Is there anything about the Di-and-Chuck saga that hasn't already been said? Christopher Wilson has decided that a book highlighting events from Camilla's perspective would fill a gap in the coverage of these events. It's a reasonable idea for a book, except that there's nothing to indicate he has talked directly to Camilla, and he's reduced to guessing what goes on in her mind.
Nonetheless, the book is an easy read and approaches the well-known story from a different angle, adding a few tidbits such as describing the Queen's raging hatred of Camilla. According to Wilson, it was Camilla who encourged Charles to marry Diana. The book is rather ambivalent in its perspective on Camilla, suggesting she saw no ethical dilemma in cheating on her husband to be Charles' mistress and orchestrating the sham marriage between Charles and Di. Yet in other passages, Camilla is shown in a sympathetic light. Even if Camilla is responsible for her own fate, it can't be easy being the most hated woman in Britain.
The book portrays Di's marriage as more of an empty shell than other authors have portrayed it. The author suggests Di knew what she was getting into, but was too naive and too intimidated to back out during the engagement. The marriage never had a chance; Di was never intended to be more than a showpiece. As the story is told in this book, the villain is Charles, who over and over is portrayed as self-centered even by the standards of royalty and utterly devoid of a moral compass or basic interpersonal skills.
The early chapters cover Camilla's family history. Skip those and jump into the middle of the book which is far more interesting. The book, written in 2002, ends with the author speculating that everyone should brace themselves for a Charles-and-Camilla marriage announcement, which of course occurred in 2005.
