Only The Good Spy Young (Book 4)

Summary:

"When Cammie Morgan enrolled at the Gallagher Academy, she knew she was preparing for the dangerous life of a spy. What she didn’t know was that the serious, real-life danger would start during her junior year of high school. But that’s exactly what happened two months ago when Cammie faced off against an ancient terrorist organization dead set on kidnapping her.
Now the danger follows her everywhere, and even Cammie “The Chameleon” can’t hide. When a terrifying encounter in London reveals that one of her most-trusted allies is actually a rogue double-agent, Cammie no longer knows if she can trust her classmates, her teachers—or even her own heart.
In this fourth installment of the New York Times best-selling series, the Gallagher Girls must hack, spy, steal, and lie their way to the truth.as they go searching for answers, recognizing that the key to Cammie’s future may lie deep in the past."

Plot: Book 4 in the Gallagher Girl Series gets deep and I LOVED it! The Plot is non-stop as Cammie, Bex, Liz and Macey worry that their favorite teacher is really a traitor and Cammie is on constant watch. The plot gets more covert spy like as you realize the girls are getting closer to actually becoming field agents.

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.

Cons: NONE

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.
