For a Florida police diver, danger rises to the surface in an adventurous thriller by the Wall Street Journal bestselling author of The Naturalist.
Coming from scandalous Florida treasure hunters and drug smugglers, Sloan McPherson is forging her own path, for herself and for her daughter, out from under her family’s shadow. An auxiliary officer for Lauderdale Shores PD, she’s the go-to diver for evidence recovery. Then Sloan finds a fresh kill floating in a canal—a woman whose murky history collides with Sloan’s. Their troubling ties are making Sloan less a potential witness than a suspect. And her colleagues aren’t the only ones following every move she makes. So is the killer.
Stalked by an assassin, pitted against a ruthless cartel searching for a lost fortune, and under watch within her ranks, Sloan has only one ally: the legendary DEA agent who put Sloan’s uncle behind bars. He knows just how deep corruption runs—and the kind of danger Sloan is in. To stay alive, Sloan must stay one step ahead of her enemies—both known and unknown—and a growing conspiracy designed to pull her under.

For a police diver in Florida, solving a cold-case mystery brings a serial killer out of hiding in a deep, dark thriller by the Wall Street Journal bestselling author of The Naturalist.
Sloan McPherson and the Underwater Investigation Unit have discovered a van at the bottom of a murky Florida pond. Sealed inside the watery tomb are the bodies of four teenagers who disappeared thirty years ago after leaving a rock concert. To authorities, it looks like a tragic accident. To Sloan, it looks like murder. Every piece of evidence is starting to connect to a string of cold case vanishings throughout Florida. Clue by clue, Sloan navigates the warm, dark waters where natural predators feed, knowing that the most dangerous one is still above the surface—nesting and dormant.
But when a fresh young kill is found in the Everglades, Sloan fears that her investigation has reawakened a monster. How can she catch someone who’s a genius at hiding in plain sight? By acting as prey. The dangerous gambit is working—only too well. She’s being lured into a deception of the madman’s own design. Has Sloan set a trap for a serial killer? Or has he set one for her?

When it appears to be the work of an ecoterrorist and other ships are threatened, it becomes a race against time.

Sloan grows concerned that key details are being ignored, and a strange lack of urgency by authorities sets off alarms.
As the troubling questions compound, Sloan is determined to chase down every lead she has. Her persistence is getting her closer to the truth: that there’s something far more troubling at play than the official explanation. It’s also putting Sloan on a collision course with an enemy more powerful than she realizes, in a case so complex and deadly it may be impossible to prove. Now cracking the case is a matter of staying one step ahead of someone with every resource imaginable to bury Sloan and everything she knows.
