The Shoreless Beacon

Hundreds of miles from any ocean, a lighthouse stands where no lighthouse should exist. Every night, without explanation, its lamp still turns. And every night, the beam catches the outline of someone who should not still be there. When three young investigators are drawn to the impossible structure, they uncover a chain of vanished records, a town that insists the lighthouse was never built, and a light that seems to be waiting for something to come back.
Featuring investigators Ethan Blackwell, Mara Whitlock, and Daniel Cross, this is the first case in a series built on quiet dread, buried history, and mysteries that refuse to stay buried.
