Prince Harry netted a £14.5million advance for his memoir and will donate the profits to charity, it has been reported.
The Duke of Sussex has been working on the book about his life growing up as part of the Royal Family.
In a statement confirming the upcoming release, the Duke said: "I'm writing this not as the prince I was born but as the man, I have become.
“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.
“I'm deeply grateful for the opportunity to share what I've learned over the course of my life so far and excited for people to read a first-hand account of my life that's accurate and wholly truthful.”
Now, The Sun reports, citing royal expert Robert Jobson, that Harry has received a multi-million pound advance for the title.
According to publisher Penguin Random House the profits from the book will go to charity.
A blurb from the publisher read: “In an intimate and heartfelt memoir from one of the most fascinating and influential global figures of our time, 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.
“Covering his lifetime in the public eye from childhood to the present day, including his dedication to service, the military duty that twice took him to the frontlines of Afghanistan, and the joy he has found in being a husband and father, Prince Harry will offer an honest and captivating personal portrait, on that shows readers that behind everything they think they know lies an inspiring, courageous and uplifting human story.’"
They promised the book would be “an honest and captivating personal portrait”.
Meanwhile, a source told the Mirror the thought of the book has sparked a “tsunami of fear” in royal circles.
They said: “There is a now tsunami of fear among the royals over what Harry will write.
"Many hope he may correct a few things but do not hold much hope."
Last month, his wife Meghan published the picture book 'The Bench' through Random House Books for Young Readers.
The transcript for Harry's book was due to be handed in next month but due to the birth of the couple’s second child, Lilibet and other commitments, it has now been pushed back to October.
The book's ghost-writer J.R. Moehringer, 56, has previously written memoirs for tennis legend Andre Agassi and Nike co-founder Phil Knight, as well as his own autobiography, “The Tender Bar,” which is currently being made into a movie by George Clooney.
