🏗 The Last Lighthouse

Dr. Maeve Calloway inherits a lighthouse on Eilean Gorm, a barren island off the Scottish Highlands, from her estranged grandfather Angus. She discovers that Angus built a listening room in the basalt beneath the lighthouse — a chamber that amplifies whale calls at 52 hertz. His notebook reveals decades of observations suggesting that whales communicate navigational data, weather predictions, and warnings through structured acoustic patterns. When the whales begin broadcasting an unprecedented warning call, Maeve teams up with an oceanographer to decode it — and discovers that the Atlantic ocean current system is collapsing far faster than anyone predicted. The story also reveals that the lighthouse sits atop a 5,000-year-old Neolithic listening station, part of a network spanning the North Atlantic.
