In the misty coastal town of Halewick, Evelyn Gray searches for her missing brother, Thomas, whose disappearance is tied to the town’s old lighthouse. With Detective Samuel Crowe, she uncovers haunting links between her brother and Crowe’s long-dead sister. Beneath the lighthouse lies a hidden cave where the sea itself seems alive calling to the living through the voices of the lost. When Evelyn realizes her brother’s spirit is trapped, she sacrifices herself to silence the curse. But the sea, ancient and insatiable, never truly sleeps. Each generation, it hungers again for another to fall prey.
