Twelve months ago, a violent injury ended Kate Park’s career with the Florida Fish and Wildlife Commission. Now she’s returning home to her little beach town and teaching boat safety classes while her body heals. Maybe she’ll even mend the estranged relationship with her caustic younger sister. But time is running out.

As the Florida West Coast braces for an approaching Category 4 hurricane, Kate uncovers a corpse in the churning Gulf waters. Then another. And another. It’s no longer her job to get involved, but she can’t help investigating. And the clues reveal all three victims have one thing in common: a connection to her sister.

In a brewing storm of rage, guilt, and family secrets, she confronts her bitter sibling and faces a childhood better left buried with the bodies washing ashore. To unravel the threads of this mystery is to come to a frightful realization.

Someone she knows is watching.

Someone she knows is stalking.

And something hides in the darkness.
