Hush (2002)

After Toswiah Green's father testifies against a fellow police officer in a murder case, the Greens are forced to enter the Witness Protection Program and give up all traces of their past. For Toswiah—now Evie Thomas—her new life is completely different. Her defeated father spends his days sitting by the window, all her mother's energy goes to their new church, and her only sister is making secret plans to leave. Evie is left wondering who she is and how she can make her future as bright as her past once was.
