Introduction
The Girl Beneath the Sea by Andrew Mayne isn’t your average thriller. This underwater crime drama grips you from the first dive and never lets go. Set in the labyrinthine canals and murky waterways of South Florida, it introduces Sloan McPherson—a single mom, part-time police diver, and full-time survivor—as she’s pulled into a dangerous conspiracy that could cost her everything.
Plot Summary
As an evidence recovery diver for the Lauderdale Shores PD, Sloan McPherson is used to finding things beneath the surface. But when she discovers the body of a murdered woman—someone she once knew—her world turns upside down. Suddenly, Sloan goes from finder to suspect, and the deeper she dives into the case, the more tangled the waters become.
Framed, hunted, and unsure who to trust, Sloan must uncover the truth with the help of an unlikely ally: George Solar, the very DEA agent who once put her uncle behind bars. Together, they follow a trail of corruption, betrayal, and buried secrets—above and below the surface.
