Flowers in the Attic was the mother's betrayal. Petals on the Wind is the daughters revenge.

Chris, Cathy and Carrie have escaped their attic prison and set off with money scavenged from the Grandmother's mansion. Two teenagers and an eight-year-old who haven't seen the outdoors for over three years, determined to stay together, determined to survive. And they are fortunate. They are taken in by a lonely, kindly doctor, who readily shares with them his home, his love, his fortune. But even as the three children build bright new lives, the dark horrors of the attic haunt them.

Cathy is reminded daily by the way her brother watches her, by the way Carrie's tiny, tiny body does not grow. And Cathy is also reminded of the other child, who didn't survive the long years in the attic. Then she thinks of her mother, of her mother's brutal betrayal of those who loved and needed her most. And she vows vengeance.

While Chris pursues his dream of becoming a doctor, even while Cathy becomes a successful ballerina, she dedicates herself to her plans for revenge. And as her plans become obsession, Cathy risks everything to pay her mother back, and to show her what it's like to suffer at the hands of the one you love most.
