I have "Born to Rule". It's pretty informative if you ask me. It goes into detail about Ena's wedding. Alix's courtship with Nicholas II as well as Maud's and Marie's. I don't know about Sophie though...I haven't read that far yet. There's two sets of photos in it. They're ones I haven't seen before.
