Prince Harry's new memoir is set to hit shelves early next year as publishers described it as "raw unflinching honesty'.

The Duke of Sussex's book, Spare, is set to be released on January 10 with the title's name in reference to the phrase “the heir and the spare”.

The highly anticipated book was set to be released this autumn but was rumoured to be pushed back as a mark of respect following the Queen's death. 

The Prince's new book is being published by Penguin Random House shared that the book will take readers back to Princess Diana's death saying: "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."

The memoir has already been described as a 'landmark publication' with the Prince's words on "revelation, self-examination, and hard-won wisdom about the eternal power of love over grief.”

The book sales will also support charities, as donations will be made from the proceeds of the book and will help both Sentebale and WellChild.

There is speculation that royal family could face damaging newspaper headlines as the book is sharing the Prince's first-hand experiences.

Questions are being raised on if the Prince will reveal which member of the monarchy he claims made a racist comment about the potential skin colour of his then unborn son Archie or shine a light on his strained relationship with his father and troubled times with his brother William, the Prince of Wales.

When the deal to publish the memoir was first announced in 2021 Harry said about the book: “I’m writing this not as the prince I was born, but as the man I have become.”

He added: “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.”
