These books are always hard to give a rating to. This is someone's life after all.
It's well written and if you want to know about the circumstance, I suppose I recommend it, but if you're only going to read one book on this subject, I prefered Tressa by Tressa Middleton. That might have just been because I read it first and a lot of the events portrayed here are the same.
Perhaps reading both is a good way to see the similarities in people's stories of these kinds of abuses.
