Super-spy middle schooler Ben Ripley takes on the Croatoans, a new evil organization so mysterious that the only proof it exists is from the American Revolution, in this latest addition to the New York Times bestselling Spy School series. 

With SPYDER defeated, Ben Ripley looks forward to his life returning to normal--or as normal as possible when you’re a super-spy-in-training. For once, everything seems to be going Ben’s way...until someone bombs the next-door CIA conference room. 

To Ben’s shock, the attacker is none other than Erica Hale, the spy-in-training he respects more than any other. Ben refuses to believe Erica is working for the enemy...even if the rest of the CIA does.

His mission: prove Erica isn’t a double agent working against the US, locate the legendary colonial-era insurgent group blackmailing her, find out their devious plot, and foil it. 

But this time, Ben is up against opponents he’s never faced before: his own friends. They aren’t as quick to trust Erica as he is, and Ben is forced to rely on his own wits and skills more than ever. How can he succeed if he doesn’t even know who he can trust?
