Step 1 . Enjoy your reading (this book was so good I expect you to get of your derriere and run through hail or snow to purchase United We Spy and not do anything else until you finish).
Step 2 Read until your eyes aren't inside your head anymore. Make sure you're more curious about the end of United We Spy than your eyelids are curious about your bottom lashes

I. Can. Not. Wait.


I AM CRAVING beyond my wildest hopes for:

* Zach & Cammie extraordinarily romantic original and crazy moments in obscene scary and potentially dangerous situations. Because, well, that's just awesome.
* An epilogue of promise of Zach & Cammie's happily-ever-after, a proposal would be very nice, even if just for the sake of assuring my mental stability
*(I know there's .000000000000000001% chance, but: Cammie's dad's 'remains' to show up in the lab as 'not his' and th

United We Spy was a brilliant conclusion to the Gallagher Girls series, and though I really enjoyed reading it, it kind of made me a little bit sad, because I had to say goodbye to one of my favourite series. I'm really going to miss Gallagher Academy and Cammie and Zach and Macey and Bex and Liz and I really don't know what I'm going to do now it's over. I guess on to waiting for Heist Society #4 and Embassy Row #1!

"The sixth—and final—Gallagher Girls novel. Look for it in September later this year." - Ally Carter

I only want to know one thing: When is Zach and Cammie going to get married?!


Omg. That cover and blurb. I assure you guys, tears will be shed when I finish this.
I know i am so lazy to do a review.

I re-read it last week and cannot contain the feels because of the ending.

I really need a epilogue for this.

Honestly, the series had just gotten even more AWESOME!!!! And Zach, (WHO IS SOO MUCH BETTER THAN JOSH) had just successfully stolen my heart! And...Ugh! I just need it soo badly!!! Why must you do this to us, Ally Carter?! Double Crossed is my only consolation!

A beautiful end to a terrific series that has accompanied me throughout the years. It makes me sad to to see it go, but happy to see how it ended. A series I will forever love and cherish.



I cannot wait- part of me is sad to know this series is ending, the other part, (The Gallagher Girl in me) IS THRILLED to the final showdown.

But.. as long as Zach is there, and he and Cammie ends up together, it's all good.

Hmm, if Josh returns, th

I hope it comes out soon, can't wait to see what happens with Cam. First going into the series I thought it was going to childish and just a bunch of teenage girls with spy equipment, but it's way better then that.

Now I really want to go to Gallegher Academy. Just let that sink into your head. It's a boarding school (i have a thing for boarding schools) that teaches you 100's of foreign languages how to use guns, scale buildings and a bunch of fighting techniques. Not AP calculus but a school t

I literally cried when I saw this cover. I HAVE NEVER CRIED AT A COVER.


Cammie--just, oh just look her! She's graduating! I can't believe it. And the pink/mauve!

Backstory: This series is what propelled me into the book world. After I fell in love with the first book years back, I saw that Ally would be at the RT Convention that was near me, so I went to meet her. And there was so many authors, and I got so many free books, and afterwards I devoured everything, got involved

“What is a Gallagher Girl?
She's a genius, a scientist, a heroine, a spy... a Gallagher Girl is whatever she wants to be.”

It took me forever to finally get the allure of Gallagher Girls, but I'm finally right here. United We Spy wrapped up neatly. Though I am a little bit sad, my favorites didn't even get an ample amount of screen time.

My only critique about this series is it could be slow, hence why it took me forever to get used to t

I have now completed the entire Gallagher Girls series and there is a hole where my heart should be because there is no more ?? That's it ?? That's not okay. I need more. I need more friendship, I need more family. I need more spies and mysteries. I need more Cammie, Bex, Liz and Macey. I need more Rachel, Joe, Abby and Townsend. I just need MORE.

Was this a good book? Yeah... it was okay. Was it a good end to a series? No. I wish I liked it, but I really didn't. I'll write more for this review later, but right now I'm just wallowing in the sadness of one of my favorite book series ending unsatisfactorily.

Now for some things that happened way too many times in this book

1. Blood running into Cammie's eyes

2. Cammie and Zach kissing "hard and fast"

3. People saying, "Don't play coy with me"

Covert Operations Report

Phase 6 (final).

With the completion of this difficult mission, the Operative would like to state that she has been pleasantly surprised with how much she enjoyed fulfilling her assignment and if given the choice, she might do it again.

The final phase of the mission was met by the Operative with rather high expectations, given the previous completed phases. The Operative believes that those expectatio

PRO: I read it mostly in one sitting, so avoided all spoilers.

CON: It's the last effing book.

PRO: I have no qualms about how Ms Carter finished the series, which is saying something.

CON: No, but srsly - it is the last book.

If I had my way, Ally Carter and I would get super chummy somehow and we'd drink lots of wine together while she regaled me with tales of what happened to each of the Gallagher G

Review written immediately after first read:
'United We Spy' was the best ending this series could've had. It was perfect.
Liz's graduation speech made me cry, because it was exactly what the entire series represents.
I could go on and on about what I loved about this, how strong of an opinian I have regarding it, and how much I loved the character development this book gave us. But it already is too perfect for words. It's just like

Such a good way to end an amazing, thrilling, adrenaline seeking series! I loved Cam and the person she grew to be. I loved the other characters and their plot twists. I loved how Ally wrote this book and honestly I felt so happy by the end of it. Cam is happy! Still in love with Zachary. :)
I'm so upset that this amazing series has ended :( I really loved Ally's books because they showed how to be a spy you can be anyone. You can be you. Such an amazing book and I would happily recommend d this

I'm doing a different kind of review for United We Spy because this is the very last book in the six-book, wildly popular Gallagher Girls series, and to try to summarize the plot at this point is like the time I was out of town when the Lost finale came out, and I ended up watching it with four other people who had never seen the show, and they kept asking questions during the show, and basically it just ended with me saying, "NO, it is not possible to summarize in five sentences" and "NO

Ahhhh!!! How am I supposed to wait an ENTIRE year for this book?? The ending to this book is going to be really bitter sweet. Bitter because I have followed these books for a very long time now, and will be very sad to see them end :(. And sweet because they're over! I will know what happens to Cammie, the rest of the Gallagher Girls, and Zach (oh Zach)

Pros and Cons of Waiting for GG6
1. Waiting! WHY??? Really, I was never a patient person, but this is pretty agonizing. Every day is one day
I'm actually just writing everything I'm feeling at the moment so..Here it goes...
I'm actually really really terrified for this book to come. Ally's been twitting stuff about ALOT of people dying and then another one about crying during Liz's graduation speech.

I'm really scared of that Ally really might kill off Cammie because I've become use to seeing things from her point of view and reading her character develop and become stronger. I'm afraid of something like her dying then carrying in som

Wow. I can't believe that this series is over. It's done. Finite. Wow.

I had high expectations for this novel, and I was not disappointed at all. This final book was fantastic. There was humor, romance, and everything required for an awesome book! This story was so well-written. You can clearly see how much the characters have grown since the first book. This book has non-stop action. One minute they are tracking down the Circle members, the next they're fugitives, then they are busting people ou

Everything I've ever wanted in a YA series finale. Kudos to Ally Carter for giving us Gallagher Girls what we want while adding all the twists and thrills we were looking for. You will not be disappointed--don't miss the short story in the B&N exclusive! Loved.
