Letting Go Of Bobby James, or How I Found Myself of Steam by Valerie Hobbs
Jody sets out at 16 with her husband Bobby James. They don't really have a plan, just kind of drifting. And then he hauls off and smacks her hard across her face. While she is in a gas station bathroom, he abandons her. This is the story how Jody makes a life without him, and finds herself in the process.
Not a gruesome book, considering the subject matter. But the book didn't dig at all. You never really feel like you get to now Jody or her new set of friends.
