Prince Harry's long-awaited memoir will finally hit shelves in January and it's been confirmed it will have the very telling title - Spare.
Publisher Penguin Random House have billed the memoir, being released on January 10, as a book of "raw, unflinching honesty" - and royal insiders have labelled the choice of title as "confrontational" and "yet another attack on the royal family". A description of the book, due for release on January 10, from publisher Random House claims it will take "readers immediately back to 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".
It adds: "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 his 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."
It's unclear exactly what will be included in the book, but if it is anything like interviews Harry has given since quitting as a working royal - it is likely to be highly explosive.
But what unanswered questions about Harry and Meghan could be addressed in the book? Here we take a look...
What happened on the day the Queen died?
With Harry's book being released just months after the death of his grandmother the Queen, will it go into detail about what happened on the day she passed away?
On that day, September 8, Harry and Meghan happened to be in the UK visiting when news broke that the Queen's health had taken a turn for the worse.
This prompted royals to rush to Balmoral to be by her side and there was some confusion over whether Meghan accompany Harry on the trip.
Harry eventually travelled alone but didn't take the same RAF jet from London as Prince William, Prince Andrew, Prince Edward and Sophie Wessex, instead taking his own private jet.
He arrived at Balmoral on 8pm that day - almost five hours after the Queen died at 3.10pm, and was the first to leave the Scottish estate, having reportedly eaten dinner separately to William and dad King Charles.
Will he shed any light on this? Or will he divulge any details what led to him and Meghan joining William and Kate for a surprise walkabout in Windsor in the days after the Queen's death?
The 'royal racist'
One of the most shocking lines from Harry and Meghan's bombshell tell-all interview with Oprah Winfrey in March was a claim that Harry had "conversations" within the royal household about how dark son Archie's skin might have been before he was born.
During the interview, Meghan refused to say who the conversations had been with, saying it would be "very damaging to them".
Later in the chat, Harry also said he would never reveal the details of the conversations - although it was later reported the comments were not made by the late Queen or Duke of Edinburgh.
After the interview aired, a statement was issued by the Queen, which read: "The issues raised, particularly that of race, are concerning. Whilst some recollections may vary, they are taken very seriously and will be addressed by the family privately.
"Harry, Meghan and Archie will always be much-loved family members."
Meanwhile, Prince William hit back at the claims and insisted they were "very much not a racist family" when asked by a reporter.
But will Harry reveal more details about this in his new book?
Why did he leave the Jubilee celebrations early?
Back in June when the late Queen was celebrating her Platinum Jubilee, both Harry and Meghan came to the UK with their children Archie and Lilibet.
However, they made just one fleeting public appearance at a service of thanksgiving at St Paul's Cathedral.
They did also attend Trooping the Colour and were seen watching the military parade from a building overlooking Horse Guard's Parade.
However, they did not appear on the Buckingham Palace balcony as it was reserved for working royals only.
The couple did not join the royals for the Platinum Party at the Palace concert and left the UK before the Jubilee Pageant on the final day.
Will he reveal why this was the case?
What really happened at the Sandringham Summit?
In January 2020, Harry and Meghan made the shock announcement that they would be stepping down as senior royals and would become financially independent.
This prompted the Queen to host crisis talks with her grandson at Sandringham in a bid to find a solution to Meghan and Harry's future roles.
They were joined by King Charles, who was still Prince of Wales at the time, and William in what was dubbed the Sandringham Summit.
After the two-hour meeting, the Queen released a rare statement, where she said they had “constructive discussions on the future of my grandson and his family”.
It added: “My family and I are entirely supportive of their desire to create a new life.
“Although we would have preferred them to remain full-time working members of the Royal Family, we respect and understand their wish to live a more independent life while remaining a valued part of my family.”
In Robert Lacey's book, Battle of the Brothers, there are claims that Prince William felt betrayed and refused to eat lunch with his brother.
Will Harry tell all about what happened at the summit?
What really happened before the wedding that made Kate and Meghan cry?
There were numerous reports that Meghan made the Princess of Wales cry during a bridesmaid dress fitting in the lead up to her wedding to Harry.
But during her one-on-one with Oprah, Meghan claimed it was actually Kate that made her cry.
Meghan said she has now forgiven Kate, adding that she's a "good person" and that Kate sent her flowers to apologise for the incident.
Meghan says that the incident was a "turning point" in terms of her time in the royal family.
It's something that has fascinated fans, so people will be keen to see if Harry sheds any more light on it.
What caused the rift with William?
There has been much speculation about the growing rift between Harry and his older brother William.
It was reportedly sparked by William's concerns over Harry's fast-developing relationship with Meghan and the tense row quickly boiled over.
The younger prince then claimed in the Oprah interview that his brother was "trapped" within the royal system.
According to friends, William was "very upset" and "reeling" over the claims, with his head "all over the place".
Will Harry's book go into more detail about what caused the feud in the first place?
What is his bond with Camilla like?
Harry is said to have a rocky bond with his stepmother Queen Consort Camilla and there have been reports she could come in for criticism in the memoir.
Earlier this year, royal author Tina Brown said Harry can't stand" his father's second wife and didn't want her to be Queen.
She added he will "go after" her and Charles in the explosive book and that he has not made his peace with her. Will this be covered in the book at all?
Who denied Meghan help for her mental health issues?
During the Oprah interview, Meghan opened up about her mental health struggles and admitted she had suicidal thoughts during her time in the royal family.
She explained how she "didn't want to be alive anymore" and when asked directly if she was thinking of self-harm and having suicidal thoughts at some stage, Meghan replied "yes".
Meghan says that Harry "cradled her" when she told him, and he later admitted it sent him to a "dark place".
When she asked the palace to seek professional help, Meghan said she was told she couldn't get any.
Will Harry's book reveal who exactly told Meghan this?
