Stranded on an Island That Isn't on Any Map. Every Night, It Moves.

About the story

The research ship Gull's Promise was three weeks out from port, mapping coral reefs in the Sapphire Reach, when the storm came out of a clear sky. Lightning. Waves like walls. A crack like the world splitting, and then cold water and darkness. You wake up on a white beach with sand in your mouth and the sun in your eyes. You're alive. So are three others: the ship's captain, Freya Thornquist, who's sprained her ankle and is furious about it; Dr. Priya Raman, the expedition's marine biologist, who saved her notebooks before she saved her shoes; and Bastian Kroll, the ship's cocky deckhand and cook, who is already building a fire and singing about it. The rest of the crew got away in the lifeboat before the ship broke up. The Gull's Promise is a wreck on the reef, half sunk, still full of supplies, if you can reach them. The island is beautiful: a jungle of giant ferns, waterfalls, glowing mushrooms, black-rock cliffs, a lagoon of blinding blue and a mountain at its heart wrapped in mist. It isn't on any chart. Captain Thornquist has sailed the Sapphire Reach for twenty years and swears it shouldn't exist. Then you notice the stars. Every night you mark the stars from the beach, and every dawn they're in a different place. The sun rises over the wrong cliff. The compass needle drifts. On the third morning, you watch the coastline of a distant island slide past the horizon, slowly, like a ship. The island is moving. And it isn't an island at all. As Priya will eventually prove, with great excitement and very little sleep, it's a living creature: an islewhale, an ancient, gentle giant so old and so slow that forests have grown on its back. The sailors' legends call it Old Mossback. It's been swimming the oceans for longer than anyone has kept records, and it's heading somewhere. You have twenty-one days. Priya's measurements say that's when Old Mossback will reach the deep waters of the Cradle and dive, as islewhales do, for a hundred-year sleep beneath the sea. When it dives, the island goes with it. Survive. Salvage the wreck. Build a camp, then a real shelter, then a boat. Map the jungle, the caves, the waterfalls and the strange ruins near the summit left by people who once lived on Mossback's back. Find food and fresh water. Keep the crew together through storms, arguments and homesickness. Learn to understand the giant beneath your feet; it may be more aware of you than you think. And watch the horizon: on day twelve, a ship arrives, and its crew aren't rescuers. They're moonpearl hunters, and they want to harvest the glowing pearls that grow in Mossback's shell gardens. Build a raft and sail for the shipping lanes? Signal for rescue? Or find a way to ask an ancient creature for a ride? No gore, no grim deaths. Just a jungle island, a wild sea, a crew of strangers becoming friends, and the biggest secret in the ocean.
