There's a whole thread devoted to the book--it was very popular! Just do a search by title in this section and it will pop up.
Royaltybuff---I loved the sections dealing with George V and Queen Olga. I hope JG does justice to his relationship with Marie Alexandrovna as well. Despite the 'marrying Missy' debacle, they were very close. Based on readings, it seems these 2 disparate personalities were 2 of his favorite relations.
I'm early into the book (after some quick skimming) but feel that a bit of short shrift has been given to their early lives. That is a bit of a disappointment. That was one of my favorite parts of Pope-Hennessey's landmark bio on Queen Mary--that she actually had a life before she was Duchess of York, Princess of Wales, Queen. However, JG's strength lies in her storytelling ability--rather than straight historical facts, she really weaves you a story. It reads more like historical fiction--in a good way!
I would recommend the book to someone looking for this type of book, definitely.
