Helter Skelter was the absolute best true crime book I have ever read. From the very beginning, the book captures you into the lives of the murderers, victims, and prosecutors. It does a remarkable job at building the story line so that you are not overwhelmed with information, but are still well informed with details and specifics. I also loved that the book went into the past of Charles Manson and the "family". Over all this was an EXCELLENT book, and it was very hard to put down!!
Positive
