You can read more of my reviews at Queen of ContemporaryI’ve loved Carter’s books since before I started blogging, when I didn’t really know what I was picking up. I’d go into a bookshop and pick up anything I liked the look of with no preconceptions or presumptions. I didn’t know of the hype surrounding these books until I started seeing them pop up wherever I went and then, when I finally became a part of the blogosphere, I realised that these books have a special quality that people gobble up in handfuls.United We Spy is the last book in the Gallagher Girls series and I was very worried about reading it beforehand. How could I say goodbye to this series that I have loved so dearly? The events of the last book meant that I knew this was bound to be dramatic, but I’d forgotten just how action-packed these books are.In United We Spy, we see the familiar array of characters embark on their last semester at the Gallagher Academy, which, I must tell you, made me feel very nostalgic! It seems like yesterday I was reading my way through the first book, and then the second and third and fourth and fifth. I felt all the emotions when reading this. Even after finishing, I’m still clinging on to the world fiercely. It’s definitely not a series I’m going to forget in a hurry.Cammie still had to overcome the issues that she was left to face after the events of the last book and we see her develop even more in this one. She has to deal with some really hard stuff and is thrown into lots of difficult situations but it seems like she always comes out stronger.I really loved seeing Bex, Liz and Macey again. Liz was as nerdy as ever but also has to face her own demons, as do Bex and Macey. The girls are all so loyal to each other which is very admirable. I’d love to be friends with them!United We Spy was a brilliant conclusion to a much-loved series and I’m so sad that I won’t be anticipating another book in this series any more. At least we have the Heist Society novels to keep us busy!
