So far, this book is about how George Washington has formed the spy ring. My favorite character in the book is George Washington because I like how he formed a spy ring and the new type of invisible ink. I also think he was very clever and smart. I liked it when I found out that Benjamin Church was a double spy and he turned out to be good. I didn't like the part when George Washington lost his letter about his teeth and it is really sad that the first president had bad teeth. You might want to read this book if you like the Revolutionary War, spies or George Washington. I think that the book should be a little more in the war-zone because the book itself is about the Revolutionary War. My favorite part of the book is when the rebel army crosses the Delaware River and captures many enemies.
