Poppy, Lily, and Belladonna would do anything to protect their best friend, Raven. When they discovered he was suffering abuse at the hands of his stepmother, they came up with a lethal plan: petals of poppy, belladonna, and lily in her evening tea so she'd never be able to hurt Raven again. But someone got cold feet, and the group fell apart. Three years later, on the eve of Raven's seventeenth birthday, his stepmother turns up dead. When belladonna is found in her tea, it's only Belladonna who is carted off to jail. Belle reaches out to her estranged friends to prove her innocence. Soon everyone has something to lose... and something equally dangerous to hide.
