Agents of Integrity: The Leprechaun’s Lucky Trap Is it a stroke of luck… or a calculated curse? St. Patrick’s Day at Franklin Elementary is usually about green cupcakes and paper shamrocks. But this year, the luck of the Irish has taken a dark, glittery turn. When the school’s drinking fountains start bubbling with neon-green liquid and the library is sabotaged with mysterious gold dust, the students are convinced a real-life leprechaun is on the loose. But R.J. Jordan and Nat Bratt know better. As undercover agents for A.O.I. (Agents of Integrity) , they know that where there’s "magic," there’s usually a motive. With the high-stakes Math Olympiad just days away, the pranks are escalating. From "cursed" hallways to disappearing supplies, someone is using the legend of the leprechaun to trip up the competition. R.J. and Nat must follow a trail of brass arcade tokens and neon duct tape to unmask the culprit before the school’s integrity—and the big trophy—vanishes for good.
