WHAT JUST HAPPENED!!! This was by far the best book in the series so far. I loved that we fially got to learn about Alex's dad. I'm also glad that Alex has a friend who knows about all this spy business. BUT THAT CLIFFHANGER!!! (view spoiler)[I was not expecting the book to end that way. I mean I"m sure Alex isn't actually dead since there's a whole bunch of books left. But I'm glad I didn't read this and have to wait for the next book, because the end was just so intense. If it weren't for the fact that there's so many more books, I would be so upset with how this ended. Alex is the main character and he can't die unless it's the last book, and even then I don't think I would be okay with it. (hide spoiler)] This is really my favorite one so far, and I can't wait to get my hands on the next one
