Spy School Revolution

Superspy middle schooler Ben Ripley faces the Croatoan—a new evil organization that's so mysterious, 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 is looking forward to his life getting back to normal, or as normal as possible when you're a superspy in training. For once, everything seems to be right in Ben's world...until someone bombs the CIA conference room next door.
To Ben's astonishment, 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 is not a double agent working against the US, locate the fabled colonial-era insurgent group that's blackmailing her, figure out what their devious plot is, and thwart it.
But this time, Ben finds himself up...
