Twenty-six-year-old Evelyn Beegan intended to free herself from the influence of her social-climbing mother, who propelled her through prep school and onto New York’s stately Upper East Side. Evelyn has long felt like an outsider to her privileged peers, but when she lands a job at a social-network startup aimed at the elite, she has no choice but to infiltrate their world. Soon she finds herself navigating the promised land of Adirondack camps, Hamptons beach houses, and, of course, the island of Manhattan itself. Intoxicated by the wealth, access, and influence of her new set, Evelyn can’t help but try to pass as old money herself. But when the lies become more tangled, she grasps with increasing desperation as the ground beneath her begins to give way.
