Prince Harry is "torn" between wanting acceptance from his family and the love of his wife Meghan, a royal expert has claimed.
The Duke of Sussex has signed a four-book deal worth millions with Penguin Random House, with the first of these a tell-all memoir that was scheduled to go to press later this year.
There has been speculation in recent days that the date could be pushed back following the death of his grandmother Queen Elizabeth II.
However, once the book hits shelves, there will be no going back for Prince Harry, according to royal author Robert Jobson.
He wrote in The Sun : “Harry will no doubt be torn between wanting acceptance from his family and also the love of his wife. But he has now left himself in a Catch-22 situation.
"He has signed a four-book deal worth millions with Penguin Random House. He needs the money to fund his flash Californian lifestyle.
"Once that book, which is now written, hits bookshelves there will be no going back for Harry."
While no change to the publication date of Harry’s has been confirmed, many expect it to now be delayed until next year.
A source close to Harry and Meghan suggested the book would no longer come out as planned, although Penguin has not made any statement to suggest the Royal planned to pull it altogether.
In fact, the Duke of Sussex has reportedly insisted on its release on time, according to royal author Tom Bower, who said it would be coming out in November.
It's now been suggested that a delay could result in new material being added.
Ghostwritten by American author JR Moehringer, it's understood the book was written some time ago and tells the Prince's story of losing his mother Princess Diana, marrying wife Meghan Markle and quitting life as a Royal.
But with the Queen's death such a major event, the Telegraph has suggested the final draft could now be amended with an epilogue.
All members of the Royal Family will be in official mourning for the Queen for another seven days after her funeral on Monday, King Charles has already stated.
During this time, no one will be taking part in their usual duties and activities, and work will be phased back in gradually afterwards.
The Firm is said to be concerned by the Duke's decision to collaborate with the ghostwriter JR on what Penguin described as "the definitive account of the experiences, adventures, losses, and life lessons that have helped shape him".
Harry himself said it is a "wholly truthful first-hand account" of his life.
But Palace aides fear it will only do further damage to Harry's relationship with his family.
He and Meghan have already made multiple allegations since stepping aside, including during their bombshell interview with Oprah Winfrey in March.
