As the title suggests, Prince Harry's "Spare" is mainly about his brotherly quarrel with Prince William

As the title of Prince Harry's memoir, Spare, suggests, readers can expect the tell-all book to be "in effect about the sibling rivalry between Prince Harry and Prince William," The Sun reports that sources say that "the brother's right to become king due to Harry's "resentment and sense of unfairness" will reveal that he has always played second fiddle to the "older William," the report said. (Marie Claire reported yesterday that it is indeed William who is getting the bulk of the criticism in the book, according to a source familiar with the book.)

"Prince Harry's book will take the feud with his brother William to a new level by telling all about the feud." The Sun reports.

"[William and Harry's] falling out will be covered in detail in the book, and what is infuriating is not that outsiders are revealing these private moments, but that Harry is speaking one-sidedly about family issues," says one source. 'Harry and William were supposed to be together and supportive of each other. Their mother, Princess Diana, always warned them that they should never get along. It is very sad that it has come to this stage."

King Charles seems to have gotten off relatively easy in this book, with sources claiming that the monarch "loves his son very much" and that the dinner door is "always open" whenever Harry is in the UK. One note on King Charles" "Camilla is King Charles' redline," the source says. If Harry treats Camilla like "trash," Charles could pull her down and Harry knows it". Harry had a difficult relationship with Camilla, who was having an affair with his father when he was still married to Diana. But attacking Camilla would not go down well with the palace staff or his father, and Harry is aware of that". (We are told how William, Charles, and the Crown Princess are portrayed in the book, but there is no mention yet of how Camilla is portrayed by Harry.)

Prince Charles seems open to reconciliation, but according to the Daily Mail, William is feeling betrayed and angry at his brother's attacks. Things have been threadbare for months, and it seems unlikely that Harry's memoirs will help."
