Mary Stuart - Queen of Scots, is a biography of the deceased queen. Mary has been known as a bit of femme fatale and Guy was intent to write a accurate and highly-researched biography of said queen.
This book is not for everyone. Unless you are interested in reading about this type of subject...HISTORY...then, this might be a bit of a snooze fest. However, I really enjoyed it. Ever since my mom had me listen to The Six Wives of Henry VIII, I've been very interested in the different monarchies and how everything played itself out.
I would definitely recommend this book, if you are interest in learning more about the Queen of Scots. I would also recommend The Six Wives of Henry VIII, in case you haven't read it either!
