Teen Review: “United We Spy” by Ally Carter
In the sixth and final Gallagher Girl novel, Cammie Morgan must fight the Circle of Caravan one last time to stop their destructive plan to start World War III. To figure out what the Circle members are planning, she must find the descendants of the names she remembered in the last book. But while she is looking for them, they are being picked off faster than she can find them. So with the help of her friends, Cammie must break into a incredibly secure prison to rescue a descendant of a Circle family who happens to be her friend. Can they together figure out what the Circle is planning and stop it before it goes too far? This book was a good conclusion to the series. You can clearly see the progress of the characters over the six books.
