One fact everyone seems to know about Princess Diana these days is that she was an ace manipulator of the media.

But in reality, says Ros Coward, who has interviewed those closest to her for the first authorised biography, she promoted her image only for the good of others – and it was she who was manipulated Since then she has been branded as the ultimate media Machiavelli, a skilful and devious self-publicist. If at times overly worshipful, the book is nonetheless a lovely compilation and a fitting continuation of Diana's legacy, as the book's net royalties will be donated to projects supported by her Memorial Fund.Princess Diana died seven years ago today. Coward is careful to show numerous facets of her subject, though the theme of Diana's extensive humanitarian work dominates, while difficulties in her personal life are downplayed. Predictably, they all speak reverentially of her, but the extensive quotations set the book apart from many Diana biographies and show just how far her influence extended (''All the landmine stuff was jolly brave,'' says Sandy Gall of Afghanistan Appeal ''She made me more nervous than many military opponents,'' reflects Colin Powell, who led her to the dance floor at a charity gala for cancer).

The text relies primarily on interviews with those who knew (or even briefly encountered) the princess, from photographers to lawyers, fashion designers to fellow aid workers. Unfortunately, Coward doesn't pair the pictures with captions, so if one isn't familiar with every detail of Princess Diana's history, it can be frustrating to try to decipher what the images show.

Many images and testimonies will be familiar to her fans but some-particularly the ones depicting her early years dancing and swimming, attending boarding school and working at her first job-have never been published.

It's also rich with photos from just about every one of Diana's 36 years. Coming as it does with that seal of approval, it should be no surprise to readers that this large, glossy book is tasteful and keenly decorous. The tributes to the life and career of Lady Diana continue with this lavish production, authorized by her estate and Memorial Fund.
