Maren Dacosta has one plan: finish her night shifts at the harbor diner, save just enough, and leave storm-lashed Bahia Loreto. Everything changes when a rusted locker from the long-missing research vessel Wild Dream washes ashore with her name etched inside. The catch? Maren has never set foot on a ship, and the only person who might have known why—her oceanographer mother—vanished the same summer the Wild Dream did. Inside the locker are a barnacled sextant, a hand-inked chart of impossible constellations, and a note: 'Find the quiet reef before they do.'
Following salt-stiff coordinates, Maren signs onto the salvage tug Halcyon, captained by Soren Keating, a man with a talent for looking away. His backers—the Keating siblings of Seaforth Consortium—want the Wild Dream for different reasons. Dr. Isla thinks the wreck hides proof of fraud; Finn treats the hunt like sport; careful Theo counts risks; Rowan never lets Maren out of her sight. As motives collide, riddles stitched into tide tables, lighthouse logs, and whale-song spectrograms pull Maren into a plot born in the abyss. To live, she must read the ocean's codes, outpace a killer in oilskins, and choose who to trust before the reef goes quiet.
