Lots of new information is set to be revealed in the book
Prince Harry is set to 'attack' Kate Middleton in his new biography that will reveal even more details about his falling out with the royal family and specifically Prince William.
The two brothers have not seen eye to eye for many years and plenty of fresh details are set to be spilled by Harry in the book that will be titled 'Spare'.
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 also mentioned that there will be some exploration of how Harry felt when his mother, Princess Diana, was killed in a car crash.
"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," they said.
There have been two recent TV interviews with ITV and CBS where Harry has fanned the flames of his falling out with his father and brother where he said that they were unable to reconcile.
