There is a secret division of the British Security Service named CHERUB, which employs kids and teenagers as intelligence officers. In the first book, The Recruit, we are introduced to the main character, James, and his younger sister Lauren. They don’t really have a home after the death of their mother – but things change when James is recruited by CHERUB, who must undergo rigorous training to become a secret agent. All of the highly trained CHERUB agents are under the age of seventeen, thus adults never suspect that these teens are spying on them. James’s sister is soon recruited into CHERUB as well. James and the other agents of CHERUB go on dangerous undercover missions, and of course, things always go wrong to stir up the plot. I would recommend The Recruit and the rest of the CHERUB series for anyone looking for a funny, clever, and action packed book series great for teen boys or girls.
