In a quiet coastal town where everyone knows everyone, Y/n—the golden girl of Seabrook Cove—lives a life built on routine, community, and the ocean. But everything shifts when her neighbor Molly remarries and a new family moves in next door. Among them is a closed-off teenage boy who wants nothing to do with the town—or its people. As their worlds start to collide, Y/n is pulled into something unfamiliar, where first impressions aren’t what they seem and nothing in Seabrook stays simple for long.
