Left Behind in Blue Water: The Unthinkable Disappearance of Tom and Eileen Lonergan on the Great Barrier ReefOn a bright January day in 1998, American couple Tom and Eileen Lonergan stepped onto a dive boat in Cairns, Australia, bound for the shimmering beauty of the Great Barrier Reef. They logged their tanks, checked their gear, and entered the water with dozens of other divers.The boat came back without them.By the time anyone realized the mistake, the Lonergans had been adrift for nearly two days in open ocean. What followed was a frantic search, a trail of haunting clues-including a dive slate that read "Please help us... we have been abandoned"-and a criminal case that shook Australia's dive industry to its core.Left Behind in Blue Water is a deeply researched, human-centered account of one of the most haunting maritime tragedies of modern times.
