Ever since the Great Greene Heist, things have been going pretty well for Jackson Greene. Principal Kelsey is (mostly) off his back. His friends have terrific 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 shows him and "Gang Greene" flooding the entire school. The jerks behind the video say they'll send it to Principal Kelsey - unless Jackson steals a copy of the school's toughest exam. So Jackson and his crew reunite for their biggest job yet. To get the test and clear their names, they'll have to outrun the school's new security cameras, outwit a nosy member of the Honor Board, and outmaneuver the blackmailers while setting a trap for them in turn. And as Gang Greene executes another exciting caper full of twists and turns, they'll prove that it takes a thief To Catch A Cheat.
