When Sam and Riley Boyd move to a quiet coastal town in Florida hoping to escape grief and start over, they think they've found the perfect fixer-upper by the sea. But Driftwood Lane has secrets—ancient ones buried beneath brackish water, sealed behind attic doors, and whispered through salt-drenched walls.

As Riley slips into sleepwalking trances and speaks in forgotten tongues, Sam discovers a haunting legend: a sea witch once drowned by the townsfolk, cursed to return every ninth tide to claim a new vessel. And this time, she's chosen Riley.

The tides are rising. Time is vanishing. And the house is watching.

To save his wife, Sam must uncover the truth behind the ritual—and make a sacrifice the sea won't refuse.

The ocean doesn't forget. And it never gives back what it takes without a cost.
