Separated by a raging flood and stalked by the last surviving creature on the island, Phair and young Mia fight to stay alive as the storm becomes both their greatest enemy and their only shield. But as the thunder fades, so does their cover—leaving them exposed at the very moment Mia’s brother’s cries give the monster its next target.

Meanwhile, Chief Fry faces the impossible: a ruined bridge, a stranded family, and monsters massing just across the gap. His desperate mission to protect what’s left of civilization ignites a chain of events that will echo straight into Phair’s fight for survival.
