On Tuesday, Harry will release his tell-all memoir Spare.

What the book will include, and what will be revealed about the Royal Family remains unclear. Several members, including King Charles, Prince William, and Kate Middleton, are likely to feature, though some reports suggest that Harry’s father might actually be spared from most of the criticism.

Willam and Harry’s relationship has been a big talking point in the last year. Whether or not the brothers will ever be able to mend their broken relationship is a question only time can answer. Yet one royal expert is now suggesting might put an end to any hopes of William and Harry plastering over the cracks.

It’s believed that William might be heavily criticized by his brother in Spare. Not only that, but Kate could be too, according to royal commentator Daniela Elser.

Harry and Meghan’s Netflix documentary – released in early December – was the beginning of the next chapter for the Sussexes. After the infamous Oprah interview, things had been relatively quiet regarding their opinion of the Royal Family after they left for pastures new. That changed abruptly with the Netflix series, though neither Meghan nor Harry mentioned too many names in particular.

Harry’s tell-all book ‘Spare’

On January 10, however, Harry is set to publish his memoir. It has been a talking point for a long time, and several reports have revealed that his book – published by Penguin Random House – is bound to create new tension between himself and the rest of the Royal Family.

Some say it will include sections focusing on the rift between Harry and William and the presently-strained relationship between Harry and his father, now-King Charles. But now, reports suggest that Kate Middleton also will get her fair share of criticism.

Harry’s tell-all book has been said to be an “accurate and wholly truthful” account of his life.

The Prince dropped the news that he was writing a new book four months after the now-infamous Oprah interview aired.

“Prince Harry will share, for the very first time, the definitive account of the experiences, adventures, losses, and life lessons that have helped shape him,” Random House said in the press release, teasing the book as an “honest and captivating personal portrait.”

New details about Harry’s book were disclosed recently, and the release date is January 10. It will be named Spare, and there has been speculation that it might address Harry’s “spare” role as the second son of a king. Other reports suggest the meaning behind it focuses on that fact that he has been “spared” from the Royal Family now that he has left.

Harry reportedly paid $20 million upfront for ‘Spare’

No matter what, it’s generally rumored that the memoir will paint a negative picture of his family. According to Page Six sources, the book will contain several truth bombs.

“It’s juicy, that’s for sure,” one NY publishing source told the news outlet.

“There’s a lot of new stories in there about the past that Harry has not spoken about before, about his childhood … there is some content in there that should make his family nervous,” another publishing insider added.

Despite making plenty of money from his previous work, Harry will be raking it in when it is released. According to Page Six, he’s already received “at least $20 million upfront” from his publisher, Penguin Random House.

May 6 will mark the 4th birthday of Harry and Meghan’s son, Archie. How the couple reacted to the fact that King Charles’s coronation will be on the same date has not yet been revealed. Neither has it been confirmed whether Harry and Meghan will even be invited.

Some reports argue that King Charles is furious, and doesn’t want Harry and Meghan to attend. Others claim that Charles, irrespective of all that has been said and done, wants his son and daughter-in-law in attendance.

Kate Middleton reportedly criticized in Harry’s book

In a short clip from an upcoming television interview with ITV – one of two interviews that air Sunday before the book release – Harry refused to commit to his father’s coronation.

“There is a lot that can happen between now and then. But, you know, the door is always open, the ball is in their court,” he said. “There’s a lot to be discussed, and I really hope that they are willing to sit down and talk about it.”

As mentioned, several Royal Family members will reportedly be criticized in Harry’s upcoming book. That includes Kate Middleton, whom Harry used to have a great relationship with.

Harry first met and was introduced to Kate in 2003 at Highgrove. The Duke of Sussex was around when his brother, Prince William, invited Kate to meet his father at Prince Charles’s family house.

“I actually went bright red when I met [him] and scuttled off feeling very shy about meeting [him],” Kate admitted.

“William wasn’t there for quite a bit of the time initially, he wasn’t there from Fresher’s Week, so it did take a bit of time for us to get to know each other, but we did become very close friends from quite early on.”

According to reports, Harry was excited when he saw his brother’s future fiancée. Author Christopher Andersen, who has written the book “Brothers and Wives: Inside the Private Lives of William, Kate, Harry, and Meghan,” claims that Harry was very impressed when Kate entered the room.

Harry & Kate Middleton – relationship

“When Will’s girl looked away for a moment, Harry dropped his jaw and mouthed the words: ‘Oh my God, she is gorgeous!’”

Indeed, Prince Harry and Kate got along in the beginning. A University friend of Prince William and Kate, Jules Knight, said:

“Kate and Harry got on like they’d known each other forever.”

While William has always been the more severe type, Kate and Harry found they could relate to each other on another level. According to friend Jules Knight, Harry and Kate enjoyed a playful bond.

“They were always full of fun when they were together. They were joking around all the time – always trying to find ways to make each other laugh,” said Knight.

Harry and Kate friendship was perhaps strongest before the former fell in love with Meghan Markle, former actress on the television series Suits.

Harry and Meghan began dating in July, 2016, and things quickly picked up momentum. The two became a couple, and Meghan and Kate became good friends after a while. However, as you likely know at this point, things didn’t end well.

Today, Kate and Meghan’s relationship is not what it once was.
