What happens when your best friend suddenly disappears and your life is turned upside down? That same best friend, who knew all your deepest secrets and darkest lies, who had been there through every relationship, every breakup and every mistake?
This is what happened to Aria, Caroline, Maddy and Bella-wrecking their a little less than perfect lives. Stacy Hale, the queen bitch who reigned in New York High, the school of the privileged and the posh. Her perfect posse consisted of the It-Girl Caroline, the jock Maddy, the perfectionist Aria and nothing-special Bella. Their lives were envied by all-before all of Stacy's lies and games came as a hurricane and they all got caught in it. After her disappearance, they struggle to get out of the web of lies, mysteries and secrets Stacy left behind.
Will they find her and get their answers, or will everyone go down with her?
