Released last summer, Finding Freedom – a biography of Prince Harry and Meghan Markle – featured numerous revelations about their time as senior royals.
Now, the book is set to be reissued this summer with fresh chapters covering the Duke and Duchess of Sussex's move to the United States and their explosive Oprah Winfrey interview.
It will also provide an inside look at other recent events experienced by the couple, including the alleged bullying of palace staff and Prince Philip's death earlier this month.
The authors – journalists Carolyn Durand and Omid Scobie – will also lift the lid on Harry and Meghan's Netflix and Spotify deals, as well as the Queen's decision to strip them of their royal patronages.
Initially released in 2020, the original version of the book details their story from 2016, when they met, up until they stepped back from royal life.
However, readers will have to wait a little while to get their hands on the updated edition, which is set to go on sale on 5 August.
When the biography first came out, its 24 chapters – based off more than a hundred interviews – featured some shocking claims.
Billed as "the true story of Harry and Meghan", it revealed that the duchess was offended by the Princess Michael of Kent’s blackamoor brooch, and how the duke grew apart from close friend Princess Eugenie following the Archie pregnancy reveal at her 2018 wedding.
Durand and Scobie said that all the "unknown details" they unearthed were confirmed by at least two sources, and came from "unique access and [was] written with the participation of those closest to the couple".
However, the duke and duchess – who are awaiting the arrival of their second child, a daughter – have stated that they were not involved in the creation of the book, which is widely considered to be a flattering account on their part.
A spokesperson for them previously said: “The Duke and Duchess of Sussex were not interviewed and did not contribute to Finding Freedom.
“This book is based on the authors’ own experiences as members of the royal press corps and their own independent reporting.”
