After quitting his top royal position, Prince Harry has teased royal admirers that he will publish a tell-all book on his tenure in the royal family.

His father, King Charles III, advised him to abandon the memoir, especially because Queen Elizabeth II had recently died.

Unfortunately for the future King, the Duke of Sussex has made it clear to the royal family that his tell-all book will not be canceled.

Instead, he would be updated to reflect his grandmother's death.

An anonymous source told Radar Onlinethat the book holds the key to the father-of-future two's in the royal family.

If the book is canceled, Prince Harry will return to the royal family. If the book is released, however, "trust will be irreparably harmed, and he will never again be allowed into the next King's inner circle."

"A line has been drawn in the sand," the palace insider added. "It's now up to Harry."

They went on to state that the decision in Buckingham Palace couldn't be clearer: either Meghan Markle's husband would choose his family, or he prefers the $20 million he received for penning the tell-all with Penguin Random House.

While the royal family is used to the Duchess of Sussex trashing them, seeing their own flesh and blood, such as Prince Harry, criticizing his family is a different story.

"If he burns this bridge, he will never be able to rebuild it."

The book of Prince Harry was supposed to be published in early 2023. However, Queen Elizabeth II's death may cause the date to be pushed back.

Another source informed the publication that the publisher does not want the book to be "out of date" once it is published, believing that delaying the release date will give the Duke of Sussex to ponder on his opinions.

The 36-year-old former royal said that "while this final parting brings us great sadness, I am forever grateful for all of our first meetings - from my earliest childhood memories with you, to meeting you for the first time as my commander-in-chief, to the first moment you met my darling wife and hugged your beloved great-grandchildren."

He went on to say how he cherished the times he spent with his grandmother and other remarkable moments and concluded by saying she and her late husband, Prince Philip, have already been reunited in peace.
