The definitive biography of Diana, Princess of Wales, written with her full cooperation and the closest the world will ever come to her autobiography. As the thirtieth anniversary of her death approaches, this landmark #1 New York Times bestseller remains the essential account of her life inside the British royal family.

When Andrew Morton’s Diana: Her True Story was first published in 1992, it transformed the world’s understanding of Princess Diana and the House of Windsor. Its revelations were initially greeted with disbelief, but the truth later emerged: Diana herself had participated, recording candid answers to Morton’s questions and entrusting him with the story she wanted the public to hear.

In her own words, Diana speaks with extraordinary honesty about her marriage to Prince Charles, his relationship with Camilla Parker Bowles, her appeals to Queen Elizabeth II, her struggles with bulimia and mental health, the pressures of royal life, and her devotion to Prince William and Prince Harry. The result is an unprecedented portrait of a woman trapped between the demands of the monarchy and her determination to reclaim her voice.

In this updated edition, Morton returns to Diana’s private recordings to reveal further insights into her life and examines her enduring influence. At a moment when new claims and competing recollections are once again reigniting debate about Diana’s marriage, treatment, and legacy, this book stands apart: it is not simply another account of Princess Diana, but the story she chose to tell.

An icon in life and a legend in death, Diana continues to captivate readers around the world. Diana: Her True Story—in Her Own Words is her most intimate and authoritative account—and the closest thing to the autobiography she never had the chance to write.
