Bittersweet by Miranda Beverly-Whittemore
On scholarship at a prestigious East Coast college, ordinary Mabel Dagmar is surprised to befriend her roommate, the beautiful, wild, blue-blooded Genevra Winslow. Ev invites Mabel to spend the summer at Bittersweet, her cottage on the Vermont estate where her family has been holding court for more than a century; it’s the kind of place where children twirl sparklers across the lawn during cocktail hour. Mabel falls in love with midnight skinny-dipping, the wet dog smell that lingers near the yachts, and the moneyed laughter that carries across the still lake while fireworks burst overhead. Before she knows it, she has everything she’s ever wanted: friendship, a boyfriend, access to wealth, and, most of all, for the first time in her life, the sense that she belongs.
