James Vagus and Dakota Walker are teen agents in America's covert MIS-X program-trained to think fast, fight smart, and trust no one except each other. What starts as a routine assignment in Rio de Janeiro turns into a global scavenger hunt when nuclear launch codes vanish, threatening to ignite a World War III. From the streets of Marrakesh to the casinos of Monte Carlo and the deserts of Nevada, every clue draws them deeper into a shadowy world of double agents and false alliances. But when they're forced to team up with two Soviet operatives-Nadya and Sasha-the line between friend and enemy blurs fast. Can rival spies work together long enough to stop a possible global catastrophe, or will old loyalties destroy them first?.
