I love this series!!! After learning that an ancient terrorist organization is out to get her, Cammie Morgan has been watched 24/7. But while in London Cammie meets her covert operations teacher and realizes that everything or everyone isn't always what they seem. Now all of her teachers and the other spy organizations are out to get her teacher who is in the organization and make him pay. Can Cammie stay safe, prove that her teacher is innocent, all while dealing with the very mysterious Blackthorne boy Zach? Read to find out! Very interesting and lots of movement though not so much as the first three.
