Details on new Prince William and Princess Kate book

According to the Mirror, the book promises to give “never-before-told context about the biggest stories to have followed the Prince and Princess of Wales in recent years – including the Sussex departure, the forming of the ‘Cambridge way’, and the death of Queen Elizabeth II – and provides an unprecedented glimpse into the private lives”.

This biography moves beyond the headlines as it explores love, resilience, and their journey together.

The description reads: “Highlighting the couple’s resilience and dedication in the face of the adversity, Russell presents a deeply personal perspective on how the events the Prince and Princess have weathered together will shape their vision for a modern monarchy – as they set out to secure its safe continuation at a time of extreme change and turmoil.”

Russell says: “I’ve spent almost a decade following The Prince and Princess of Wales as part of the royal pack and have always believed there’s so much more to the couple than the spectacle reveals. I am immensely grateful to Ebury for granting me the platform to explore the unseen.

‘Seismic revelations’ set to emerge

“The result is a truly intimate portrait of William and Catherine; providing not just unparallelled insight into who they are as individuals, but seismic revelations about them as a couple and the world they inhabit.

“This biography moves beyond the headlines as it explores love, resilience, and their journey together as they navigate their public duties amid this unprecedented era.”

In addition, Lorna Russell from publisher Ebury Spotlight describes the book as “powerful and revealing”.

Lorna adds that Russell provides a “new perspective on our future king and queen, and we get to know a very real family, living their lives behind the pomp and ceremony”.

She says this book will “completely change the narrative on the royal family, in unexpected ways”.

William and Kate’s ‘brutal’ year

The Prince and Princess of Wales faced a tough ordeal as Catherine was diagnosed with cancer in 2024.

The Princess of Wales shared her diagnosis publicly in March of 2024. She then took a step away from royal duties to focus on her treatment and her health.

In January 2025, Kate announced she was in remission. She has since been gradually returning to duties.

In late 2024, Prince William detailed how tough 2024 had been as Catherine underwent treatment at the same time his father, King Charles, also did for his cancer diagnosis.

Speaking to reporters in South Africa, William admitted: “It’s been dreadful. It’s probably been the hardest year in my life. I’m so proud of my wife, I’m proud of my father, for handling the things that they have done. But from a personal family point of view, it’s been brutal.”
