A man living on a Florida barrier island must protect his family from both an approaching hurricane and a relentless killer. Jake Powell is racing to get off the island as a powerful hurricane approaches. When he finds his best friend Dallas, the building manager, dead from a blow to the skull, Jake realizes there's more than the storm to fear. There's a murderer on the island, maybe even still inside the nearly abandoned building. Dallas had repeatedly run afoul of the wealthy owners of the building by complaining about code violations and the precarious state of the condos. But he'd also once told Jake that every resident had a secret they'd come to Florida to escape. Had one of them killed to conceal their sins? As a dozen people shelter together in hopes of surviving the deadly hurricane, a second murder makes it all too clear: one of them is a dangerous killer.
