The Girl Death left Behind by Lurlene McDaniel

In one afternoon, Beth's entire world is torn away from her. When a car accident claims the life of every other member of her family, Beth wishes she were dead too. She feels sure her situation could not get worse-but then she must leave the home she knows and live in another state with her aunt and her spoiled cousin, Terri. 

Starting a new life isn't easy, especially in Terri's clique-filled school. With the help of some unexpected allies and the persistent concern of her aunt and the friends who have always loved her, Beth defies the despair that threatens to engulf her. Still, she can't bring herself to let go of her painful memories. How can she move on, yet not feel guilty about being a survivor?
