With an IQ of 242, Antonia Scott is officially the smartest person on Earth. Her intelligence earned her the title of “Red Queen” of a secret, experimental police project, but what seemed like a gift turned into a curse, and she ended up losing everything. When the son of a powerful tycoon is found gruesomely murdered in her mansion, and the daughter of Spain’s richest man is kidnapped, the Red Queen organization springs into action. Mentor, Antonia’s former boss, turns to Jon Gutiérrez, a temperamental Basque police officer about to be fired from the force, to revive Antonia. The twisted game of cat and mouse that Jon and Antonia engage in during their investigation also helps them discover that they admire and complement each other almost as much as they irritate each other.
