But that's before the beautiful and charismatic Skye Butterfield, chooses Catherine for her best friend. Skye is in love with danger and the thrill of taking risks, breaking rules, and crossing boundaries, no matter the stakes. The problem is, the stakes keep getting higher, and Catherine can neither resist Skye nor stop her from taking down everyone around her.

De Gramont's chilling novel is a portrait of adolescent seductions in all their beauty and terror. Caught in a world that is both alluring and astonishing, the girls of Esther Percy are optimistic and willful, loving and selfish, daring and cruel - all the while believing they're utterly indestructible.
