Princess The Early Life of Queen Elizabeth II by Jane Dismore
Unfortunately, I found this book a bit dull except for some interesting snippets of gossip, such as whether the Queen Mother was nicknamed 'Cookie' because she was really the daughter of a French cook and Edward VIII's attraction to the Nazi's. (You only have to look at the Queen Mother with her mother to see that this is not true). The book became livelier when Prince Phillip started courting the Princess.
It's certainly well-researched and worth reading if you like to read about the Royals or biographies in general.
I received this free ebook from Net Galley in return for an honest review.
