Hallemann's book notes that Jackie had long been fascinated by royalty and visited Buckingham Palace in June 1961. The author says the Queen gave practical advice — to "dole out your energy and take care of yourself when you're on this public stage" — and the two women found understanding amid public life.
The book also compares Princess Diana and Carolyn Bessette Kennedy, both challenged by intense media pressure. Diana admired Jackie and later worked to use attention for causes, while Carolyn struggled to cope. Both women shaped cultural style before and beyond their sudden deaths in the late 1990s, the author writes.
