Jackson Greene is riding high. He is officially retired from conning, so Principal Kelsey is (mostly) off his back. His friends have great new projects of their own. And he's been hanging out a lot with Gaby de la Cruz, so he thinks maybe, just maybe, they'll soon have their first kiss.

Then Jackson receives a link to a faked security video that seems to show him and the rest of Gang Greene flooding the school gym. The jerks behind the video threaten to pass it to the principal -- unless Jackson steals an advance copy of the school's toughest exam.

So Gang Greene reunites for their biggest job yet. To get the test adn clear their names, they'll have to outrun the school's security cameras, outwit a nosy member of the Honor Board, and outmaneuver the blackmailers while setting a trap for them in turn. And as they execute another exciting caper full of twists and turns, they'll prove that sometimes it takes a thief to catch a cheat.
