Who is Cammie (Cameron) Morgan from Only the Good Spy Young and what is their importance?

Cammie is the book's central character, its narrator, and protagonist. Her situation, attitudes towards that situation, and action taken as a result of both attitudes and situation define and motivate the book's action as well as manifest its central themes. She is intelligent but not beyond letting her feelings occasionally overwhelm both her intelligence and her good judgment, although there are indications throughout the narrative that she is becoming adept at finding a better balance between the two. She is also loyal to her friends and family, particularly those who have earned her loyalty.
