Finding Freedom would translate into a documentary easily. It doesn’t provide much more insight than the tabloids did. That being said, they did have more personal information about Diana. 

I do love Harry and Meghan. I love their story, although it's definitely not the ending that the world expected. And this book covers it all in detail, written by two people who were there during the events or had access to people who could tell them what happened. It's extremely well-written and pulls at your heart because it is an emotional story of two people finding their places in an extremely unrealistic life. Just a great book I can see myself revisiting in years to come!
