Melissa is a nobody. Wilf is a slacker. Bondi is a show-off. At least that's what their middle school teachers think. To everyone's surprise, they are the three students chosen to compete for a ten thousand-dollar scholarship, solving clues that lead them to various locations around Chicago. At first the three contestants work independently, but it doesn't take long before each begins to wonder whether the competition is a sham. It's only by secretly joining forces and using their unique talents that the trio is able to uncover the truth behind the Ambrose Deception -- a truth that involves a lot more than just a scholarship. With a narrative style as varied and intriguing as the mystery itself, this adventure involving clever clues, plenty of perks, and abhorrent adults is pure wish fulfillment.

In Washington, D.C., 12-year-old Florian Bates, a consulting detective for the FBI, and his best friend Margaret must uncover the truth behind a series of private middle-school pranks that may or may not involve the daughter of the President of the United States.
