In the book Cissy talks about her daughter's severe drug problems and the downward spiral that led to her death by drowning in a hotel bathtub with traces of cocaine still in her system,"She started partying and didn't really know how to stop,i used to wonder what she was doing at night and where she was" Cissy says the thing that makes her really mad is that her daughter died alone.
