Serena Valentine isn't your average sixteen-year old girl. She's determined, stubborn, and decisive. She also happens to be an agent of the ICI; a spy commission only the government knows about. When Serena is assigned her first mission, it's the opposite from what she was expecting.
Serena must go undercover as a high school student at the school of Summington. She'll have to deal with her team, the craziness of high school, and the real definition of spy. High school was not anything Serena was expecting. But when you're a spy, you have to be ready for anything.
