When Catherine Morrow is admitted to the Esther Percy School for Girls, it's on the condition that she reform her ways. But that's before the charismatic and beautiful Skye Butterfield, daughter of the famous Senator Butterfield, chooses Catherine for her best friend. Skye is a young woman hell-bent on a trajectory of self-destruction, and she doesn't care who is taken down with her. No matter the transgression'a stolen credit card, a cocaine binge, an affair with a teacher, an accident that precipitates the end of Catherine's promising riding career-Catherine can neither resist Skye's spell nor stop her downward spiral.
