The 38-year-old Duke of Sussex will discuss loss, love, and recovery in his new memoir Spare.
Thursday morning, the publisher Penguin Random House announced the title and release date.
Without a doubt, "spare" comes from the proverb "the heir and the spare."
It is alluding to the divergent paths that have kept Prince Harry and Prince William apart since their birth.
Before William and Kate Middleton welcomed their three children, his younger brother was the next in line to the throne.
The text will include Harry's current relationships with the new Prince of Wales and the rest of the royal family, but the publisher neglected to disclose this.
The author's remarks concur with Harry's own feelings.
According to a statement from Penguin Random House, Harry will recount his story in Spare over 416 pages in "raw, unapologetic honesty."
