"By day, seventeen-year-old Fiona Spangler runs small cons for her ritzy prep-school classmates, getting them out of tests and forging fake hall passes. But by night, Fiona joins her dad on riskier heists - stealing back the clue-filled forgeries her mom scattered across the country before she disappeared. Fiona desperately hopes that her mother will be waiting at the end of the scavenger hunt she left behind. And they are so close. Just three more heists remain, but then disaster strikes when Fiona's dad is captured by the FBI. Desperate to finish the job and save what's left of her family, Fiona assembles a crew of teen criminals: a master of disguise who can transform into anyone, a talented hacker who only communicates in glares, and a rival con artist with a vendetta against - and a possible crush on - Fiona. All they have to do is perform three nearly impossible heists, solve her mother's incredibly complex clues, and evade the FBI. Easy, right?" -- (Source of summary not specified)
