Characters: I think you see a lot of progression in most of the characters, but my favorite appearance is Mr. Zachary Goode! Although, he is mysterious as ever!
Pros: Fun! Thrilling, Overall a great book in the series and not disappointing by any means.
Final Thoughts: I was so impressed with Only The Good Spy Young, mainly because the series although, entertaining was definitely the "young" part of Young Adult.. so it was nice to see this book take a more darker and older turn. I could not stop reading.
