Kiera Johnson is an honors student, a math tutor, and one of the few Black kids at Jefferson Academy. At home, she joins hundreds of thousands of Black gamers, who duel worldwide as Nubian personas in the secret multiplayer online role-playing card game, SLAY. When a teen in Kansas City is murdered over a dispute in the SLAY world, the game is labeled a racist, exclusionist, violent hub for thugs and criminals. No one knows Kiera is the game developer-- until an anonymous troll infiltrates the game, threatening to sue Kiera for "anti-white discrimination." Can she protect her game without losing herself in the process?
