I will definitely call her crazy. I read this book as fiction/entertainment, rather than out of interest for Ms. Heche or her life.
I almost think I would prefer if she presented this as fiction. The memories she "dredges up" -- most of which have been refuted by her family, friends, and anyone who knew her -- are so far-fetched and incredulous, I'm worried that she actually believes them to be true. Yes, it would be lovely if we could remember what happened to us at 18 months, but it's just not going to happen...
I can tell it was written in six weeks.
More of a rant against Christianity, and beliefs she no longer embraces.
Yes, she had a tough upbringing, but she also made her choices.
I would pass on reading it, if you have the option. Hardly worth your time.
