Only the Good Spy Young by Ally Carter

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 as soon as her junior year. But that’s exactly what happened two months ago when she 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.

This is the fourth installment in the Galagher Girls series. Cammie is trying to come to terms with the events that occurred in the last installment. She is also trying to handle being the protected rather than the protector. The plot has twists and turns and hidden surprises.

All of our favorite characters are back in action, although some have different roles to play. Zach is of course back in the story. We get to learn some new things about Zach, which finally explain some of his weird behavior in previous books.
We get to meet Bex's parents in this book. We can see where Bex gets some of her awesome spyness from.

Overall it was a good edition to the series. It ended on a cliffhanger that I forsee taking us on a journey maybe beyond the Gallagher Academy's esteemed front gates and into the unknown.
