To be honest, I felt the synopsis was misleading. While Hailey is essentially gutter-trash, she doesn't appear to live in the "slums", and while her family does have it's hardships (though the financial issues are largely due to the laziness of the father), and though God is mentioned....she doesn't really look to Him all that much. And while the issue with Moses is the one conflict in the story, he's not even that central of a character.
I know this story is supposed to be dark and gritty, and I suppose for those who haven't been "across the tracks" it truly is. But, I wonder if it's meant more for shock value. There is no real emotion in this book with Hailey. She does certain things for no other reason than because she can, not caring or even seeming to process consequences, about how it would affect others. Several scenes just seemed too impulsive.
I did like the idea behind the story though, and think with a little polishing, this could be a great book. It is "different", in that it's not all sunshine and rainbows. It shows that sometimes, in some people's lives, things aren't all that great. In fact, they are down-right terrible. For anyone wanting to read a not-so-happy short fiction, this may be right up your alley. As for me, I like a little more meat to my story, and will probably not re-read it anytime soon.
