I liked this book! I read it through in one sitting, and enjoyed the characters. The plot seemed predictable at first, but managed to surprise me a couple of times. All of the historical figures mentioned in the book are true, so it was lovely to learn some history while the characters pursue their mystery. A fun read, and it kept me interested!
I love the dynamic between the two sisters, Hero and Beatrice; very realistic and a brilliant addition to the story. The parents are really cool classy characters too. All-around good writing!
