In every glossy picture of the American society pages, there’s an Ev Winslow. Disarmingly beautiful, and - naturally - tall, athletic, with a smile that’s perfect. Small-town Mabel Dagmar has never known anyone like Ev, and now she’s sharing her college dorm - even if she is completely ignored. But suddenly they’re friends and Mabel can hardly believe her luck when she finds herself summering at the Winslow family’s luxurious estate, Winloch, in Vermont.
Winloch is like a small village, with each of the perfect Winslow children inhabiting a pretty white cottage. Days spent swimming in watery coves evaporate into nights at glamorous cocktail parties where Mabel sits alongside the scions and the fountainhead of this prestigious family. And as the formality melts away with one particular Winslow brother, Mabel is left to think that her summer has all but become a golden dream. But when Mabel meets a disgruntled member of the family, she can’t help looking a little closer at the Winslows, probing beneath their glossy exterior. And what she uncovers in their past is almost as shocking as what she finds out about their present. Beneath the beauty is a rotten core. And not everyone is quite as they seem.
