I had read several books about Jacqueline Kennedy prior to reading this book. Her relationships with John F. Kennedy and Aristotle Onassis were not new information to me. I also knew about her relationship with her sister, but I got a lot of details about that from this book that I had not known before. Most of my reading has centered around the Kennedy family, as opposed to the Bouvier family. I hadn't known very much at all about Janet until this book, so it was really valuable to be because of that. I have other books by J. Randy Taraborrelli, and I enjoyed all of those. This one was no different. The facts and stories were told in a way that made the book a very interesting and entertaining read, and I always feel that this author does his due diligence on research for his books.
