Prince Harry's memoir, an object of obsessive anticipation worldwide since it was first announced last year, is coming out Jan 10.

The book will be called Spare and is being billed by Penguin Random House as an account told with "raw, unflinching honesty" and filled with ”insight, revelation, self-examination, and hard-won wisdom about the eternal power of love over grief.”
