By day, seventeen-year-old Kiera Johnson is an honors student, a math tutor, and one of the only Black kids at Jefferson Academy. But at home, she joins hundreds of thousands of Black gamers who duel worldwide as Nubian personas in a secret multiplayer online role-playing card game. No one knows Kiera is the game developer, not her friends, her family, not even her boyfriend. But when a teen in Kansas City is murdered over a dispute in the online world, news of the game reaches mainstream media, and it is labeled a racist, exclusionist, violent hub for thugs and criminals. Even worse, an anonymous troll infiltrates the game, threatening to sue Kiera for 'anti-white discrimination.' Driven to save the only world in which she can be herself, Kiera must preserve her secret identity and harness what it means to be unapologetically black in a world intimidated by blackness. But can she protect her game without losing herself in the process?
