Prince Harry sells 1.4 million books in English in just one day

Harry released the book "Spare", a book that portrays his memories on January 10, and soon sold more than 1.4 million copies in English in just one day.

"The first full day of sales of 'Spare' represents the biggest first day of sales for a non-fiction book ever published by Penguin Random House, the largest publisher in the world," the company said.

The book has been edited and is available in 16 languages, both in physical, digital and audiobook editing (narrated by Prince Harry himself).
