Summer is coming to a close on the East End of Long Island, and Alex is no longer welcome. A misstep at a dinner party, and the older man she´s been staying with dismisses her with a ride to the train station and a ticket back to the city. With few resources and a waterlogged phone, but gifted with an ability to navigate the desires of others, Alex stays on Long Island and drifts like a ghost through the hedged lanes, gated driveways, and sun-blasted dunes of a rarefied world that is, at first, closed to her. Propelled by desperation and a mutable sense of morality, she spends the week leading up to Labor Day moving from one place to the next, a cipher leaving destruction in her wake.
