Prince Harry will launch his highly-anticipated memoir in January 2023.
Penguin Random House, which is publishing the book, unveiled a title, Spare, and launch date, Jan. 10, on Thursday.
"We are excited to announce the remarkably non-public and emotionally effective story of Prince Harry, The Duke of Sussex," Random House tweeted.
Harry, 38, is the son of King Charles III, and the late Diana, Princess of Wales.
He is the youthful brother of Prince William and the grandson of the late Queen Elizabeth II.
Spare will discover Harry's lifestyle from the loss of life of his mom in 1997 to the current day.
"It used to be one of the most searing photographs of the twentieth century:
two younger boys, two princes, on foot at the back of their mother's coffin as the world watched in sorrow -- and horror.
As Diana, Princess of Wales used to be laid to rest, billions were puzzled about what the princes ought to be questioning
and feeling and how their lives would play out from that factor on.
