Query: The "Unreal" Princess Diana

The motivation for writing this book is to make Prince Charles a palatable figure. Everything that went wrong in the Wales' marriage is Diana's fault. The author glorifies people like Nicholas Sommes -- he was brilliant to discover that Diana had personality disorders. Poor Charles was only trying to define love when he said that he did not know what love is.No good purpose is served by this book. The general public has no need to know the details Princess' private life. The so-called author has a need to delve into Diana's sex life too and makes judgments about her.The author also thinks she knows more about Diana's relationship with her mother than Diana did.The author touts herself as a lady. Not in my estimation. She does not mourn Diana's loss as stated on the jacket. Shame on the pain she has caused Diana's sons and supporters by this piece of trash.
