During a spy school game of Capture the Flag, twelve-year-old Ben Ripley accidentally shoots a live mortar into the principal’s office—and immediately gets himself expelled. Not long after going back to the boring real world, Ben gets an offer to join evil crime organization SPYDER. And he accepts.
Ben can tell he’s a key part of their sinister plan, but he’s not quite sure what the plan
is
. Can Ben figure out what SPYDER is up to—and get word to the good guys without getting caught—before it’s too late?
