Charles Spencer to Release New Book Telling the Truth About Princess Diana

As the thirtieth anniversary of Princess Diana’s tragic death approaches, her brother, Charles Spencer, has announced plans to publish a new memoir titled Swan Song: Diana, My Sister on September 22. Aimed at setting the record straight, the book will be published in Britain and other countries by Penguin Random House and translated into 12 languages.

The Bottom Line

• The Release Date: Swan Song: Diana, My Sister drops on September 22, published by Penguin Random House across multiple territories and languages.
• The Motivation: Following renewed interview requests tied to the upcoming 30th anniversary, Earl Spencer decided to document his firsthand memories directly.
• The Editorial Mission: The book targets long-standing narratives Spencer describes as untruths that solidified into accepted public facts over the decades.

Rewriting the Narrative Ahead of a Somber Milestone

Diana died in a fatal car crash inside the Alma tunnel in Paris in August 1997. Alongside her died Dodi Fayed, the son of the late Egyptian billionaire Mohamed Al-Fayed.

Enter Charles Spencer. In statements released by Penguin Random House, the Earl shared that repeated media inquiries surrounding the upcoming anniversary convinced him to take control of his thoughts and memories “once and for all.”

Publisher Daniel Byniard characterized the project as a work of historical significance. It chronicles the life of one of the twentieth century’s most culturally enduring figures through an intimate, familial lens.

Author	Charles Spencer (Earl Spencer)

Release Date	September 22
Global Reach	Translated into 12 languages

Spencer noted that much of what is currently accepted as conventional wisdom about his sister is built on cumulative fiction. By stepping forward to speak positively and candidly, he aims to re-anchor her legacy. He recalls Diana as a dynamic, deeply loving, and charismatic individual who simultaneously wrestled with intense vulnerabilities and a profound lack of self-confidence.

Spencer’s explicit goal is reaching younger readers who possess no living memory of Diana at the height of her global prominence.

The Cultural Legacy and Publishing Landscape

By grounding his upcoming book in personal history, Spencer positions his work as an authoritative corrective. The global rollout—spanning multiple international territories and a dozen language translations—signals major retail backing from Penguin Random House.
