Like most writers, I am a reader. One of the hardest things a writer or a reader has to do is say goodbye to beloved characters. On September 17th, Ally Carter's final installment of the Gallagher Girls series, United We Spy, will be released. Though all of her fans are counting down the days and hours until it is released, reaching the last page of this compelling series and saying goodbye to Cammie Morgan and her friends will be difficult.
