The highly anticipated book, Our King Charles III: The Man and the Monarch by royal correspondent Robert Jobson, is set to be released before King Charles' coronation this year. The book unveils numerous bombshell revelations about the royal family, including details about Charles' relationships with Prince Harry and Prince William, as well as insights into the Queen's final days at Balmoral.

One shocking claim in the book is that Prince Harry's demands before the Queen's passing left other royals "shocked." Harry was visiting the UK for the WellChild Awards when the Queen suddenly fell ill. Although he raced to Balmoral Castle to be with her, he did not arrive in time to bid her farewell. The book alleges that Harry decided against flying to Scotland with his brother and uncles after a disagreement over Meghan accompanying him, which did not sit well with the family.

Another revelation is Meghan's "curt, three-word" response when the Queen offered her advice. Jobson claims that the Queen suggested Meghan seek support from Sophie, Countess of Wessex, to which Meghan responded: "I've got Harry." This response reportedly surprised the Queen.

The book also covers the Sandringham Summit, where the Queen, Charles, and William met with Harry to discuss his and Meghan's future roles as royals. The Queen had the meeting room swept for bugs to prevent any leaks to the press.

The aftermath of Harry and Meghan's explosive Oprah Winfrey interview is another subject addressed in the book. Jobson claims that the interview destroyed trust between Harry and his family, prompting William to adopt a new strategy for dealing with the "renegade royals."

The book also alleges that the Queen was perplexed by the contentious texts between Harry and William, describing the Sussexes as "quite mad." Jobson writes that the Queen grew "tired" of the couple's criticisms, believing that Harry's love for Meghan was "clouding his judgment."

An explosive incident is detailed in the book, where Harry allegedly swore at King Charles during a heated phone call about finances. The Duke of Sussex had been discussing financial matters with the Queen, who grew weary and directed him to speak with his father instead. The conversation ended disastrously when Harry's demands for funds were not met, and tempers flared.

The book also discusses how Kate found a walkabout with Harry and Meghan to be one of the "hardest things" she had ever done. According to Jobson, Kate admitted to a senior royal that the joint walkabout was difficult due to the animosity between the couples.

The possibility of stripping Harry and Meghan of their Sussex titles was "discussed at the highest level," Jobson writes. Although King Charles is reportedly not in favor of this, other senior royals may be less forgiving.

Finally, the book claims that some royal insiders cruelly referred to Harry as "Meghan's hostage," even suggesting he had Stockholm Syndrome. These remarks were allegedly made behind the couple's back.
