David Charleston, once a world‑renowned journalist, now lives in isolation as the keeper of Thunder Rock lighthouse on Lake Michigan, refusing his pay and seeing only the monthly inspector. He imagines conversations with the spirits of a 19th‑century packet ship that sank with sixty passengers, hearing their hopes, fears and stories—a spinster yearning for independence, a doctor exiled for unconventional methods, and his own desperate 1930s pleas about fascism that fell on deaf ears. These imagined dialogues gradually restore his sense of purpose and hope for the future.
