The East End continues its status as a literary gold mine with hot new titles. Emma Cline’s “The Guest” follows a twentysomething’s shenanigans as a fish out of water navigating the Hamptons’ social scene. When she wasn’t busy hosting “The View,” Sunny Hostin penned “Summer on Sag Harbor” about a woman who mysteriously inherits a home in the idyllic hamlet.
