She studies the ocean's secrets. He guards his own. Together, they'll face a tide that could sweep away humanity.

Dr. Marina Blake is the world's foremost expert on oceanic microbes—brilliant, dedicated, and fiercely protective of the vulnerable coastal communities she serves. When her research uncovers a disturbing pattern of marine anomalies indicating an engineered pathogen in the water, she recognizes the catastrophic global implications. But her warnings fall on deaf ears until catastrophe threatens shorelines worldwide.

Commander Nat Caldwell thought he'd left his nightmares behind when he resigned his naval commission after barely containing a biological weapon incident years ago. Now working maritime security, he's haunted by the lives he couldn't save. When he's assigned to protect the stunning scientist whose discovery could prevent a pandemic, Noah finds himself facing his darkest fears—and an attraction he can't deny.

As Marina and Nat race to identify the source of the engineered contagion, they uncover a sinister plot orchestrated by the Dark Horizon, designed to profit from global chaos. From high-tech laboratories to treacherous ocean depths, their investigation draws them into ever more dangerous waters—and closer to each other. With time running out and dark forces closing in, Marina and Nat must confront not only a pathogen that could devastate humanity, but also the wounds from their pasts that have never truly healed.
