The symbol is back.
Isla Hale survived Blackwater Cove, but survival only made her a target. Across distant coastlines, isolated towns are marked-lives erased, histories rewritten, and entire communities quietly dismantled.
Off-grid and hunted, Isla must infiltrate the machinery of the Collective again. Every step is a calculated risk, every ally a potential betrayer. And when the line between predator and prey disappears, Isla is forced to decide how far she’s willing to go-and what she’s willing to sacrifice-to stop a system that can reach anywhere, kill anyone, and rewrite the world.
Dark, relentless, and psychologically intense, Marked by the Tide will pull you into a global conspiracy where no one is safe, and the tide is only just beginning.
