Prince Harry's controversial book looks set to focus on his strained relationship with his brother William, and could damage their relationship forever, royal experts have said.
The book - Spare - is released on Tuesday, January 10 and has been ghost-written by JR Moehringer known for his expertise in strained father-son relationships.
But although Duke of Sussex’s memoir does go into details about his father the King, it is the heir - his brother William - who gets a verbal bashing in the Spare.
The book, published by Penguin Random House, has been available for pre-order since October and reached the number one spot on Amazon both in the US and UK.
It is set to be one of the biggest books of 2023 with the audiobook version being read by Harry himself.

A source with knowledge of the book told the Sunday Times: "Generally, I think the book [will be] worse for them than the royal family is expecting.
“Everything is laid bare. Charles comes out of it better than I had expected, but it’s tough on William, in particular, and even Kate gets a bit of a broadside.
"There are these minute details, and a description of the fight between the brothers. I personally can’t see how Harry and William will be able to reconcile after this.”
The source added the book explores in depth Harry’s grief about his mother’s death, which he touched on during his Netflix documentary Harry and Meghan.
They said: “The overall impression is that this is a man who has never recovered from the trauma of his mother dying so young, and then along comes Meghan and he projects on to her a parallel with Diana.”
The book's back cover reads: "It was one of the most searing images of the twentieth century: two young boys, two princes, walking behind their mother's coffin as the world watched in sorrow - and horror.
"As Diana, Princess of Wales, was laid to rest, billions wondered what the princes must be thinking and feeling - and how their lives would play out from that point on.
"For Harry, this is that story at last.
"With its raw, unflinching honesty, Spare is a landmark publication full of insight, revelation, self-examination, and hard-won wisdom about the eternal power of love over grief.
"Prince Harry wishes to support British charities with donations from his proceeds from Spare.
"The Duke of Sussex has donated $1,500,000 to Sentebale, an organisation he founded with Prince Seeiso in their mothers' legacies, which supports vulnerable children and young people in Lesotho and Botswana affected by HIV/AIDS.
"Prince Harry will also donate to the non-profit organisation WellChild in the amount of £300,000.
"WellChild, which he has been Royal patron of for fifteen years, makes it possible for children and young people with complex health needs to be cared for at home instead of hospital, wherever possible."
