Cammie Morgan always knew that being a Gallagher Girl (aka spy-in-training) would mean a life of risk and danger. She just didn't know that life would start before she'd even left high school...

But now that an ancient terrorist organisation is dead-set on kidnapping her, even Cammie "The Chameleon" can't hide. And when someone she trusts is labelled a rogue double-agent, C

There is no school cooler than the Gallagher Academy.

There is no profession more exciting than being a spy.

You know how Harry Potter is THE DEAL?

Well, this is MY Harry Potter.

I would choose to become a Gallagher Girl over a witch anytime.

Also, you'll want to have book 5 close to you when you finish this book. Trust me.
April*procrastinator and proud*
why? because:
1) More Spying
2) More action
3)More answers
4) More Zach
5) More Zach/Cammie moments

wow... WOW!!!! WOW!!!!!
oksy now that I'm done... i liked the ending! I hope she brings Zach with her! hehe it was his idea afterall. (you'll find out what i'm talking about when you read the book) Honestly i thought the Gallagher Girls books were getting repetitive

I've always been a fan of the Gallagher Girl series. I think that an all girls school for spies would be an absolute dream, don't ask me why because I really don't know. But Only the Good Spy Young was another interesting addition to the series and left me hanging for more. The Circle, an organization of double agents, has been tracking down and trying to capture Cammie Morgan, a junior at the the Gallagher Academy for Exceptional Young Women. There, she learns how to survive the most dangerous ...more

This book was SUBSTANTIALLY better the previous books. Not only did the writing mature but so did the characters ((and Cammie wasn’t AS annoying))

There was a PLOT!! In this book and thank goodness bc I was thinking of trashing it. It was fast paced, exciting, packed with twist and turns (albeit they were predictable at time) but it really did leave you feeling excited for more in the series.

The mystery in this book is much more developed than the

This book was not as amazing as I expected it to be. It went above and beyond any expectations I had at all, and I loved every second of reading it. Ally Carter does a great job of including all of the sweet and funny aspects that readers have come to know in her writing, but she also shows the darker points of humanity, including a double cross, cruelty, and above all, secrecy. With a completely out-of-the-blue shocker to end the book, Ally Carter has a new masterpiece on her hands. Well done! ...more

REREAD (audiobook) 2018: SUCH QUALITY. gg is such an underrated series.
Ally Carter is not finished writing this series, but I may be finished reading it. A shame, because it started out so different and positive and kind of cool. The worst to be said was that it was a little too naive and upbeat. But it's published by Hyperion, which is owned by Disney, so all the sparkles are a little expected. Besides, this series boasts ideas such as girl power, loyalty, and even self respect over cute boys (unheard of in YA, right?) so it's a great series for younger girls.

Oh my gosh, I loved this book so much. I flew through it in several hours. It was brilliant and amazing. The best Gallagher Girl book yet, and that's saying something because I absolutely LOVE every single book in the series.

Questions, oh the questions that are answered in Only the Good Spy Young! Ally Carter ties up so many strings, yet leaves about a zillion more questions you want answers to in their place.

We meet old characters and new characters too. I just love Liz. She's one of my favor
I haven't read this in years. But all I can remember is ZACH!!!! <3 <3

Second read - 9/06/17:
This book. I can't even. That ending. Those last 50 pages. Intense as f. And ZACH. Is my precious baby. I love him so much. I mean ☺😍😍😍😍😍😍😍 Cammie and him are so good together and so romantic and just ❤❤❤

Ally Carter has done it again! Her Heist Society series was the first I'd ever read of Ally's, and I just adore those characters (yes, present tense adore. And just Hale *sighs*) and the ridiculous cleverness of everything that this author creates. I gave this series a try at my sisters' insistence, and I'm so glad I did!
Ally has a way of making characters that you just want to hang out with and laugh over a bag of M&Ms, and the situations and humor in her stories: WARNING! There WILL be ac
This book is definitely the best in the series to far terms of the plot, characters, and the writing. It reminds me a bit of Harry Potter. The writing, subject matter, and perspective on life are all maturing as both the characters and readers mature.

This installment was stuffed full of intrigue, betrayal, pain, fright, and hope. I stayed up till 3 am just to finish it because I kept saying one more chapter, or I'll stop as soon as I figure this out. Before I realized it I had read half the boo
These seriously keep getting better and better. I started this book at 1:30am, it is now 4:30am and I've finished it. I can't even remember the last time I read a book in one sitting. I didn't even stop to go to the bathroom, it's just been three solid hours of reading. I just seriously love these books so much. I love all these characters and the plots just keep getting more intriguing.

Awesome! I absolutely loved the book, but it was confusing, seeing as I didn't the other books. I realized when I was about one-third of the book, but like always, I couldn't stop reading it, if I did I'd probably dread not finishing the book. :P

Something that never fails to irritate me: A person is in danger and needs to be protected, but nobody tells her what the hell is going on. Especially if said person in danger is a girl who is training to be a spy. There is a disconnect there, especially when she gets into as much trouble as she does. Nobody tells Cammie anything when she's a key person--they all just expect her to fall in line (yeah, right, when has she ever done that?). It's crazy how they can teach the girl how to undermine c ...more

Very interesting. Can't say I saw the plot twist coming, but I'm still very confused on different parts. The language was equal to the second book, with a couple 'heck's and a 'hell'. Quite a bit of blood. Mentions again of hotness and guy who are hot. A mention of a teacher's sexy bra. Two semi-detailed kisses, and two no-detailed kisses. Maybe it's because Cammie and I are the same age that I don't like Zach much (I know, I know, all the fangirls will attack me for that), especially at the end ...more

Note: At this point the Operative had to go to ground in order to regroup and continue with the mission.

He's just gone.
Someone has to tell Rachel.

Safe to say I shed a lot of tears.

Never fails to amaze! Plot is gripping and chockfull of secrets and surprises. I find myself thinking, "one more chapter then I'll wash the dishes," but you know how likely that is when you're in the middle of a great book. In most series, the first book is the best then the novels the come after get gradually worse and worse, but with Ally Carter's books, they maintain the amazing quality.

Ahh i so want to read this book. I reckon Zach is the one who gets labelled as the rogue operative cause he always turns up where cammie is and that guy from the circle of cavan knew him and why wasn't he at blackthrone? Ahh cannot wait until it is out... Joe Soloman hs been labelled a double agent:(
This is the bridge book of the series. And - I guess because it’s all setup - I have no memory of reading it for the first time. (I think the plot details were all folded into book 5 in my memory.) This is the point where the series begins to change, begins to work within its worldbuilding instead of within the world as we know it (Dr. Fibs’s earlier experiments aside), but it hasn’t fully committed yet. What you get as a result is a half-baked school story with some teasers for book five folded ...more
