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 that Cammi

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!

Like Out of Sight, Out of Time, United We Spy was darker than the other boo

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

I really need an epilogue for this.

Omg. That cover and blurb. I assure you guys, tears will be shed when I finish this.

* girls who are spies
* let me repeat that: this is a series about girls who are literal spies, they go to spy school
* the main focus is FRIENDSHIP. BETWEEN GIRLS. No stupid rivalries, no girls being evil with each other, no popular/mean girls vs the outcast. None of this.
* the first book is fluffy and funny and more lighthearted but if you think that the rest of the series is t

A hysterical, speechless mess.

This is me finding out it won't come out until later 2013! I CAN'T WAIT THAT LONG!!!! Need...Gallagher...girls!


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!

This series was tiring as hell. Was it good? Kinda? Was it fun? I guess. Was it over the top? Most definitely.

I don’t regret reading this series, it’s just after the first 3 books, the novelty of ‘spy academy girls school’ kinda wore off and I was just slugging my way through the rest of the books.

It includes some of your favourite tropes like ‘petite teenage girl takes down armed men’ and ‘bunch of teenagers save the world’ and ‘terribly irrational decisions’ a

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, that

Things that will could happen in the Sixth and last :( Gallagher Girls book :
(A list by Ginni Ann Morgan, probability equations done by Elizabeth Sutton)

1. Someone very important is going to die. Ex. Mr. Solomon... Probability: 9/10

2. There is going to be a huge Gallagher Girls vs. Circle of Cavan War. Probability: 8/10

3. There will be a final Josh-Zach battle. Probability: 9/10 (Go team ZACH!!!)

4. More memories of 'Summer-Cammie' time will be remembered (forced to remember). Probability: 6/10

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 invol

“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
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. ...more

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

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
By Anna Sk (hereafter referred to, for the last time, as "The Operative")

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

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

I'm kind of sad because I read this without bothering to reread the series and I felt like I lost my connection with some of the characters (Zach, Preston, Townsend??) I remembered them but vaguely and it made me sad. Hence, a reread for the Gallagher Girls is definitely on the cards.

Even though I was like ? for a bit at the beginning I STILL LOVED THIS. The Gallagher Girls has always been one of my favourite ser

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
This book as an ending to the Gallagher series has definitely satisfied me. I have no complaints even a bit. This book is a page turner and kept me on the edge of my seat. It seems real like I was with them as I feel the tension and intensity of the situation the main characters are in.

Another thing that pleases me is that finally! Liz has an important role to portray in their mission. I was definitely rooting for her the entire time.

I like how the author has ended each character’s stories and
