Prince Harry’s long-awaited memoir will touch on a number of issues including falling in love "with a woman his family didn't accept" and the grief of losing a parent.
Announcing its title and publication date, publisher Penguin Random House said the 416-page memoir was filled with "insight, revelation, self-examination, and hard-won wisdom", written with "raw, unflinching honesty".
According to royal executive editor Omid Scobie writing for Yahoo, Harry's memoir will cover issues that will "resonate with readers from all backgrounds".
"Coping with grief and the tragic loss of a parent, the struggles of accepting oneself, sibling rivalry, and falling in love with a person your family doesn’t accept are all part of the duke’s very human story," he writes in his latest column.
He said large parts of the book will also cover Harry's time serving in the military in Afghanistan, as well as the joy he has found in becoming a husband and father.
Despite speculation that the memoir will include further criticism of the Royal Family, Scobie said it will not "trash" Harry's relatives, but "actually offers a more sympathetic look at the realities of their near-impossible existence".
He added that there were "no last-minute rewrites or edits after the Queen’s death" - relating to claims that Harry had rowed back on some elements after his grandmother passed away.
But the longstanding royal commentator admitted that despite this, there is still the risk of "serious blowback" on Harry from senior Royals amid concerns over the damage his book could cause to relationships within the family and their reputations.
Watch: Princess Diana would 'completely' support Prince Harry's upcoming memoir
In an announcement shared on the official website for Harry's book on Thursday, Penguin Random House said the memoir will be published globally on January 10, 2023.
It has also released a cover image, which features a photo of the prince looking directly into the camera.
Harry and Meghan announced they were stepping down as working royals in early 2020.
Since then they have criticised the royal family, with claims including racism and a failure to support them or protect them from the press.
In July last year, Harry announced that he was penning a memoir that would expose the "mistakes" and "lessons learned" across his life.
"I'm writing this not as the prince I was born but as the man I have become," he said at the time.
"I've worn many hats over the years, both literally and figuratively, and my hope is that in telling my story — the highs and lows, the mistakes, the lessons learned — I can help show that no matter where we come from, we have more in common than we think."
The couple are also set to release a Netflix documentary giving insight into their lives.
