Apparently I'm the only one on Amazon who didn't like this book.
There's nothing much wrong with the writing, though I did get irritated with the dialogue after a while because the author constantly calls everyone "love". What I didn't like was the exploitative nature of this book, and from looking at Glass's other publications it seems all her books are on the same theme. These are not her stories to tell. It makes me extremely uncomfortable that she is making money and gaining fame from writing about the abuse of children, children who aren't hers. Looking after them for a few months doesn't give her the right to write books about them, that is up to the survivors themselves. We do hear about the effects on Cathy and, to a lesser extent, her family (I wonder if her husband wanted to be distanced from these books as he is certainly a background character) it is really all about Dawn, and Dawn is certainly not receiving any of the profits from the book sales.
I also did not like the self-congratulatory feel of the book. Although Glass often talks about how she felt people would blame her for the suffering of the children in her care, it is clear that she always felt this would be unjust and that she was the only one doing the right thing for the child and it was everyone else's fault that it didn't work. Even more often it is mentioned how great a parent she is, often from the mouth of Dawn. Her website has the same tone.
