In this follow-up to the Edgar-nominated Spy School, top-secret training continues into summer for aspiring spy Ben Ripley—and so does the danger.

Ben Ripley is a middle-schooler whose school is not exactly average—he’s spent the last year training to be a top-level spy and dodging all sorts of associated danger. So now that summer’s finally here, Ben would like to have some fun and relax. But that’s not going to happen during required spy survival training at a rustic wilderness camp, where SPYDER, an enemy spy organization, has infiltrated the spies’ ranks. Can Ben root out the enemy before it takes him out—for good?
