What Princess Diana's brother reveals in his deeply personal new memoir

Princess Diana is back in the spotlight, nearly three decades after her death, as her brother, Earl Charles Spencer, releases a deeply personal new memoir about the sister he knew long before she became one of the world's most famous royals.

Earl Charles Spencer's new memoir, "Swan Song: Diana, My Sister," is officially out today, Tuesday, Sept. 22, giving royal fans a deeply personal look at Diana's life through the eyes of someone who grew up alongside her. The book's release comes amid a public dispute between Spencer and King Charles III over claims in the memoir about Diana's death and the royal family's response to it.

In the book, Spencer looks back on the childhood he shared with Diana, from their years growing up on the family estate to boarding school and the turmoil surrounding their parents' divorce. He also reflects on how dramatically her life changed after she married the then-Prince of Wales, now King Charles III, as well as her relationship with her sons and her humanitarian work.

Spencer's story ultimately leads to the heartbreaking final days of Diana's life and her death in Paris on Aug. 31, 1997. As the brother who delivered her famous eulogy at Westminster Abbey just weeks later, Spencer offers a perspective that is both deeply personal and rooted in decades of shared memories.

Now that "Swan Song: Diana, My Sister" is officially available, readers can finally get their hands on Spencer's account of the sister he knew best. Here's everything to know about how to order your copy of Spencer's new book today.
