As someone who followed her career and personal life struggles since 2007, and witnessed her big comeback in 2008, I would say this book is everything I needed to know about her.
In retrospect, I always felt that something wasn't quite right with her. It seemed like she wasn't fully present most of the time, lacking passion or something else. Some fans attributed it to the knee injury she had a few years back, but deep down, I always knew it was something more profound.
Now, we all know what was truly going on, and it's incredibly sad to see how much she sacrificed her freedom just to be with her own kids. I believe she still has a lot more to share, and this book hasn't covered everything we wanted to know. Perhaps there will be a volume 2?
