In his memoir, Harry reflects on his childhood and the loss of his mother, Princess Diana of Wales. He refutes rumors that his father, Charles, was not his biological father and instead attributes the rumors to tabloids fueled by sadism and lust for money. "Wonderful!,” Harry claims his father said, “Now you've given me an heir and a spare – my work is done." That quote has caused Harry quite a bit of grief throughout his life and has made him resent his father. He compares the dynamic between himself and his brother William, as the spare and the heir, to the dynamic between Princess Margaret and Queen Elizabeth II. Harry also discusses the pain he experienced from walking behind his mother's coffin at her funeral and the absurd conclusion of the investigations into her death. He questions why the paparazzi and those who sent them were not in prison and admits that he sought help from a woman claiming to have powers to connect with his mother.
In the memoir, Harry also admits to using drugs in his teenage years, including cocaine and cannabis. He also admits to losing his virginity to a woman much older than him in a field behind a pub, which is something that few expected of the Prince. He also talks about his deployment to Afghanistan and states that he flew on six missions that killed 25 Taliban members, something which angered the Taliban. Harry also claims that William and Catherine suggested he should choose a Nazi uniform for a costume party and that he fancied Catherine when he first saw her.
Harry also touches on his relationship with his father, Charles, and Camilla, as well as his relationship with William and Catherine. He recalls William's wedding, during which there was some ruckus in the family, and mentions that Caroline Flack, the late TV presenter who tragically killed herself, was a close friend of his. Harry also reflects on the relationship he had with the media and how he felt like he was constantly under surveillance because of his status. He alleges that the editor of the News of the World was adamant about gathering evidence of his drug use and describes the editor as a "loathsome toad,” which he felt about many people in the media.
Finally, Harry reflects on his relationship with American actress Meghan Markle, as well as their marriage, and the challenges they faced in the public eye–especially because of what he saw as the media’s obsession with Meghan. He details how they felt trapped and suffocated by the media and the royal family, leading to their decision to step back as senior members of the royal family in something which was called “Megxit”. Harry also touches on their son Archie and the challenges they faced in trying to provide a normal childhood for him despite what he saw as the constant media attention they face. He concludes by discussing the reasons why he wrote the memoir and his hopes and plans for the future.
