Rook & Quinn: The Wickmere Point Signal ebook

On the fogbound coast of Maine, a decommissioned lighthouse at Wickmere Point has stood dark and abandoned for over forty years — until local fishermen start reporting a strange, pulsing light returning to its tower on moonless nights, always just before someone vanishes without a trace. When a marine biologist studying the coastline becomes the third person to disappear in six months, Lucian Rook and Elara Quinn travel to the isolated peninsula to investigate, only to discover that the lighthouse's decommissioning three decades earlier wasn't the accident the town has always believed, and that whatever answers the light with each pulse, someone in Wickmere Point has been protecting it ever since.
