It's been so long since I've read the other two books. But this one did not disappoint! I could have used more Zach in it though. :( And that twist! :O I mean I heard about that happening later but I didn't think it was related to what was going on during this book. Okay I thought I was going to die from the feels during the train scene with Cammie and Zach! Ah! My favorite part of the book! Really can't wait to begin Only The Good Spy Young, which I'm starting tonight!
