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.

4) More Zach
5) More Zach/Cammie moments

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

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

Operative Sabrina

Upon gaining access to the novel Only the Good Spy Young by subject Carter, the Operative was able to ascertain the following:

~ The romance is undeniably evivident throughout. According to Operatives Sutton, Baxter and McHenry, Operative Morgan is "in love" with an asset who had firsthand knowledge of the Blackthorne Institute.

~ Said asset has shown to reciprocate feelings towards Operative Morgan. The asset is privy to s

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

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

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 actual

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. ...more

This series has gone downhill so much since the first book. I think Ally Carter's lost sight of her original plan? Book 1 was firmly tongue-in-cheek, with girls making bombs in chemistry class and being taught how to kill a man with a piece of uncooked spaghetti. But with each new book, the Gallagher Girls have moved more and more into Deep and Serious territory, and I think that's a mistake. I don't want to read about torture and death and mountains of angst. I want schoolgirls running around i ...more

During the fourth part of the mission the Operative managed to uncover some of the mystery that shrouded the mission and move accordingly to what she believed was the right course of action. She continued the mission.

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. ...more
