.”
“Then you should be praying to Melqart,” she said, turning back toward her hut. “I am just a witch on a rock.”
“We found the Log of the First Voyagers,” Hanno shouted over the roar of the surf.
Thalassa froze. She turned slowly. “That’s a children’s tale.”
“It’s not,” Hanno said, stepping forward, his boots sinking into the wet sand. “It speaks of the Pillar of the Sun. An amber lens that can vibrate the air to stillness. It’s located on the Isle of Ash, at the center of the Great Maelstrom. But the charts are written in the old cipher—the one your father taught you.”
Thalassa looked at the trireme. She saw the soldiers on the deck, their faces pale with terror. She saw the way the sky was darkening, the clouds swirling into the shape of a funnel. The sea was no longer just water; it was an entity, a hungry god reclaiming the world.
“If I go,” Thalassa said, “I don’t go as your prisoner. I go as the Master of the Ship. Your men take orders from me, or I’ll throw them to the sirens myself.”
Hanno bowed his head, a gesture of total surrender. “The Crest is upon us, Thalassa. Lead us, or we all become salt.”
