This is Ally Carter's first book in her YA series, "The Gallagher Girls", about a prestigious school for exceptional girls who are becoming spies. It is told from the perspective of 15 year old Cameron Morgan, a.k.a "the Chameleon", and daughter of the headmistress of the Gallagher school. Cammie and her best friends, Liz and Bex, can handle anything thrown at them, literally. They speak multiple languages, can hack high security computers, and can kill an enemy with their bare hands, but when Cammie meets a normal boy in the nearby small town of Roseville the friends are at a loss. Their subsequent "surveillance" of "the subject" and the help they receive from the newest Gallagher girl, Macey McHenry is a romping good time. This is an action packed fun filled read with just a few serious side notes to make it more believable. I am now anxious to read Ms. Carter's subsequent novels in the series (she has 4 books published in the Gallagher Girls series at this time and says the series will be 6 books total).
