I hated how the authors chose to act as if Ursula's "thoughts" were fact when in reality they were nothing more than pure speculation. I only got a few pages in before I gave up. Apparently a lot of the real facts are taken from testimony and transcripts but the authors come right out and say Ursula's "thoughts and voice" are made up. One can guess that the authors aren't probably far off but the key word there for me is > 'probably'.
There are a great many books on the subject that do use real words and real thoughts, made known to someone/people prior to death that can be read.
If you're going to read this be prepared because the authors don't attempt to make it "normal". They're attempting to get people angry. IMO, this isn't needed. The kind of person reading this book is angry already. Ursula died at the hands of her parents. That's enough! Don't attempt to use your own thoughts to make me more angry.
Add to that to the typos and grammatical errors and it's all over.
