Query: Disappointing

The novel, "Shadows of A Princess" by P.D. Jephson was a little disappointing to read. When I picked out this book I thought it was going to be full of facts about Diana that nobody was aware of. While some of the facts were new to me, others were not.The book though enlightened me on how difficult of a life Diana lived. She always seemed to be so happy, but this book really showed how troubled her life really was.
