Well, that was...not really any better than other reviews suggested.
I do appreciate that she says up front that religion is not a cure-all for eating disorders, but the book devolves pretty quickly into something very, I don't know, zealous. It's equal parts a book about how religion helped her get past an eating disorder and a book on how she was sinning by having an eating disorder, which...well.
(Side note: "I believe God allowed me to develop an eating disorder for a reason. I also know that since God is all-powerful, he has the power to free me from this burden whenever he thinks is best. It could be that God wants me to be anorexic for the rest of my life so I can learn from it and help others..." (page 101) Ack. That just seems like such a potentially damaging attitude.)
The other thing -- and as far as I'm concerned, this is a major flaw -- is that the book simply isn't written very well. Imagine a high school essay written by a reasonably bright student. Multiply it a few times to get something book-length (but don't multiply the variety of content, as there's a lot of repetition). This is roughly what you end up with. The writing might be fine in a different context, but for a memoir, it falls flat. Too much telling rather than showing; too much "This entry reveals...", "This entry shows", "I am talking about my eating disorder in this passage", etc.; no fully realised scenes or insights into anything other than her relationship with God. I'm not one for religion-based solutions to this sort of thing (although I recognise that religion can be beneficial), but that end of things, too, could have been enhanced by different choices in terms of how to show the story.
I've always liked the cover of this one, but it's one of the stronger parts of the book. I expect that there are valuable religion/spirituality-based books out there that might be helpful in recovery from an eating disorder (or other struggle), but I wouldn't suggest this one.
